- Topsoe's SOEC technology will power Project Starling, producing 25,000 metric tons of e-SAF annually.
- Construction is planned for 2028, with operations expected by 2031, pending final investment decision.
- Project Starling received a £6 million grant from the UK Government's Advanced Fuel Fund in July 2025.
- The facility aims for an 89% reduction in lifecycle emissions compared to fossil jet fuel.
Project Overview
Topsoe has been selected to provide its Solid Oxide Electrolyzer Cell (SOEC) technology for Carbon Neutral Fuels' e-SAF project, known as Project Starling, in Workington, UK. The facility aims to produce 25,000 metric tons of sustainable aviation fuel annually.
Timeline and Operations
Construction of the plant is scheduled for 2028, with operations expected to commence in 2031, contingent on the final investment decision. The project is currently in the Front-End Engineering and Design (FEED) stage.
Government Support
In July 2025, Project Starling received a £6 million grant from the UK Government's Advanced Fuel Fund, marking the largest award in the fund's third window. This initiative supports the UK's SAF Mandate and Jet Zero Strategy.
Environmental Impact
Once operational, the facility is projected to achieve an 89% reduction in lifecycle emissions compared to traditional fossil jet fuel, significantly contributing to the UK's climate goals.
Technology and Production
Topsoe's SOEC technology, known for its high efficiency, will be used to produce green hydrogen, a key component in e-SAF production. The electrolyzer stacks will be manufactured in Herning, Denmark, with first deliveries expected in 2028, pending the final investment decision.
