The fuels that already exist.
Made from hydrogen and air.
E-fuels are synthetic liquid fuels chemically identical to petrol, diesel and kerosene — but produced from green hydrogen and captured CO₂. They run in every existing engine. No modifications. No new infrastructure.

E-fuels — also called electrofuels, Power-to-Liquid fuels or synthetic fuels — are produced by combining green or natural hydrogen with CO₂ captured from the atmosphere or industrial sources. The result is a hydrocarbon liquid chemically identical to fossil fuels.
The core process — Fischer-Tropsch synthesis — was invented in Germany in 1925 and is well understood at industrial scale. What is new is the feedstock: renewable hydrogen instead of fossil-derived syngas.
E-fuels work in every existing internal combustion engine, aircraft and ship without any modification. They use existing fuel distribution infrastructure. They are the only realistic pathway to decarbonise aviation and maritime transport at scale.
€0.50/kg, everything changes
The main barrier to e-fuels has always been the cost of hydrogen. At €6.20/kg for electrolytic green hydrogen, e-petrol costs approximately €3.40/L — twice the fossil price.
Natural geological hydrogen from Lorraine (France) — currently under exploration by REGALOR II, with commercial results expected in 2027 — targets a production cost of €0.50/kg. At that price, e-petrol approaches pump parity. E-kerosene becomes viable without subsidy.
Belgium's BE.Hydrogen programme, launched May 2026, is exploring adjacent geological formations in Wallonia. The HY4Link pipeline (EU PCI status) will connect these sources across the Greater Region.
