Synthetic Fuel in Europe — Regulation, Policy & Roadmap

Definition

What is a synthetic fuel —
and what kinds exist?

The term "synthetic fuel" covers a family of liquid and gaseous fuels produced from non-fossil feedstocks. European regulation uses the term broadly — and each sub-category qualifies for different mandates and incentives.

Synthetic e-fuel (electrofuel)

Produced from renewable or low-carbon hydrogen + captured CO₂ via Power-to-Liquid synthesis (Fischer-Tropsch, methanol synthesis or Sabatier reaction). The "e" denotes electricity as the energy source. Chemically identical to fossil equivalents — drop-in compatible with all existing engines and infrastructure. Covered by ReFuelEU, FuelEU, RED III and the 2035 ICE exemption.

Synthetic fuel (broader category)

Any fuel produced from non-direct fossil extraction: includes Gas-to-Liquid (GTL), Coal-to-Liquid (CTL), biomass-to-liquid (BtL/BTL) and Power-to-Liquid (PtL). EU regulation specifically incentivises PtL (Power-to-Liquid) e-fuels and RFNBO-compliant fuels. GTL and CTL from fossil feedstock do not qualify for EU green mandates.

EU Regulatory Framework

Five regulations,
one direction of travel

The EU has built a coherent — if complex — regulatory architecture that creates binding demand for synthetic fuel across all hard-to-abate sectors. Each regulation targets a different sector with different mandates, timelines and qualifying fuel definitions.

ReFuelEU Aviation · Reg. 2023/2405

Sustainable Aviation Fuel Mandate

Binding SAF blending mandates for all flights departing EU airports. Fuel suppliers must blend increasing shares of SAF — including a specific Power-to-Liquid sub-mandate from 2030 (0.7%, rising to 35% by 2050). Synthetic e-kerosene is the primary long-term compliance pathway.

2025: 2% SAF · 2030: 6% (incl. 0.7% PtL) · 2035: 20% · 2050: 70% (incl. 35% PtL)

FuelEU Maritime · Reg. 2023/1805

Shipping GHG Intensity Reduction

Binding GHG intensity reduction targets for all ships over 5,000 GT calling at EEA ports. In force since January 2025. E-methanol and e-ammonia are the principal long-term compliance pathways. E-ammonia used in fuel cells receives a 2× compliance multiplier until 2033.

2025: −2% · 2030: −6% · 2035: −14.5% · 2040: −31% · 2050: −80%

RED III · Dir. 2023/2413

Renewable Energy Directive

Establishes binding RFNBO (Renewable Fuels of Non-Biological Origin) targets for industry: 1.2% of total energy use by 2030, 42% renewable hydrogen share in industry by 2030. Synthetic e-fuels produced from renewable H₂ qualify as RFNBO. Defines the technical criteria for "green" hydrogen and e-fuels.

Industry RFNBO: 1.2% by 2030 · Transport RFNBO: 5.5% by 2030

EU ETS · Dir. 2003/87/EC amended

Emissions Trading System

Carbon pricing mechanism covering aviation (since 2012), maritime (since 2024) and industry. ETS carbon prices (~€50–80/t CO₂) progressively narrow the cost gap between fossil fuel and synthetic fuel. Aviation: 50% free allowances phased out 2024–2026. Maritime: 100% coverage from 2026. Synthetic e-fuels receive full GHG credit under ETS methodology.

Aviation: full ETS from 2027 · Maritime: 40% coverage 2024 → 100% from 2026

EU 2035 ICE Exemption · Reg. 2023/851

E-Fuel-Only Road Vehicles After 2035

The EU's 2035 ban on new ICE vehicle sales includes a permanent exemption for vehicles running exclusively on synthetic e-fuels. Horse H12 (Renault/Geely, 2026) achieved 44.2% thermal efficiency on pure e-petrol — the world record. The exemption preserves the ICE market for e-fuel-compatible vehicles and their supply chains.

