Independent testing demonstrates biofuel benefits
(Aquis Stock Exchange: SNOX, OTCQX: SNOXF)
Sulnox, the greentech company delivering lower fuel costs and emissions with zero capex, is pleased to announce the results of an independent laboratory evaluation of Sulnox Eco™ by a leading marine fuels testing organisation.
The study evaluated Sulnox EcoTM across the range of marine fuels included in the expanded ISO8217 (the international marine fuel standard), building on Sulnox's previously announced ISO8217 certification. The evaluation covered fossil fuels and marine biofuels, including FAME blends, neat FAME (B100) and HVO.
Consistent with the earlier certification, testing confirmed full compatibility across all fuels tested, while also demonstrating measurable performance benefits in key biofuel chemistries.
This is particularly relevant as marine biofuels are increasingly adopted across the industry but are known to introduce fuel-specific challenges, including:
· Reduced lubricity - meaning the fuel provides less natural lubrication for pumps and injectors, which can increase wear on engine components
· Lower oxidation stability - meaning the fuel can degrade more readily during storage, potentially affecting fuel quality over time
· Increased corrosion risk - meaning fuels can promote corrosive conditions that may damage metal surfaces within fuel systems
Marine biofuel consumption currently represents c.1-2 million tonnes per year (around 1-2% of global marine fuel demand), but industry forecasts suggest this could grow to 15-30 million tonnes annually by 2030 as decarbonisation regulations accelerate adoption (Source: IEA).
As adoption accelerates, the independent testing demonstrated that Sulnox Eco can mitigate these challenges while remaining fully compatible with both renewable and conventional marine fuels, including:
· c.28% improvement in lubricity in HVO - helping restore fuel lubrication and support engine component protection
· 3× improvement in oxidative stability in neat B100 (FAME) - supporting improved storage stability of biofuels
· "Technically significant" reduction in steel corrosion ('pitting') in untreated B100 - reducing corrosion risk in fuel systems
The testing laboratory commented:
"Sulnox Eco provides measurable benefits for specific fuel chemistries while maintaining overall fuel compatibility."
Ben Richardson, CEO of Sulnox, said:
"Independent verification by a leading marine fuels laboratory confirms that Sulnox Eco remains fully compatible with the latest ISO marine fuel standard while also demonstrating measurable benefits for emerging biofuels.
As renewable fuels become an established part of the global fuel mix, these findings reinforce Sulnox Eco's position as a low-risk drop-in solution capable of supporting both conventional and renewable fuels. Importantly, this compatibility also opens up potential opportunities for integration within larger-scale blending and bunker supply operations across the fuel market."
