SeaO₂, in partnership with TU Delft, the University of Twente, and NERA, has secured €1.64 million from the TKI Energy and Industry programme to develop a decentralised, fully integrated process for producing sustainable aviation fuel (e-SAF) using seawater, renewable electricity, and captured CO₂.

The project aims to create a local and flexible alternative to fossil- or biomass-based fuels by combining innovations in CO₂ capture, electrochemical conversion, and catalysis. The system will extract CO₂ from seawater and use renewable electricity to produce hydrogen, which will then be combined with CO₂ to generate the alcohols and olefins needed for e-SAF.

Alongside technical development, the partners will carry out a techno-economic analysis to benchmark the system’s cost-effectiveness and scalability against conventional kerosene. The project marks a step toward localised e-fuel production with minimal environmental impact.
