Chair's statement

On behalf of the Board, I am pleased to report on the six-month period ended 30 June 2023.

Simon Hogan Chairman

During the period, the Company has continued to deliver consistent growth in the value of our private portfolio, through implementing our distinctive strategy of investing in the clean hydrogen opportunities not readily accessible elsewhere. With the majority of IPO funds now deployed, our approach has focused on incremental investments in existing portfolio companies, backing these management teams to deliver their growth plans, and assessing new growth opportunities. ESG is fully embedded in our investment decisions, and the Board is pleased to see the introduction of six-monthly ESG reporting. The Company is dedicated to further developing and progressing our ESG framework to achieve the highest reporting and performance levels.

The Company continues to see strong support for the energy transition from governments around the world and views the policy focus in this area as a catalyst for further growth. The fundamentals of the hydrogen sector continued to strengthen, despite weak macro-economic conditions, enabling us to identify unique accretive opportunities to invest in, across the entire value chain of the sector. Today the Investment Adviser is tracking over 170 completed projects totalling 800MW globally. In addition, the Investment Adviser are monitoring 13GW in projects that are under construction or advanced development with investment in land, electrolysers and FEED studies. Some 4.5GW of this is under construction currently.

Overall, despite the uncertainty of the current economic environment, the Board remains confident that the Company is investing in a sector with a favourable outlook and believes in its growth potential as illustrated by the strength of our current pipeline of private clean hydrogen investments.

So far 2023 has seen the continuation of the market uncertainties created by the aftermath of COVID-19, and Russia's on-going invasion of Ukraine. This has resulted in high energy price volatility and supply chain issues, putting pressure on the economy, and contributing to inflation and higher interest rates. The Investment Adviser is seeing fundamental shifts in energy policy in many countries in response to this, in order to accelerate the transition to a low carbon economy and improve energy security.

However, share prices of the innovative growth companies required to enable this transition, including the Company's, have seen considerable pressure over the first half of 2023. The global downturn has also affected our ability to raise capital in 2023, having last completed an equity raise of £21 million in April 2022.

The Board continues to monitor wider market events as they relate to the Company, including the share price volatility in the market price of its shares and the discount to NAV at which the shares have traded through 2023. The Board is not aware of Company-specific factors that have led to the prevailing discount to net asset value to which the Company's shares trade and believes this is primarily driven by wider market events including the sudden, material rise in interest rates and an unfavourable macroeconomic backdrop. We are focused as a Board on improving the share price for our investors, and believe that this can be achieved by crystalising value through third party investment in portfolio companies, and asset sales, delivered to maximise NAV, over time.

In a further parallel development, listed funds have come under scrutiny from investors regarding the valuation of portfolios of private investments. The Company applies a consistent approach to portfolio valuation, centred on discounted cash flows, using the International Private Equity and Venture Capital Valuation 2022 ("IPEV") Guidelines. Share prices in the listed markets are reflected in the valuation of the Company through listed assets in the portfolio. The details of these valuations are set out later in this report. The resulting private valuation that has been set out in this report has an implied forward revenue multiple of 4 times 2024 expected revenues, which is some 30% lower than listed hydrogen sector multiples. This, the Company believes, underscores the robust and conservative approach we are taking to valuations.

The Board meets quarterly with the Company's Investment Adviser and holds regular meetings to review all of the Company's investment valuations. The Board also has regular contact with the Investment Adviser outside of formal Board meetings. I and other Board members attended the Company's Capital Markets Day earlier this year, and met some of our investors and analysts, and the management teams of all the private companies that we have invested in. The Investment Adviser has a dedicated investment team, and has the right to be represented on all of the boards of the private assets.

The Board and Company is committed to the aim of the Company that seeks to generate NAV returns of 10-15% over time, including proceeds from exits, whilst investing in clean hydrogen for a climate positive impact.

Our diversified approach to portfolio construction has provided resilience and our investment case has been reinforced further by macro tailwinds and supportive regulatory regimes in the clean hydrogen sector, particularly in the EU and the USA. More than ever before, we remain confident that the Company is investing in a sector with a favourable outlook and a substantial growth potential. Macro events have refocused efforts on the need to reduce global reliance on fossil fuels, with the Company well-positioned to continue investing in low-carbon growth, aimed at reducing harmful emissions, improving energy security and driving the energy transition.

Performance

During the period, the Company continued to selectively deploy capital into the clean hydrogen sector, totalling £8.0 million in the first half of 2023. The emphasis has been on follow-on investments in existing positions, with the 2021 IPO proceeds largely deployed. This comprised -

· One new private investment completed, at a green hydrogen production project at Thierbach, in Germany, managed by HH2E AG. The Company committed to invest £2.5 million (EUR 2.8 million) into further maturing this project, ahead of final investment decision, alongside other institutional investors and HH2E. To date, £1.9 million of this commitment has been drawn;

· The Company invested £2.9 million follow-on in hydrogen flight innovator Cranfield Aerospace Solutions Ltd, alongside Safran Corporate Ventures and the Strategic Development Fund;

· The Company invested £1.8 million follow-on in Sunfire AG, a leading electrolyser developer and supplier; and

· The Company invested £1.5 million follow-on in NanoSUN, a hydrogen technology, transportation and distribution business.

Including further follow-on investment completed post period end, the Company has deployed a total of £112 million, or 88% of the net proceeds raised of £126 million, into low-carbon growth companies.

At 30 June 2023, the Company's Private Hydrogen Assets comprised ten investments in hydrogen assets in the UK and Europe with an aggregate value of £117.5 million, as well as a small allocation to strategic listed hydrogen companies.

Eight of the Company's private investments, representing 89% of its invested portfolio by value, are revenue-generating, producing equipment and technology solutions for clean hydrogen production. The aggregate revenue from these investments was £52 million in the 12-month period to 30 June 2023, an increase of 170% from the prior year.

The total NAV on 30 June 2023 was £129.7 million, including a £120.5 million portfolio valuation, of which £3 million is in liquid, listed positions, £8.9 million is in cash held by the Company with other net assets of £0.3 million.

At 30 June 2023, the NAV per share of the Company was 100.70 pence, representing an increase of 3.87 pence per share (3.9%) in the 12 month period. The increase was driven primarily by valuation uplifts to the Company's portfolio of private investments, positively contributing 6.75 pence per share to the NAV increase.

Despite this growth delivery from our Private Hydrogen Assets, the Company's share price ended the period on a discount to NAV and in common with much of the investment trust sector, in large part due to unfavourable macro-economic conditions.

Earnings and dividend

The Company reported a gain after tax of £4.4 million for the period, equal to 3.39 pence per share.

The Company's dividend policy is to only pay dividends in order to satisfy the ongoing requirements under the Investment Trust (Approved Company) (Tax) Regulations 2011. The Company has paid no dividend during the period, as we continue to focus on growth investments.

