Researchers at the Karlsruhe Institute of Technology (KIT) have made significant progress in the field of sustainable aviation fuel production by successfully integrating a highly efficient co-electrolysis process with fuel synthesis on an industrial scale. This achievement, part of the Kopernikus P2X project, aims to provide green alternatives for sectors like aviation, emphasizing the importance of sustainably produced kerosene. Utilizing water vapor/CO2 co-electrolysis technology from Sunfire, the process achieves up to 85% recovery of electrical energy for chemical energy in syngas production, enhancing overall efficiency. The co-electrolysis method simplifies the production of syngas, a crucial step in generating synthetic kerosene. By coupling co-electrolysis with Fischer-Tropsch synthesis, researchers can convert syngas to syncrude, a precursor for fuels like kerosene. The process, developed at KIT's Energy Lab, has undergone successful testing under real conditions, producing up to 100 liters of syncrude per day. Future plans involve scaling up production to 300 liters per day and eventually to a ton per day. INERATEC, a KIT spin-off, is commercializing the reactor technology used in the synthesis process. The project envisions the production of sustainable aviation fuel meeting strict industry standards, with plans for large-scale production in the near future. This advancement signifies a crucial step towards achieving sustainable aviation fuel production at a scale that can meet industry demands, showcasing the potential of innovative technologies for a greener future.
