GREEN Hydrogen H2
Green hydrogen is produced through the electrolysis of water. Electricity from renewable energy sources is used for this. Green hydrogen is therefore CO2-free.
GREEN Methanol CH₃OH
Green methanol can be produced either from biogenic raw materials (e.g. biomass gasification) or carbon dioxide (CO2) extracted from the air together with green hydrogen (from water electrolysis with sustainable electrical energy).
GREEN Kerosene
With a few further process steps, this green methanol can finally be processed into synthetic kerosene and thus a CO2-neutral alternative to traditional aircraft fuel. “Although CO2 is also produced when synthetic kerosene is burned, the crucial difference is that only as much CO2 is released into the atmosphere as was previously removed for the production of green methanol, for example through artificial CO2 capture,” says Prank. The combustion of sustainable aviation fuels is therefore CO2-neutral in its balance sheet.
GREEN Ammonia NH3
Green ammonia is produced artificially through the synthesis of CO2-neutral hydrogen and nitrogen in the so-called Haber-Bosch process. The ammonia molecule consists of the combination of one nitrogen with three hydrogen atoms and is free of carbon.