ESG

Since our launch in 2021, we have set our focus for the Company specifically on investing in clean Hydrogen Assets and their role in the energy transition, combined with wider ESG principles, leading to avoided GHG emissions and targeting net negative emissions.

Our commitment to positively contribute to climate change mitigation, whilst integrating core ESG principles into our decision making and ownership process, is at the core of everything that we do as a company. The Company is classified as an Article 9 Fund, the highest classification under the SFDR regulation. We are a signatory of the PRI, a United Nations supported network of financial institutions that promote sustainable investments. In collaboration with our portfolio companies, we will push forward with our sustainable investment objectives as we continue to deploy capital in low-carbon growth.

In addition to a climate-positive impact, particular focus is placed on engagement to deliver effective boards and the encouragement of sustainable business practices. These, and other issues, are reviewed and integrated prior to any investment decision, and managed thereafter through close relationships with the Company's private company investments.

We are pleased to be once again publishing the external reporting of the Company's performance, including EU taxonomy alignment of our portfolio companies and avoided GHG emissions disclosures, which can be found in the ESG section of this report. This is the first interim report for the Company that reports on this basis.

Events after the period end

The Company completed a £1.0 million follow-on investment in NanoSUN alongside Westfalen and NanoSUN management.

Outlook

Our diversified portfolio approach has provided resilience and our investment case has been reinforced further by macro tailwinds and supportive regulatory regimes in the clean hydrogen sector, particularly in the EU and the USA. There are considerable uncertainties on the near-term macro-economic outlook and capital raising capacity of the listed funds sector. Nevertheless, we remain confident that the Company is investing in a sector with a favourable outlook and a substantial growth potential.

Whilst market sentiment is outside of our control, the Company anticipates the continued solid performance of our portfolio, revenue growth and delivery of key milestones will be catalysts for appreciation in our share price.

All of this underpins our target to deliver 10-15% annual NAV growth over time, and I believe that our Investment Adviser, whose principals have over 60 years of combined specialist experience and track record, is well-placed to deliver on these projected targets.

On behalf of the Board, I would like to thank all of our shareholders for their support, as we continue to grow our unique and diverse portfolio of leading clean hydrogen investments.

Investment Adviser's report

About the Investment Adviser

The Company's Alternative Investment Fund Manager ("AIFM"), Fundrock Management (Guernsey) Limited, (part of Apex Group), and the Company have appointed HydrogenOne Capital LLP as the Investment Adviser to the AIFM in respect of the Company.

Its key responsibilities are to originate, analyse, assess and recommend suitable investments within the hydrogen sector, and advise the AIFM accordingly. Additionally, the Investment Adviser performs asset management services in relation to the investments in the portfolio or, to the extent asset management is delegated to third parties, oversees and monitors such asset management.

HydrogenOne Capital LLP was founded in 2020 by Dr JJ Traynor and Richard Hulf as an alternative investment firm focused specifically on investing in Hydrogen Assets and their role in the energy transition. As a responsible investor, HydrogenOne Capital LLP is committed to contributing to the energy transition through the financing of sustainable investments and by providing investment solutions that reduce carbon emissions.

HydrogenOne Capital LLP employs a fully integrated investment and asset management approach and integrates its focus on ESG criteria throughout the entire investment process.

The Principals of the Investment Adviser

Richard has 30 years of experience in the Utilities and Energy sectors and is a Chartered Engineer, originally from Babcock Power and latterly Exxon. In addition, his financial experience spans stock broking, corporate finance, and fund management with Henderson Crosthwaite, Ernst & Young and Artemis Investment Management, where he invested into renewables companies. He has an MSc in Petroleum Engineering from Imperial College.

The Investment Adviser's team

The principals have assembled an experienced team to support the Company. This group brings a mixture of finance, technical and sector skills to support the Investment Adviser in its day-to-day activity. The Investment Adviser has established a team which is responsible for financial modelling, corporate and asset valuation analysis, and opportunity assessment for the Company.

Advisory Board of the Investment Adviser

The principals of the Investment Adviser are supported by an experienced team which comprises the Advisory Board. The Advisory Board has been carefully selected to provide expert advice to the Investment Adviser on the hydrogen sector, project finance and capital markets. The Investment Adviser has appointed the members of the Advisory Board to provide it with advice from time to time. No members of the Advisory Board are directors, officers, employees or consultants of the Company, the AIFM or the Investment Adviser. It is envisaged that the Advisory Board will expand over time, with additional experts being added or substituted as and when required.

Market review and outlook

The Investment Adviser recently published its annual review of the hydrogen industry, The Bluffer's Guide to Hydrogen, which is available on the Company's website, at https://hydrogenonecapitalgrowthplc.com/the-hydrogen-market/hydrogen-sector-reports/.

Policy makers and industry are converging on clean hydrogen as a core technology to deliver net zero, improved air quality and enhanced energy security.

The Paris Agreement in 2015 has led at least 40 countries to set out hydrogen policies and US$70 billion of funding as part of net zero targets to deliver the energy transition.

According to the World Health Organisation ("WHO"), some 4.2 million deaths per year are caused by poor ambient air quality, and 91% of the world's population live in places exceeding the WHO's air quality guidelines. Much of this pollution is a result of emissions from internal combustion engines and fossil fuel power plants.

The 2022 Russian invasion of Ukraine has compelled decision makers across the world to focus on the importance of sustained investment and policy support for domestic energy production and, crucially, less reliance on energy imports from overseas. This new drive is further amplifying the demand pull for clean hydrogen from energy transition and air quality needs. As a result, governments and industries have responded with new initiatives to deliver affordable, secure, and sustainable low-carbon energy, with clean hydrogen set to play a vital role.

Alongside this, following Russia's invasion of Ukraine, consumers have seen a significant increase in fossil fuel prices. This change, combined with substantial increases in regional natural gas prices, has improved the relative economics of clean hydrogen compared to grey hydrogen, which is currently the lowest cost and most polluting form of hydrogen supply.

2020 saw EU targets for hydrogen to meet 14% of Europe's energy needs by 2050. In 2022, the EU reshaped its energy policy to the REPowerEU 2030 plan, which calls for an implied over 300GW of clean hydrogen by 2030, compared to 80GW in previous plans. Some EUR 5.4 billion in hydrogen subsidies have recently been approved under Important Projects of Common European Interest ("IPCEI"), which are expected to unlock a further EUR 8.8 billion of private investment. The Hy2Tech scheme, also announced in 2022, links 41 projects and 35 companies building out the hydrogen sector, and has qualified for IPCEI funding. The EU's Hydrogen Bank will auction EUR 800 million of opex subsidy to green hydrogen in 2023. There are additional sources of grant funding at a country level in multiple EU countries.

