E-fuels are at the centre of Europe’s most debated energy policy. The EU 2035 ICE ban, the ReFuelEU Aviation mandates, FuelEU Maritime and the US Inflation Reduction Act are reshaping the entire transport and energy landscape. This guide explains what e-fuels are, why EU regulation makes them indispensable, and what the 2035 deadline really means for drivers, airlines, shipowners and industry.
What Are E-Fuels? The Simple Explanation
E-fuels (electrofuels) are synthetic fuels produced from renewable electricity + green hydrogen + captured CO₂. The process — called Power-to-Liquid (PtL) — creates liquid hydrocarbons chemically identical to conventional petrol, diesel or jet fuel.
The critical difference: the carbon used comes from CO₂ already in the atmosphere, not from underground fossil deposits. When the e-fuel is burned, it releases only the CO₂ that was previously captured — making it carbon-neutral in a closed loop, when powered by renewable electricity.
The EU 2035 ICE Ban — And the E-Fuel Exemption
In July 2021, the European Commission proposed banning the sale of new petrol and diesel cars from 2035 as part of the Fit for 55 package. After intense lobbying — led notably by Germany, Porsche and the eFuel Alliance — a critical compromise was reached in March 2023.
New internal combustion engine (ICE) vehicles can continue to be sold after 2035 — but only if they run exclusively on certified synthetic e-fuels. The European Commission committed to creating a specific vehicle sub-category for “e-fuel only” cars under the type-approval regulation.
You will be able to buy a new ICE car after 2035 — if it is certified to run only on e-fuels. Existing ICE cars are not affected at all by the 2035 regulation.
Porsche, BMW, Mercedes and others can continue making ICE engines post-2035 — if those engines are e-fuel certified. Major investment in e-fuel compatibility ongoing.
The methodology to certify “e-fuel only” vehicles under type-approval is still being finalised by the European Commission. Practical implementation is complex.

ReFuelEU Aviation — The SAF Mandate Explained
ReFuelEU Aviation (EU Regulation 2023/2405) entered into force on 1 January 2024. It applies to all flights departing from EU airports — regardless of the airline’s nationality. Fuel suppliers must blend increasing proportions of Sustainable Aviation Fuel (SAF) into conventional jet fuel.
ReFuelEU contains a specific sub-mandate for Power-to-Liquid synthetic fuels — not just any SAF. This is critical: HEFA (from waste oils) counts as SAF but not as synthetic. The sub-mandate ensures a guaranteed market for PtL/e-fuels regardless of HEFA availability. By 2050, 35% of all EU aviation fuel must be synthetic — equivalent to tens of millions of tonnes annually.
Which Sectors Need E-Fuels Most?
Cannot be electrified. ReFuelEU mandates. SAF market $25.6B by 2030. IATA: 65% of decarbonisation via SAF by 2050.
Deep-sea shipping impossible to electrify. FuelEU Maritime: -2% GHG 2025 → -80% 2050. E-methanol, e-ammonia lead.
200M+ ICE vehicles in EU in 2035. E-fuel exemption from ICE ban. Porsche, BMW, Mercedes investing heavily.
Steel, chemicals, high-temperature processes. E-hydrogen, e-methanol replace fossil feedstocks. ArcelorMittal, Thyssenkrupp.
