South African energy and chemicals group Sasol and Danish decarbonisation technology company Topsoe have formed a 50:50 JV to develop, build, own, and operate drop-in sustainable aviation fuel (SAF) plants globally. The fuels will be produced primarily from non-fossil feedstock – such as green hydrogen, biomass and sustainable sources of carbon dioxide – using Sasol’s Fischer Tropsch and Topsoe technologies, such as its Hydroflex solution to process vegetable oils, waste oils, or fats into HEFA-based SAF.