In the United States, the Department of Energy has announced a US$8 billion programme to develop clean regional hydrogen hubs across the country, as part of net zero ambitions by 2050. The 2022 Inflation Reduction Act set aside US$369 billion for climate and energy proposals. This is expected to make green hydrogen cost competitive with grey hydrogen, and make US clean hydrogen amongst the lowest cost in the world.

In the UK, 2030 clean hydrogen targets have been doubled this year to 10GW. The UK Government has recently announced a national clean hydrogen subsidy scheme called Hydrogen Business Model ("HBM"), which will use a contracts-for-difference style set-up to help fund an initial 1GW of clean hydrogen projects in 2023, as part of the target to reach 10GW of low-carbon hydrogen by 2030, in a potentially £9 billion sector. This is in addition to the Net Zero Hydrogen Fund ("NZHF") with up to £240 million of grant funding to support the upfront costs of developing and building low carbon hydrogen production projects.

As a further example, in 2019 the Netherlands set targets for 3GW to 4GW of electrolysis by 2030 with multi-billion- Euro funding support announced by the Netherlands government. The government is providing EUR 750 million of funding support for a "hydrogen backbone", retrofitting existing natural gas pipelines to transport hydrogen between five industrial clusters in the Netherlands, and at cross-border connection points. In May 2023, the Dutch government unveiled a EUR 28 billion climate package, which included EUR 7.5 billion for green hydrogen.

The Investment Adviser tracks deal flow in the hydrogen sector. So far in 2023, we have seen some £13 billion of industry investment in green hydrogen, which is a 380% increase compared to full year 2022 levels. Notably, the July 2023 IPO of Thyssenkrupp Nucera, a Germany electrolyser business, raised over EUR 500 million of fresh equity, with a valuation of some EUR 2.5 billion. In Saudi Arabia, the world's largest green hydrogen project, at NEOM, reached financial close, raising £6.6 billion for a 2+ GW project.

All of this underscores the positive industry outlook and supportive regulatory regimes for clean hydrogen. This improving outlook for clean hydrogen demand underpins the order books in many of the Company's investments, particularly in supply chain sectors such as electrolysers, fuel cells, storage and transportation businesses. Many of these businesses have world‑wide customer bases for their products, and are attracting investment from international financial and strategic investors.

We are tracking over 170 projects on line today around the world, totalling 800MW, then 13GW in over 140 projects that are under construction or advanced development, with investment in land, electrolysers, FEED studies. Some 4.5GW of this is under construction today, and a further 1,200GW in over 480 projects that have serious intent to build.

Investment portfolio

During the period, the Company has invested a total of £6.2 million into three existing Private Hydrogen Assets, and committed £2.6 million into its first investment in a private hydrogen project, the Thierbach project in Germany. Of this commitment, £1.9 million has been invested at 30 June 2023.

The Company holds £3 million in 15 listed hydrogen companies world-wide. These listed companies have been selected as having the best long term growth potential and attractive valuations. The first half of 2023 has seen general weakness in listed hydrogen companies, as a result of higher market interest rates, which has limited investor appetite for earlier stage growth themes.

Uninvested funds of £8.9 million are currently held in uncommitted cash and cash equivalents in the Company's Liquidity Reserve, ahead of investment.

The Investment Adviser believes that the performance of portfolio companies is in line with expectations. NAV has increased by 3.4% to £129.7 million in the first half of 2023. This has been driven by organic growth in private portfolio companies, with some offset from weaker performance from listed hydrogen companies, exchange rates and fund expenses.

Private portfolio companies generated some £52 million of revenues for the 12 months to Q2 2023, an increase of 170% from the 12 months to Q2 2022 on a pro-forma basis. This has been delivered by the conversion of strong order books into sales, particularly in supply chain and hydrogen distribution equipment companies. The Investment Adviser expects continued strong organic growth from the portfolio. In addition, the Investment Adviser anticipates follow-on funding rounds from new investors in portfolio companies at higher valuations, and exits from multiple portfolio positions via trade sales and IPOs over time.

Valuation

As set out in note 4 of the Financial Statements, the Investment Adviser has carried out fair market valuations of the Private Hydrogen Assets at 30 June 2023, which have been reviewed by the Valuation Committee, and the Directors have satisfied themselves as to the methodology used, the discount rates and key assumptions applied.

All Private Hydrogen Assets at 30 June 2023 have been valued using either the discounted cash flow ("DCF") methodology or a combination of the discounted cash flow methodology and the Price of Recent Investment methodology as described by the International Private Equity and Venture Capital Valuation 2018 ("IPEV") Guidelines.

Listed Hydrogen Assets are valued at fair value, which is the bid market price, or, if bid price is unavailable, last traded price on the relevant exchange.

Our approach to valuation remains consistent and unchanged:

· Valuations updated for all Private Hydrogen Assets on a quarterly basis, approved by the AIFM and Board

· The Private Hydrogen Assets are principally valued using either the DCF method, or a combination of the DCF method and the Price of Recent Investment. The valuations are also benchmarked against listed peer group valuations

· Discount rates are calculated using market parameters for each investment domicile. The portfolio average discount rate for 30 June 2023 was 13.7% compared with 13.0% at December 2022 and 12.4% at June 2022

· 30 June 2023 NAV was reduced by 5.1 pence per share compared to 31 December 2022, as a result of higher discount rates.

The Company notes that its NAV has been steadily increasing over the last twelve months. This has been driven by organic growth in the Company's private assets, despite headwinds from lower listed share prices in the portfolio and higher discount rates. By contrast, the share prices of listed hydrogen companies, which we track with the SOLGHYD index, have been volatile and declining since Q3 2021. This decline is due to market allocation away from early stage technology businesses as interest rates have risen, and a correction to the high valuations seen in the market in 2020-21. The Company's own share price has tracked this decline in listed hydrogen companies, and listed funds in general, despite the growth in NAV. Despite this, the Company assesses that the carrying value of its private assets is some 30% lower than listed hydrogen companies, based on comparative revenue multiples.

Listed Hydrogen Assets portfolio

The Company holds investments in 15 global hydrogen sector listed equities with an average market capitalisation of £1.5 billion with minimum market capitalisation of £100 million. The aggregate investment in these listed companies was £7.4 million at the time of investment. These companies are key players in the electrolysis, fuel cell and clean hydrogen projects sectors.

During the six months ended 30 June 2023, one listed holding has been sold at a small loss.

Post period end acquisition

In July 2023, the Company has made a follow-on investment of £1.0 million into NanoSUN.

Net assets

Net assets increased from £125.4 million at 31 December 2022 to £129.7 million at 30 June 2023. The increase is principally due to an uplift in the value of the Private Hydrogen Assets of £6.4 million.

The net assets of £129.7 million comprise £120.7 million portfolio value of investments, including the holding in the HydrogenOne Capital Growth Investments (1) LP ("Limited Partnership"), and the Company's cash balances of £8.6 million, and other net assets of £0.4 million.

