The UK’s pioneering Project Starling reaches a key engineering milestone, bringing closer its goal of producing over 25,000 tonnes of low-carbon aviation fuel annually by 2031, marking a significant step in domestic sustainable aviation fuel development.
Carbon Neutral Fuels, io consulting and Mission Zero Technologies have taken a further step towards what they say could become one of the UK’s most significant synthetic aviation fuel projects, after completing the FEL3A stage for Project Starling.
The Workington-based scheme is being developed as a first-of-its-kind eSAF plant designed to make synthetic hydrocarbons from captured CO₂, water and low-carbon electricity. According to the project partners, the latest phase has brought together licensor technology packages into a single integrated design, alongside safety studies and a detailed 3D model of the facility. That, they say, supports a Class 3 cost estimate and gives the project a firmer basis for the next stage of development.
Project Starling is being positioned as a commercial-scale Power-to-Liquids facility with a planned output of more than 25,000 tonnes of fuel a year by 2031. Carbon Neutral Fuels says that would be enough to cover around 35% to 40% of the UK’s mandated Power-to-Liquid SAF supply in 2030, while cutting greenhouse gas emissions by about 95% compared with conventional Jet A-1.
The project has already benefited from support through the UK Department for Transport’s Advanced Fuels Fund, which backs first-of-a-kind commercial and demonstration-scale fuel projects. Government material on the fund shows it is aimed at technologies that can deliver substantial lifecycle emissions reductions, helping to move advanced fuels from concept towards deployment.
io consulting said the earlier FEL2 pre-FEED phase focused on technology selection, system integration and cost modelling, laying the groundwork for the more detailed definition now completed. In practical terms, the move from concept into a more mature engineering package matters because capital efficiency, constructability and execution planning often determine whether industrial decarbonisation projects progress beyond the drawing board.
For Mission Zero Technologies, the project is also another application for direct air capture in a fuel value chain rather than in carbon storage alone. The company has been building a portfolio of projects that use atmospheric CO₂ as a feedstock, and its role in Project Starling underlines how DAC is increasingly being tied to synthetic fuels, not just to removals markets.
Stephanie Ng, project director at Carbon Neutral Fuels, said completing FEL3A gives the team greater confidence in the project’s definition and delivery route. Richard Dyson, chief executive of io consulting, said the stage is where projects move beyond concept and into something that can be delivered, while Nicholas Chadwick, chief executive of Mission Zero Technologies, said the milestone reflects the growing role of DAC in enabling scalable low-carbon fuels.
The wider significance of Project Starling lies in what it represents for the UK’s eSAF ambitions. Synthetic aviation fuel remains a difficult proposition commercially, with high power demand, complex process integration and heavy upfront capital requirements. But projects such as Starling suggest the sector is beginning to move through the engineering stages that will be needed if the UK is to build a domestic supply chain for lower-carbon aviation fuels rather than rely solely on imports.
