Metafuels' 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, and sustainably sourced CO2, for example from direct air capture, aerobrew" provides an efficient route to large-scale production of e-kerosene. With a high carbon conversion, high selectivity and a high overall SAF yield, aerobrew" leads to attractive production economics and cost leadership. With a rapidly growing demand for SAF, aerobrew" stands to contribute significantly to the decarbonisation of global aviation.