The Limited Partnership's net assets of £117.7 million comprise £117.5 million portfolio value of investments, cash balances of £0.3 million, and other net liabilities of £0.1 million.

Cash

At 30 June 2023, the Group had a total cash balance of £8.9 million, including £8.6 million in the Company's balance sheet and £0.3 million in the Limited Partnership, which is included in the Company's balance sheet within 'investments held at fair value through profit or loss' (31 December 2022: £19.7 million).

The Company had cash and cash equivalents of £8.9 million, and £3.0 million of listed hydrogen companies at the end of the period, and remains well funded for its day-to-day activities.

Gain for period

The Company's total gain before tax for the period ended 30 June 2023 is £4.4 million, generating gains of 3.39 pence per Ordinary Share.

In the period to 30 June 2023, the gains on fair value of investments were £5.1 million.

The expenses included in the income statement for the year were £0.8 million, in line with expectations. These comprise £0.1 million Investment Adviser fees and £0.7 million operating expenses. The details on how the Investment Adviser fees are charged are as set out in note 5 to the financial statements.

Ongoing charges

The 'ongoing charges' ratio is an indicator of the costs incurred in the day-to-day management of the Company.

The ongoing charges percentage for the six-month period to 30 June 2023 was 2.62% (30 June 2022: 2.46%). The ongoing charges have been calculated, in accordance with AIC guidance, as annualised ongoing charges (i.e. excluding acquisition costs and other non-recurring items) divided by the average published undiluted Net Asset Value in the period. The ongoing charges percentage has been calculated on the consolidated basis and therefore takes into consideration the expenses of Limited Partnership as well as the Company.

Methodology

The greenhouse gas emissions have been calculated in accordance with the Greenhouse Gas Protocol equity share approach and presented in line with guidance from the EU Sustainable Finance Disclosure Regulation. This means that the aggregate of each portfolio company's scopes are presented (as opposed to being disclosed in the Fund's scope 3 category 15). Each portfolio company has been engaged during to develop a greenhouse gas inventory. This process includes the identification of appropriate data sources for each inventory item. Data has been collected, reviewed and processed to calculate the emissions by an external provider. In line with expectations there are limitations to data (gaps or quality), these are addressed in accordance with the Greenhouse Gas Protocol via the use of estimates and each portfolio company receives feedback on data quality based on relevance, completeness, availability, consistency, transparency and accuracy.

Estimates form a necessary part of the greenhouse gas emission process and emission factors are central to this. Primarily the UK Department for Environment Food and Rural Affairs ("DEFRA") emission factors have been used or, where more appropriate, the Intergovernmental Panel on Climate Change ("IPPC") emission factors can be relied upon. Both of these sources are recognised by the Greenhouse Gas Protocol.

Avoided emissions have been calculated on a consequential basis using the International Financial Institution Framework for a Harmonised Approach to Greenhouse Gas Accounting. The membership behind this approach includes the United Nations Climate Change Secretariat, the World Bank, the European Investment Bank, and many others constituting 25 financial institutions. This standard also produces and updates a data set on grid emissions for many countries, this has been used as a key input into the estimation process. In accordance with the framework, portfolio companies who provide products (e.g. fuel cells or electrolysers) take the expected lifetime emissions of those products as sold. During the year, no projects were operationally producing hydrogen yet as they are still under development, when they do the annual avoided emissions from the hydrogen produced will be reported.

* In the prior period one portfolio company that is pre-revenue actually recorded c.£16k of revenue which significantly impacted this metric, removing that outlier gives a comparable of 40KG/£m.

** The HY23 is more than double the FY22 because of an increase in sales from Elcogen. The sales from Sunfire have not been included in the HY23 as they could not provide data so these figures are expected to increase in future reporting periods.

Governance

Investment objective and policy

Investment objective

The Company's investment objective is to deliver an attractive level of capital growth by investing, directly or indirectly, in a diversified portfolio of hydrogen and complementary hydrogen focussed assets whilst integrating core ESG principles into its decision making and ownership process.

Investment policy

The Company will seek to achieve its investment objective through investment in a diversified portfolio of hydrogen and complementary hydrogen focussed assets, with an expected focus in developed markets in Europe, North America, the GCC and Asia Pacific, comprising:

i. assets that produce clean hydrogen;

ii. large scale energy storage assets;

iii. carbon capture, use and storage assets;

iv. hydrogen distribution infrastructure assets;

v. assets involved in hydrogen supply chains, such as electrolysers and fuel cells; and

vi. businesses that utilise hydrogen applications such as transport, power generation, feedstock and heat (together "Hydrogen Assets").

The Company intends to implement its investment policy through the acquisition of hydrogen and complementary hydrogen focussed assets.

Private Hydrogen Assets

The Company invests in unquoted Hydrogen Assets, which may be operational companies or hydrogen projects (completed or under construction) ("Private Hydrogen Assets"). Investments are expected to be mainly in the form of equity, although investments may be made by way of debt and/or convertible securities. The Company may acquire a mix of controlling and non-controlling interests in Private Hydrogen Assets, however the Company intends to invest principally in non-controlling positions (with suitable minority protection rights to, inter alia, ensure that the Private Hydrogen Assets are operated and managed in a manner that is consistent with the Company's investment policy).

Given the time frame required to fully maximise the value of an investment, the Company expects that investments in Private Hydrogen Assets will be held for the medium to long term, although short term disposals of assets cannot be ruled out in exceptional or opportunistic circumstances. The Company intends to re-invest the proceeds of disposals in accordance with the Company's investment policy.

The Company observes the following investment restrictions, assessed at the time of an investment, when making investments in Private Hydrogen Assets:

· no single Private Hydrogen Asset will account for more than 20 per cent. of Gross Asset Value;

· Private Hydrogen Assets located outside developed markets in Europe, North America, the GCC and Asia Pacific will account for no more than 20 per cent. of Gross Asset Value; and

· at the time of an investment, the aggregate value of the Company's investments in Private Hydrogen Assets under contract to any single Offtaker will not exceed 40 per cent. of Gross Asset Value.

The Company will initially acquire Private Hydrogen Assets via HydrogenOne Capital Growth Investments (1) LP (the 'HydrogenOne Partnership'), a wholly owned subsidiary undertaking of the Company structured as an English limited partnership which is controlled by the Company and advised by the Investment Adviser. The HydrogenOne Partnership's investment policy and restrictions are the same as the Company's investment policy and restrictions for Private Hydrogen Assets and cannot be changed without the Company's consent. In due course, the Company may acquire Private Hydrogen Assets directly or by way of holdings in special purpose vehicles or intermediate holding entities (including successor limited partnerships established on substantially the same terms as the HydrogenOne Partnership) or, if the Company is considered a 'feeder fund' under the Listing Rules, other undertakings advised by the Investment Adviser and, in such circumstances, the investment policy and restrictions will also be applied on a look-through basis and such undertaking(s) will also be managed in accordance with the Company's investment policy.

