The Enforcement Gap and What It Signals for 2030–2032

ReFuelEU Aviation mandates progressive SAF blend targets — 2 % by 2025, rising steeply through the decade — backed by financial penalties on non-compliant aircraft operators and fuel suppliers. When 13 Member States missed the December 2024 deadline to notify their penalty frameworks, they created an enforcement vacuum. The Commission’s June 2026 infringement action is the predictable response, but its broader message is this: Brussels will pursue implementation gaps, not paper over them. Compliance directors planning e-fuel supply chains to 2030 and 2032 should treat this episode as a rehearsal for how RED III and the 2035 ICE carve-out will be policed.

For road-transport synthetic fuels the stakes are equally concrete. The 2035 ICE exemption — which allows new internal-combustion cars to be sold after 2035 provided they run exclusively on carbon-neutral e-fuels — is contingent on the Commission establishing a robust certification and penalty regime. The infringement proceedings against ReFuelEU laggards demonstrate that the Commission has both the appetite and the legal tools to act when Member States drag their feet.

Geopolitical Price Shocks Expose the Cost Argument for E-Fuels

The Strait of Hormuz closure in Q2 2026 drove European SAF prices to $2,830 per tonne — 31 % above the 2026 average and roughly double the price of conventional jet fuel, according to BloombergNEF. Critics of synthetic fuels routinely cite their cost premium as a fatal flaw, and in the short term those critics have data on their side: e-fuels remain expensive. The honest counter-argument is not that e-fuels are cheap today, but that their feedstock — renewable electricity and captured CO₂ — is geopolitically insulated in ways that crude oil is not. A Hormuz shock pushes fossil-jet prices up; it does not affect the wind-power tariff underpinning a Power-to-Liquid plant in Denmark or Patagonia.

It is equally important to be candid about the road-transport efficiency question. Well-to-wheel, an e-fuel internal-combustion powertrain converts roughly 13–20 % of the original renewable electricity into motion, versus 70–80 % for a battery-electric vehicle — approximately five times more electricity for the same kilometre. That gap is the central argument of Transport & Environment and the ICCT, and it is a legitimate one for light passenger cars where BEVs are viable. E-fuels earn their strongest case in sectors where batteries cannot reach: long-haul aviation, deep-sea shipping, heavy trucking, and the 1.4 billion combustion vehicles already on the road that will not be scrapped overnight. Projects such as HIF Global’s Haru Oni facility and Horse Powertrain’s H12 engine — claiming 44.2 % thermal efficiency and 3.3 L/100 km WLTP on 100 % renewable fuel — point toward a future where efficiency losses are partially recovered at the engine level, but the electricity-intensity disadvantage does not disappear.

Compliance Calendar: Actions for Directors Mapping 2030–2032

Three immediate priorities emerge from the infringement proceedings. First, map Member State exposure: if your supply chain routes SAF or e-fuel through any of the 13 non-compliant states, your off-take agreements may rest on penalty frameworks that do not yet legally exist — a contractual risk. Second, stress-test RED III additionality and carbon-accounting assumptions against the possibility that the Commission tightens enforcement timelines as it has done here. Third, engage early with national competent authorities on the 2035 ICE certification pathway; the infringement episode shows that late engagement is punished, not accommodated.

Pump-price parity for e-petrol — the horizon that makes the 2035 ICE exemption commercially meaningful — depends on scaling electrolyser capacity, securing low-cost renewable power purchase agreements, and locking in long-term CO₂ supply. Natural geological hydrogen, where it is confirmed and commercially extractable, could reduce the electricity cost embedded in e-fuel production and partially close the efficiency gap critics highlight. But no such resource has been confirmed in Belgium or most of western Europe yet; the Belgian BE.Hydrogen programme launched in March 2026 is a geological survey, not a discovery. Directors should plan around electrolytic green hydrogen as the primary feedstock through 2032.
