Synthetic Fuel / E-Fuel
Liquid fuel synthesised from green hydrogen and captured CO₂ — a drop-in decarbonisation option for aviation and shipping.
Definition
Synthetic fuels (e-fuels) are liquid or gaseous hydrocarbon fuels produced by combining green hydrogen (from renewable-powered electrolysis) with captured carbon dioxide — via Fischer-Tropsch synthesis or methanol routes — yielding e-kerosene, e-methanol, e-diesel or synthetic methane chemically identical to fossil fuels. Because they are drop-in compatible with existing engines and infrastructure, they are a leading decarbonisation option for aviation and shipping, where direct electrification is impractical.
