When did Sulnox announce the independent testing results for Sulnox Eco™?

Sulnox announced the results on 2026-03-16. The announcement covered an independent evaluation of Sulnox Eco™ across marine fuels included in the expanded ISO8217 standard.

What fuels did the Sulnox Eco™ evaluation cover?

The evaluation covered fossil fuels and marine biofuels, including FAME blends, neat FAME (B100) and HVO. Sulnox said the testing confirmed compatibility across all fuels tested.

What did the Sulnox Eco™ testing show about fuel compatibility?

The testing confirmed full compatibility across all fuels tested, consistent with Sulnox’s previously announced ISO8217 certification. Ben Richardson, CEO of Sulnox, said the results confirmed compatibility with the latest ISO marine fuel standard.

What lubricity improvement did Sulnox Eco™ demonstrate in HVO?

Sulnox reported a c.28% improvement in lubricity in HVO. The company said this could help restore fuel lubrication and support engine component protection.

How did Sulnox Eco™ affect oxidative stability in neat B100?

Sulnox reported a 3× improvement in oxidative stability in neat B100 (FAME). The company said this supports improved storage stability of biofuels.

What did the testing show about corrosion in untreated B100?

The testing laboratory reported a “Technically significant” reduction in steel corrosion, described as “pitting”, in untreated B100. Sulnox said this reduces corrosion risk in fuel systems.

What fuel-specific challenges associated with marine biofuels did Sulnox identify?

Sulnox identified reduced lubricity, lower oxidation stability and increased corrosion risk as fuel-specific challenges associated with marine biofuels. The company said these issues can increase wear on pumps and injectors, affect fuel quality during storage and damage metal surfaces within fuel systems.

How much marine biofuel is currently consumed, according to Sulnox?

Sulnox said marine biofuel consumption currently represents c.1–2 million tonnes per year, around 1–2% of global marine fuel demand. The announcement attributed these figures to the IEA.

What growth in marine biofuel use does Sulnox cite for 2030?

Sulnox said industry forecasts suggest marine biofuel consumption could grow to 15–30 million tonnes annually by 2030 as decarbonisation regulations accelerate adoption. The statement attributes this forecast to industry forecasts and cites the IEA as its source.

What did the testing laboratory say about Sulnox Eco™?

The testing laboratory said: “Sulnox Eco provides measurable benefits for specific fuel chemistries while maintaining overall fuel compatibility.”

What did Sulnox CEO Ben Richardson say about the testing results?

Ben Richardson said the independent testing confirmed that Sulnox Eco™ remains fully compatible with the latest ISO marine fuel standard while demonstrating measurable benefits for emerging biofuels. He also said the compatibility opens up potential opportunities for integration within larger-scale blending and bunker supply operations across the fuel market.

What does Sulnox say the testing could mean for the use of Sulnox Eco™?

Sulnox CEO Ben Richardson said the findings support Sulnox Eco™ as a drop-in solution for conventional and renewable fuels. He also said the compatibility opens up potential opportunities for integration within larger-scale blending and bunker supply operations across the fuel market.

Announcement Summary

Sulnox announced independent laboratory results for Sulnox Eco™ across fossil fuels and marine biofuels.

The evaluation covered fuels in expanded ISO8217, the international marine fuel standard, including FAME blends, neat FAME (B100), and HVO.
Testing confirmed full compatibility across all fuels tested, consistent with Sulnox’s previously announced ISO8217 certification.
In HVO, testing found a c.28% improvement in lubricity, supporting lubrication and engine-component protection.
In neat B100 (FAME), testing found a 3× improvement in oxidative stability, supporting improved storage stability of biofuels.

In untreated B100, testing characterized the reduction in steel corrosion, or pitting, as technically significant.
