                                 ITM Power plc

                            ('ITM' or 'the Company')

                             Key US Patent Granted

           ITM Power's Fundamental Material Patent granted in the USA

ITM Power plc (AIM: ITM) is pleased to announce that on 15 January 2008 it has
been granted a patent for its fundamental materials from the US Patent Office
(Patent No: US 7,318,972 B2).

The patent application, which covers both the unique crosslinked hydrophilic
ionic materials and the novel production process, has been identified as two
separate inventions. Consequently, the Company has decided to allow the patent
examination process to proceed under the US 'divisional process' which offers
the possibility of achieving two independent patents from the one original
application. The divisional application covering the novel 'in-situ' production
process is now under review.

Jim Heathcote, CEO ITM Power, said:

'We are delighted to be granted the US patent covering our new class of
ionically conducting materials and we look forward to updating shareholders on
the progress with the second patent covering the low cost manufacturing process.
When granted, two patents will significantly enhance the Company's portfolio of
intellectual property.'

Notes to the Editors:

ITM Power is a developer of low-cost hydrogen technologies. The Company has
developed new materials and processes that dramatically reduce the cost of fuel
cells and electrolysers. The patented membrane materials used in the devices
have higher performance and are 1% of the cost of the industry standard
materials.

Electrolysers work by converting water and electricity into hydrogen and oxygen.
The hydrogen produced can be used as a replacement for fossil fuels and
facilitate zero carbon housing and pollution free motoring.

ITM Power was founded in 2000 and floated on the London Stock Exchange's
Alternative Investment Market in June 2004.
