Topsoe has been chosen to deliver advanced Solid Oxide Electrolyser Cell (SOEC) technology, consuming 120MW green power for Carbon Neutral Fuels’ e-SAF (Sustainable Aviation Fuel) project called Project Starling in Workington, UK.

The plant is expected to produce 25,000 metric tons of e-SAF per year. Construction is planned for 2028 with operations expected in 2031 pending final investment decision.

The project was the largest e-fuels award of the UK Government’s third Advanced Fuels Fund granted in July 2025, directly delivering on the UK’s SAF Mandate.