Listed Hydrogen Assets

The Company also invests in quoted or traded Hydrogen Assets, which will predominantly be equity securities but may also be corporate debt and/or other financial instruments ("Listed Hydrogen Assets"). The Company is free to invest in Listed Hydrogen Assets in any market or country with a market capitalisation (at the time of investment) of at least US$100 million. The Company's approach is to be a long-term investor and will not ordinarily adopt short-term trading strategies. As the allocation to Private Hydrogen Assets grows the Listed Hydrogen Assets are expected to include strategic equity holdings derived from the listing of operational companies within the Private Hydrogen Assets portfolio over time.

The Company observes the following investment restrictions, assessed at the time of an investment, when making investments in Listed Hydrogen Assets:

· no single Listed Hydrogen Asset will account for more than 3 per cent. of the Gross Asset Value;

· the portfolio of Listed Hydrogen Assets will typically comprise no fewer than 10 Listed Hydrogen Assets at times when the Company is substantially invested;

· each Listed Hydrogen Asset must derive at least 50 per cent. of revenues from hydrogen and/or related technologies; and

· once fully invested, the target allocation to Listed Hydrogen Assets will be approximately 10 per cent or less of Gross Asset Value, subject to a maximum allocation of 30 per cent of Gross Asset Value.

During the initial Private Hydrogen Asset investment period after a capital raise and/or a realisation of a Private Hydrogen Asset, the Company intends to hold the relevant net proceeds of such capital raise/realisation in cash (in accordance with the Company's cash management policy set out below) pending subsequent investment in Private Hydrogen Assets.

Investment restrictions

The Company, in addition to the investment restrictions set out above, comply with the following investment restrictions when investing in Hydrogen Assets:

· the Company will not conduct any trading activity which is significant in the context of the Company as a whole;

· the Company will, at all times, invest and manage its assets

i. in a way which is consistent with its object of spreading investment risk; and

ii. in accordance with its published investment policy;

· the Company will not invest in other UK listed closed-ended investment companies; and

· no investments will be made in companies or projects that generate revenues from the extraction or production of fossil fuels (mining, drilling or other such extraction of thermal coal, oil or gas deposits).

Compliance with the above restrictions is measured at the time of investment and non-compliance resulting from changes in the price or value of Hydrogen Assets following investment will not be considered as a breach of the investment policy or restrictions.

Borrowing policy

The Company may take on debt for general working capital purposes or to finance investments and/or acquisitions, provided that at the time of drawing down (or acquiring) any debt (including limited recourse debt), total debt will not exceed 25 per cent of the prevailing Gross Asset Value at the time of drawing down (or acquiring) such debt. For the avoidance of doubt, in calculating gearing, no account will be taken of any investments in Hydrogen Assets that are made by the Company by way of a debt investment.

Gearing may be employed at the level of a special purpose vehicle ("SPV") or any intermediate subsidiary undertaking of the Company (such as the HydrogenOne Partnership) or, if the Company is considered a 'feeder fund' under the Listing Rules, other undertakings advised by the Investment Adviser in which the Company has invested or the Company itself. The limits on debt shall apply on a consolidated and look-through basis across the Company, the SPV or any such intermediate holding entities (such as the HydrogenOne Partnership) or, if the Company is considered a 'feeder fund' under the Listing Rules, other undertakings advised by the Investment Adviser in which the Company has invested but intra-group debt will not be counted.

Gearing of one or more Hydrogen Assets in which the Company has a non-controlling interest will not count towards these borrowing restrictions. However, in such circumstances, the matter will be brought to the attention of the Board who will determine the appropriate course of action.

Currency and hedging policy

The Company has the ability to enter into hedging transactions for the purpose of efficient portfolio management. In particular, the Company may engage in currency, inflation, interest rates, energy prices and commodity prices hedging. Any such hedging transactions will not be undertaken for speculative purposes.

Cash management

The Company may hold cash on deposit and may invest in cash equivalent investments, which may include short-term investments in money market type funds ("Cash and Cash Equivalents").

There is no restriction on the amount of Cash and Cash Equivalents that the Company may hold and there may be times when it is appropriate for the Company to have a significant Cash and Cash Equivalents position. In particular, the Company anticipates holding cash to cover the near-term capital requirements of the Pipeline of Private Hydrogen Assets and in periods of high market volatility. For the avoidance of doubt, the restrictions set out above in relation to investing in UK listed closed-ended investment companies do not apply to money market type funds.

Interim management report

The Directors are required to provide an Interim Management Report in accordance with the Financial Conduct Authority ("FCA") Disclosure Guidance and Transparency Rules ("DTR").

The Directors consider that the Chair's Statement and the Investment Adviser's Report of this Half-yearly Financial Report, provide details of the important events which have occurred during the six months ended 30 June 2023 ("Period") and their impact on the financial statements. The statement on related party transactions and the Directors' Statement of Responsibility (below), the Chairman's Statement and the Investment Adviser's Report together constitute the Interim Management Report of the Company for the Period. The outlook for the Company for the remaining six months of the year ending 31 December 2023 is discussed in the Chairman's Statement and the Investment Adviser's Report.

Details of the Private and Listed Hydrogen Assets held at the Period end are provided above.

Principal risks and uncertainties

The principal risks and uncertainties facing the Company are summarised below:

Principal Risks and Uncertainties

Regulatory

Changes in political or environmental conditions in the hydrogen sector (for example, changes in government policy or support) could affect the Company's prospects.

Policy support

The technologies required to produce and use green hydrogen need policy support to underpin the scale needed to drive stand-alone cost competitiveness. Governments worldwide are showing such support today, but that may be volatile over the investment time horizon of the Company.

Power price

The income and value of the Company's investments may be affected by changes in the market prices of electricity and hydrogen, both current and expected. Risks include refinancing risk, exposure to interest rate risk due to fluctuations in the prevailing market rates, covenant breaches and possible enhanced loss on poor performing assets.

Operational

Initial pre-deal due diligence may not uncover all risks associated to a transaction. Investments are subject to operating and technical risks. While the Company will seek investments with creditworthy and appropriately insured counterparties who bear the majority of these risks, there can be no assurance that all risks can be mitigated.

In addition, the long-term profitability of hydrogen investments will be partly dependent upon the efficient operation and maintenance of the assets. Inefficiency, or limitations in the skills, experience or resources of operating companies, may reduce revenue. As a result, profitability of the Company may be impaired leading to reduced returns for Shareholders.

Performance

Underperforming investment or investment strategy can lead to underperformance to the Company's target return and ultimate investment objective.

Future acquisitions and capital raises

Ongoing capital raises are intended. The Company's share price trading at an excessive discount to its net asset value may mean it is difficult to raise further capital through share issues for both onward investment and the continued running and management of the Company.

