Carbon Neutral Fuels (CNF) has unveiled ‘FlexSAF’, a flexible plant design that enables the production of both eSAF and advanced bioSAF at a single facility.
Debuting at CNF’s flagship Project Starling site in Workington, West Cumbria, the FlexSAF design’s higher output contributes to solving the SAF supply gap, where industry professionals are concerned that statutory UK and EU SAF mandates are rising faster than dedicated production capacity can be built.
By integrating dual feedstock pathways (eSAF from biogenic CO2, water, renewable electricity, and advanced bioSAF from biomethane), FlexSAF gives Project Starling a more diverse feedstock base. Both pathways feed into a single, shared Fischer-Tropsch (FT) synthesis and upgrading line, increasing SAF target output to approximately 42,000 tonnes per year. This shared infrastructure is expected to significantly lower the production cost per tonne of fuel while offering flexibility within plant parameters to adjust the production mix in response to feedstock availability and market demand.
