Carbon Neutral Fuels adds bio-SAF capability to UK green hydrogen plant, lifting output to 42,000 tonnes

Carbon Neutral Fuels (CNF) plans to expand its Project Starling SAF facility in Workington, UK, to produce both e-SAF from green hydrogen and bio-SAF from biomethane. The company says the updated FlexSAF design will raise annual fuel output from 25,000 to 42,000 tonnes, with first fuel production targeted for late 2031. Planning submission is expected in spring 2028, and the project has secured £6m from the UK Advanced Fuels Fund but has not yet reached final investment decision. The plant will use synthesis technology from Johnson Matthey and Honeywell, with green hydrogen supplied by 120MW of Topsoe solid oxide electrolysers. The flexible design lets CNF shift between feedstocks based on availability and market demand. This comes as the UK prepares for a 2030 mandate requiring 10% sustainable jet fuel, though questions remain over whether green hydrogen-based fuels will be available in time to meet the quota.

CNF is expanding Project Starling in Workington to make both e-SAF and bio-SAF. Output goes from 25,000 to 42,000 tonnes a year. Still no FID, planning submission in spring 2028, first fuel late 2031. UK SAF mandate pressure is building.

Adding biomethane feedstock to the same plant makes sense from a risk standpoint. You can run on whichever input is cheaper or available. But the 70% output jump depends on bio-SAF pathways clearing certification, not just engineering. Worth watching the RFNBO rules here.

120MW of SOEC electrolysis is a big build. FID is still pending and first fuel is late 2031. That timeline is tight for a 2030 mandate. Would like to know how much of the 42,000 tonnes is e-SAF versus bio-SAF, since the feedstock and electricity inputs are very different.

The HEFA cap question is the real story here. If the government loosens it, that weakens the signal for e-SAF projects like this one. If it keeps it, CNF gets a clearer market, but only if green hydrogen actually shows up at scale. The plant's flexibility is a hedge, not a solution.