Refinancing

The operational risks of the Company including market, counterparty, credit and liquidity risk. Extreme market volatility can disrupt capital raising process and ability to raise monies to repay a debt demand in full. Investments in Private Hydrogen Assets are illiquid in nature and may take a longer period of time to realise in order to fund the Company's operations or meet its expenses. The Company may be forced to sell liquid assets to meet its expenses at a time when valuations are low.

Service providers

Disruption to, or failure of the Company's Administrator or other parties to complete their role efficiently, on time and in line with expectation.

Portfolio valuation

Risk that portfolio asset valuations published do not represent the Fair Market Values in accordance with the accounting requirements. Investment valuations are based on modelling / financial projections for the relevant investments. Projections will primarily be based on the Investment Adviser's assessment and are only estimates of future results based on assumptions made at the time of the projection. Actual results may vary significantly from the projections, which may reduce the profitability of the Company leading to reduced returns to Shareholders. A further rise in interest rates will lead to an increase in the Discount Rate applied to the Private Hydrogen Assets' valuation, leading to a reduction in the Company's net asset value.

Key person

The Investment Adviser is a newly formed Company, with minimum employees. As such, there are significant Key Person risks at this time and should they become unavailable, this could have a negative impact on the Company's ability to achieve its investment objective.

Tax

Breaches of Section 1158 of the Corporation Tax Act could result in loss of investment trust status. Changes in tax legislation such as BEPS, WHT rules and structural requirements result in increased tax and resulting in a drop in returns from the Company's investments.

Political and associated economic risk

Exposure to Russia and/or Ukraine within the investment portfolio could lead to losses on investments.

The impact on the global equity markets, and hydrogen stocks in particular, of a prolonged downturn caused by the situation, could lead to reduced valuations of the Company.

The Company's Annual Report for the year ended 31 December 2022 contains more detail on the Company's principal risks and uncertainties, including the Board's ongoing process to identify, and where possible mitigate, emerging risks (pages 56 to 58). The Annual Report can be found on the Company's website at www.hydrogenonecapitalgrowthplc.com.

The Board is of the opinion that these principal risks are equally applicable to the remaining six months of the financial year as they were to the six months being reported on.

Related party transactions

Details of the investment management arrangements were provided in the Annual Report. There have been no changes to the related party transactions described in the Annual Report that could have a material effect on the financial position or performance of the Company. Amounts payable to the Investment Adviser and the Directors in the period are detailed in note 13 to the financial statements.

Going concern

This Half-yearly Financial Report has been prepared on a going concern basis. The Directors consider this the appropriate basis as they have a reasonable expectation that the Company and Group has adequate resources to continue in operational existence for at least twelve months from the date of this report.

In reaching this conclusion, the Directors considered the income and expense projections and the liquidity of the investment portfolio, and considered the impact to the Company and portfolio of investments from the economic conditions such as higher interest rates and inflationary pressures and market volatility arising from the ongoing war in Ukraine.

The Company and Group continue to meet day-to-day liquidity needs through its cash resources. The Company and Group had unrestricted cash of £8.6 million (31 December 2022: £18.2 million) as well as £3.0 million in Listed Hydrogen Assets at 30 June 2023 (31 December 2022: £3.7 million). The Company and Group's net assets at 30 June 2023 were £129.7 million (31 December 2022: £125.4 million) and total expenses for the period ended 30 June 2023 were £3.4 million (30 June 2022: £2.7 million), which represented approximately 2.6% (30 June 2022: 2.5%) of the average net assets value of the Company in the six months to 30 June 2023 of £128.0 million (30 June 2022: £110.7 million).

Following the declaration of the Company's Net Asset Value as at the 30 June 2023 on the 7 August 2023, the Company's share price was 54.4p representing a 46.0% discount to the Net Asset Value (31 December 2022: discount of 18.5%).

The Directors also recognise that the continuation of the Company is subject to the approval of shareholders at the Annual General Meeting ("AGM") in 2026, and every fifth AGM thereafter. The Board has considered the long-term prospects of the Company and has no reason to believe that the continuation vote will fail.

Based on the foregoing, the Directors have adopted the going concern basis in preparing the Financial Statements. The Directors have a reasonable expectation that the Company and Group have adequate operational resources to continue in operational existence for at least twelve months from the date of approval of these Financial Statements.

Notes to the financial statements

1. General information

Company information

HydrogenOne Capital Growth plc (the "Company" or "Parent") was incorporated in England and Wales on 16 April 2021 with registered number 13340859 as a public company limited by shares and is an investment company within the terms of Section 833 of the Companies Act 2006 (the "Act"). The Company is listed and began trading on the Main Market of the London Stock Exchange and was admitted to the premium segment of the Official List on 30 July 2021 (the "IPO"). The Company has applied for and been accepted as an approved investment trust under sections 1158 and 1159 of the Corporation Tax Act 2010 and Part 2 Chapter 1 of Statutory Instrument 2011/2999.

FundRock Management Company (Guernsey) Limited acts as the Company's Alternative Investment Fund Manager ("AIFM").

Apex Listed Companies Services (UK) Limited (the "Company Secretary and Administrator") provides administrative and company secretarial services to the Company.

The Company's Investment Adviser is HydrogenOne Capital LLP.

The Company's registered office is 6th Floor, 125 London Wall, London, EC2Y 5AS.

Investment objective

The Company's investment objective is to deliver an attractive level of capital growth by investing, directly or indirectly, in a diversified portfolio of hydrogen and complementary hydrogen focussed assets whilst integrating core environmental, social and governance ("ESG") principles into its decision making and ownership process.

Company structure

The Company makes its investment in unquoted Hydrogen Assets ("Private Hydrogen Assets") through HydrogenOne Capital Growth Investments (1) LP (the "Limited Partnership"), in which the Company is the sole Limited Partner. The Limited Partnership is registered as a private fund limited partnership in England and Wales under the Limited Partnerships Act 1907 with registered number LP021814. The Limited Partnership has been established pursuant to a Limited Partnership Agreement dated 5 July 2021 as amended and restated on 26 November 2021 (the "Limited Partnership Agreement") in order to make investments pursuant to the investment policy of the Limited Partnership. The Limited Partnership's investment policy and restrictions are consistent with the Company's investment policy and restrictions for Private Hydrogen Assets.

The General Partner of the Limited Partnership is HydrogenOne Capital Growth (GP) Limited (the "General Partner"), a wholly owned subsidiary of the Company. The General Partner was incorporated in England and Wales on 19 May 2021 with registered number 13407844. The General Partner undertakes the responsibility for the management, operation and administration of the business and affairs of the Limited Partnership. The General Partner's Profit Share for each accounting period shall be an amount equal to 1.5% per annum of the prevailing NAV of the Limited Partnership, which shall be allocated to the General Partner as a first charge on the profits of the Limited Partnership. For so long as the Company is the sole Limited Partner, the General Partner's Profit Share shall be allocated and distributed to the Company rather than the General Partner.

