| Our breakthrough sustainable aviation fuel (SAF) technology, aerobrew™, will make affordable net-zero aviation a reality. The technology is innovative, highly scaleable and able to tap into future global renewable energy systems efficiently. Starting from renewable feedstocks including green hydrogen, driven by renewable electricity, andsustainably sourced CO2, for example from direct air capture, aerobrew™ provides an efficient route to large-scale production of e-kerosene, overcoming the scale up challenges and high costs of alternative e-fuels technologies. aerobrew™ is also compatible with the biogenic route whereby the carbon required for the process is derived from renewable and sustainable cellulosic biomass which, does not compete with the food chain (wood, miscanthus, etc.). With a high carbon conversion, high selectivity and a high overall SAF yield, aerobrew™ leads to attractive production economics and cost leadership.