2035: new ICE banned · except: e-fuel-only certified vehicles permanently allowed

CBAM · Reg. 2023/956

Carbon Border Adjustment Mechanism

Carbon border tax on imports of carbon-intensive goods including hydrogen, ammonia, steel and fertilisers. In force from 2026. Creates a level playing field between EU producers using green hydrogen/e-fuels and non-EU competitors using fossil feedstocks. Supports the business case for European synthetic e-ammonia and e-hydrogen production.

Transitional: 2023–2025 · Full CBAM: from 1 January 2026

The mandates do not arrive all at once — they escalate progressively, giving producers and operators a planning horizon while creating certainty of demand at each milestone.

2035 TARGET

ICE exemption takes effect

New ICE vehicle sales banned except e-fuel-only · ReFuelEU: 20% SAF · FuelEU: −14.5% GHG · synthetic fuel becomes mainstream compliance tool across all sectors

2050 OBJECTIVE

Full decarbonisation targets

ReFuelEU: 70% SAF (incl. 35% PtL) · FuelEU: −80% GHG · EU climate neutrality · synthetic fuel the dominant decarbonisation pathway for aviation and shipping

Why the mandates matter for producers

EU regulation creates guaranteed demand pull — not dependent on carbon pricing alone. Airlines must blend SAF regardless of price. Shipping operators must reduce GHG intensity regardless of cost. This mandatory demand floor changes the investment calculus for synthetic fuel producers: revenue is partially de-risked by regulation before a tonne of fuel is sold.

The PtL sub-mandate in ReFuelEU is especially significant. From 2030, a minimum share of aviation SAF must specifically be Power-to-Liquid synthetic fuel — bio-SAF cannot substitute for it. This creates a protected market for e-kerosene that no amount of biofuel supply expansion can fill.

The 2035 ICE exemption signals that the EU accepts a permanent role for synthetic e-fuel in road transport — even after the electrification transition. Vehicles certified for e-fuel-only operation can be sold without restriction in perpetuity, creating a long-term market for synthetic e-petrol and e-diesel across Europe's existing vehicle fleet.

The key variable across all mandates is hydrogen feedstock cost. At €3–6/kg (green H₂ today), most synthetic fuels carry a significant green premium. At €0.50/kg (FDE Lorraine natural H₂ target, 2028), synthetic fuels approach or undercut fossil equivalents — and EU mandates shift from compliance cost to commercial advantage.

The feedstock that changes everything

Power-to-Liquid production economics: hydrogen feedstock = ~55% of total cost · natural H₂ at €0.50/kg vs green H₂ at €3–6/kg = 60–70% cost reduction across all synthetic fuels · Photo: Unsplash (free to use)

What natural hydrogen at €0.50/kg means for each EU mandate

ReFuelEU Aviation (e-kerosene) — falls from ~€2.50–3.50/L to ~€1.20/L · PtL sub-mandate becomes commercially self-sustaining without subsidy · airlines meet the 2030 PtL mandate at near-parity with fossil Jet-A1 with carbon pricing included
FuelEU Maritime (e-methanol) — falls from ~€920/t to ~€280/t · undercuts fossil methanol · FuelEU compliance becomes cost-neutral · shipping operators choose e-methanol on economics, not just regulation
FuelEU Maritime (e-ammonia) — falls from ~€800/t to ~€250/t · undercuts grey ammonia · with the 2× FuelEU multiplier until 2033, commercially dominant pathway for new vessels
2035 ICE exemption (e-petrol) — falls from ~€3.40/L to ~€1.60/L · near fossil parity · the ICE exemption becomes commercially viable at scale, not just a regulatory niche
RED III RFNBO (industrial e-fuels) — falls across the board · 1.2% industry mandate met at fraction of current compliance cost · accelerates voluntary adoption beyond the mandate floor

"At €0.50/kg hydrogen feedstock, every EU synthetic fuel mandate transforms from a compliance cost into a commercial advantage. The regulation creates the market; natural geological hydrogen makes it profitable."