The carried interest partner of the Limited Partnership is HydrogenOne Capital Growth (Carried Interest) LP (the "Carried Interest Partner") which, in certain circumstances, will receive carried interest on the realisation of Private Hydrogen Assets by the Limited Partnership. The Carried Interest Partner has been set up for the benefit of the principals of the Investment Adviser.

Private Hydrogen Assets

The Company invests via the Limited Partnership in Private Hydrogen Assets, which may be operational companies or hydrogen projects. Investments are mainly in the form of equity, although investments may be made by way of debt and/or convertible securities. The Company may acquire a mix of controlling and non-controlling interests in Private Hydrogen Assets, however the Company invests principally in non-controlling positions (with suitable minority protection rights to, inter alia, ensure that the Private Hydrogen Assets are operated and managed in a manner that is consistent with the Company's investment policy).

The Company acquires Private Hydrogen Assets via the Limited Partnership. In due course, the Company may acquire Private Hydrogen Assets directly or by way of holdings in special purpose vehicles or intermediate holding entities (including successor limited partnerships established on substantially the same terms as the Limited Partnership) or, if the Company is considered a 'feeder fund' under the Listing Rules, other undertakings advised by the Investment Adviser and, in such circumstances, the investment policy and restrictions will also be applied on a look-through basis and such undertaking(s) will also be managed in accordance with the Company's investment policy.

Listed Hydrogen Assets

The Company also invests directly in quoted or traded Hydrogen Assets, which are predominantly equity securities but may also be corporate debt and/or other financial instruments ("Listed Hydrogen Assets"). The Company has the ability to invest in Listed Hydrogen Assets in any market or country with a market capitalisation (at the time of investment) of at least US$100 million. The Company's approach is to be a long-term investor and will not ordinarily adopt short-term trading strategies.

Liquidity reserve

During the initial Private Hydrogen Asset investment period after a capital raise and/or a realisation of a Private Hydrogen Asset, the Company intends to allocate the relevant net proceeds of such capital raise/realisation to cash (in accordance with the Company's cash management policy) and/or additional Listed Hydrogen Assets and related businesses pending subsequent investment in Private Hydrogen Assets (the ''Liquidity Reserve'').

The Company anticipates holding cash to cover the near-term capital requirements of the pipeline of Private Hydrogen Assets and in periods of high market volatility.

2. Basis of preparation and accounting policies

The principal accounting policies are set out below:

Reporting entity

These Parent and Consolidated Financial Statements (the "Financial Statements") present the results of both the Parent; and the Parent and the General Partner (together referred to as the "Group").

As at 30 June 2023, the statement of financial position of the General Partner consisted of issued share capital and corresponding share capital receivable in the amount of £1. The General Partner had no income, expenditure or cash flows for the period.

Due to the immaterial balances of the General Partner there is no material difference between the results of the Parent and the results of the Group. As a result, the Financial Statements as presented represent both the Parent's and the Group's financial position, performance, and cash flows.

Basis of accounting

The Financial Statements have been prepared in accordance with UK-adopted international accounting standards ("IFRS") and the applicable legal requirements of the Companies Act 2006.

The Financial Statements have also been prepared as far as is relevant and applicable to the Company and Group in accordance with the Statement of Recommended Practice ("SORP") issued by the Association of Investment Companies ("AIC") in July 2022.

The Financial Statements are prepared on the historical cost basis, except for the revaluation of financial instruments measured at fair value through profit or loss.

Fair value is the price that would be received on sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, regardless of whether that price is directly observable or estimated using another valuation technique. In estimating the fair value of an asset or liability, the Company and Group take into account the characteristics of the asset or liability if market participants would take those characteristics into account when pricing the asset or liability at the measurement date. Fair value for measurement and/or disclosure purposes in these Financial Statements is determined on such a basis.

The Financial Statements are presented in Pounds Sterling because that is the currency of the primary economic environment in which the Company and Group operate.

The accounting policies applied in these Financial Statements are consistent with those applied in the last Annual Audited Financial Statements for the year ended 31 December 2022. These condensed financial statements do not include all information and disclosures required in the annual financial statements and should be read in conjunction with the Company's annual financial statements as of 31 December 2022. The audited annual accounts for the year ended 31 December 2022 have been delivered to Companies House and the audit report thereon was unqualified.

Going concern

Having reassessed the principal risks, the Directors considered it appropriate to adopt the going concern basis of accounting in preparing these Financial Statements. Details of the Directors' assessment of the going concern status of the Company and Group, which considered the adequacy of resources and the impacts of economic conditions and market volatility arising from the war in Ukraine are given above.

Critical accounting judgements, estimates and assumptions

There have been no changes to the critical accounting judgements estimates and assumptions from those applied in the Company's Audited Annual Financial Statements for the year ended 31 December 2022.

Comparatives

Comparative information is included for the six months ended 30 June 2022 and as at 31 December 2022.

3. Segmental reporting

The Board has considered the requirements of IFRS 8 - 'Operating Segments'. The Company has entered into an Investment Advisory Agreement with the Investment Adviser under which the Investment Adviser is responsible for the management of the Company's investment portfolio, subject to the overall supervision of the Board of Directors. Subject to its terms and conditions, the Investment Advisory Agreement requires the Investment Adviser to manage the Company's investment portfolio in accordance with the Company's investment guidelines as in effect from time to time, including the authority to purchase and sell investments and to carry out other actions as appropriate to give effect thereto. However, the Board retains full responsibility to ensure that the Investment Adviser adheres to its mandate. Moreover, the Board is fully responsible for the appointment and/or removal of the Investment Adviser. Accordingly, the Board is deemed to be the 'Chief Operating Decision Maker' of the Company.

The Directors are of the opinion that the Company is engaged in a single segment of business being investment into the hydrogen focused investments. Segment information is measured on the same basis as that used in the preparation of the Company's Financial Statements.

Under IFRS 13 'Fair Value Measurement', an entity is required to classify investments using a fair value hierarchy that reflects the significance of the inputs used in making the measurement decision.

The following shows the analysis of financial assets recognised at fair value based on:

Level 1

The unadjusted quoted price in an active market for identical assets or liabilities that the entity can access at the measurement date.

Level 2

Inputs other than quoted prices included within Level 1 that are observable (i.e. developed using market data) for the asset or liability, either directly or indirectly.

Level 3

Inputs are unobservable (i.e. for which market data is unavailable) for the asset or liability.

Transfers between levels of the fair value hierarchy are recognised as at the end of the reporting period during which the change has occurred. There have been no transfers between levels during the period ended 30 June 2023. (December 2022: no transfers).

The classification of the Company and Group's investments held at fair value through profit or loss is detailed in the table below:

	30 June 2023
	Level 1		Level 2		Level 3		Total
	£'000		£'000		£'000		£'000

The following table shows the Directors best estimate of the sensitivity of the Level 3 Private Hydrogen Assets to changes in the principle unobservable input, with all other variables held constant.

