SEKISUI CHEMICAL and Velocys have signed a memorandum of understanding (MoU) to develop new production technology for electro-Sustainable Aviation Fuel (e-SAF) using captured CO₂. The collaboration combines SEKISUI’s proprietary CO₂→CO chemical looping process, which achieves high reaction yields of over 90%, with Velocys’ Fischer–Tropsch (FT) microchannel reactor technology, which delivers six to ten times higher productivity than conventional FT systems.

The partners aim to establish an efficient pathway for producing e-SAF from CO₂ and renewable hydrogen, addressing the growing demand for sustainable fuels in aviation. With aviation responsible for around 2.6% of global CO₂ emissions and SAF seen as essential to meeting decarbonisation targets, this technology could play a key role in reducing the industry’s climate impact.

By leveraging SEKISUI’s expertise in carbon capture and utilisation (CCU) and Velocys’ two decades of FT development, the partnership seeks to advance scalable, CO₂-derived e-SAF solutions that support both aviation’s energy transition and broader climate goals.