	Effect on fair value of investments £'000
Unobservable input	Possible reasonable change in input	30 June 2023	31 December 2022
Discount rates applied in full DCF valuation	+1%	(14,716)	(6,515)
	-1%	18,133	7,815
Weighting between Price of Recent Investment and full DCF valuation	plus one calendar quarter of tapering from Price of Recent Investment to full DCF valuation	(975)	(324)
	minus one calendar quarter of tapering from Price of Recent Investment to full DCF valuation	2,926	286

The European Central Bank ('ECB') and the Bank of England ('BOE') base rates at 30 June 2023 were 4.0% and 5.0% respectively (31 December 2022: 2.5% and 3.5% respectively). We anticipate that the terminal base rate hikes (based on independent research) could reach 4.5% for ECB and 5.5% for BOE. As such, we have performed sensitivities of +/- 1% on the discount rate assumptions.

The valuations are weighted towards the full DCF valuation based on the time since the price of recent investment until the full DCF valuation is applied (typically the valuations are tapered from the price of recent investment to the full DCF valuation over four calendar quarters after the price of recent investment). Accordingly, we have applied a sensitivity of +/- one calendar quarter of this weighting as this is deemed the most likely period by which the tapering may be delayed or brought forward.

For those investments that have been fair valued using the price of a recent investment based on unadjusted third-party pricing information, the Company is not required to disclose any quantitative information regarding the unobservable inputs as they have not been developed by the Company and are not reasonably available to the Company.

At 30 June 2023 an amount of £13,000 was receivable from the Investment Adviser in respect of the Investment Adviser fee (31 December 2022: 12,554 payable). Additionally, the Company agreed with the Investment Adviser that the costs and expenses of the IPO would be capped at 2% of the gross proceeds received, with any cost above this amount to be paid by the Investment Adviser by way of rebate of its adviser fee. At 30 June 2023, £74,322 in respect of excess issue costs is due to be received from the Investment Adviser (31 December 2022: £111,432).

Investment Adviser fee

The Company has entered into an Investment Adviser Agreement dated 5 July 2021 between the Company, the AIFM and the Investment Adviser (the "Investment Adviser Agreement"), pursuant to which the Investment Adviser has been given responsibility for investment advisory services in respect of any Private Hydrogen Assets the Company invests in directly and the Listed Hydrogen Assets (including Listed Hydrogen Assets forming part of the Liquidity Reserve and uninvested cash) in accordance with the Company's investment policy, subject to the overall control and supervision of the Board and the AIFM.

Under the Investment Adviser Agreement, the Investment Adviser receives from the Company, quarterly in advance, an advisory fee equal to:

i. 1.0% of the Net Asset Value per annum of the Listed Hydrogen Assets up to £100 million:

ii. 0.8% of the Net Asset Value per annum of the Listed Hydrogen Assets from £100 million (save that the Investment Adviser has agreed to reduce this fee to 0.5% in respect of the Liquidity Reserve pending its re-investment in Private Hydrogen Assets for 18 months following Admission, being to and including 30 January 2023);

iii. 1.5% of the Net Asset Value per annum of any Private Hydrogen Assets held by the Company directly (i.e. not held by the Limited Partnership or any other undertaking advised by the Investment Adviser where the Investment Adviser is receiving a separate advisory fee); and

iv. for so long as the Company is not considered a 'feeder fund' for the purposes of the Listing Rules, 1.5% per annum of the Net Asset Value of the Private Hydrogen Assets held by the Limited Partnership.

The Limited Partnership has entered into a Limited Partnership Investment Adviser Agreement dated 5 July 2021 (the "Limited Partnership Investment Adviser Agreement") between the General Partner (in its capacity as general partner of the Limited Partnership), the AIFM and the Investment Adviser, pursuant to which the Investment Adviser has been given responsibility for investment advisory services in respect of the Private Hydrogen Assets in accordance with the investment policy of the Limited Partnership, subject to the overall control and supervision of the General Partner and the AIFM.

Under the Limited Partnership Investment Adviser Agreement, the Investment Adviser, if the Company was considered a 'feeder fund' for the purposes of the Listing Rules by virtue of additional investors co-investing via the Limited Partnership in the future, shall receive from the Limited Partnership an advisory fee equal to 1.5% per annum of the Net Asset Value of the Private Hydrogen Assets held by the Limited Partnership, payable quarterly in advance. Advisory fees paid or payable by the Limited Partnership are reflected through the NAV of the Limited Partnership.

No performance fee is paid or payable to the Investment Adviser under either the Investment Adviser Agreement or the Limited Partnership Investment Adviser Agreement but the principals of the Investment Adviser are, subject to certain performance conditions being met, entitled to carried interest fees from the Limited Partnership. Refer to 'Carried Interest Partner Fees' section below.

Carried Interest Partner Fees

Pursuant to the terms of the Limited Partnership Agreement dated 5 July 2021 as amended and restated on 26 November 2021 (the "Limited Partnership Agreement"), the Carried Interest Partner is, subject to the limited partners of the Limited Partnership receiving an aggregate annualised 8% realised return (i.e. the Company and, in due course, any additional co-investors), entitled to a carried interest fee in respect of the performance of the Private Hydrogen Assets.

Subject to certain exceptions, the Carried Interest Partner will receive, in aggregate, 15% of the net realised cash profits from the Private Hydrogen Assets held by the Limited Partnership once the limited partners of the Limited Partnership (i.e. the Company and, in due course, any additional co-investors) have received an aggregate annualised 8% realised return. This return is subject to a 'catch-up' provision in Carried Interest Partner's favour. Any realised or unrealised carried interest fee paid or payable to the Carried Interest Partner is reflected through the NAV of the Limited Partnership. During the period carried interest fees of £116,065 (31 December 2022: £nil) were accrued as payable to the Carried Interest Partner.

20% of any carried interest received (net of tax) will be used by the principals of the Investment Adviser to acquire Ordinary Shares in the market. Any such acquired shares will be subject to a 12-month lock-up from the date of purchase.

General Partner's priority profit share

Under the Limited Partnership Agreement, the General Partner of the Limited Partnership shall be entitled to a General Partner's Profit Share ("GPS"). The GPS for each accounting period shall be an amount equal to 1.5% of the prevailing NAV of the Limited Partnership. For so long as the Company is the sole limited partner of the Limited Partnership, the GPS shall be distributed to the Company rather than the General Partner. The Company is currently the sole limited partner of the Limited Partnership. Therefore, under the Investment Adviser Agreement, the investment adviser fee in relation to the Private Hydrogen Assets held by the Limited Partnership is settled by the Company which for the period totalled £803,722 (30 June 2022: £444,856). During the period the Limited Partnership did not call any GPS from the Company as the net effect of the calling and distributing GPS from/to the Company is £nil (30 June 2022: £nil).
