Synthetic fuel:
how it's made —
the technology, the reactors,
the European plants

Synthetic fuel is produced by combining renewable or low-carbon hydrogen with CO₂ through chemical synthesis. The technology is proven — Fischer-Tropsch, methanol synthesis and Haber-Bosch have operated at industrial scale for decades. What is new is the feedstock: green or natural hydrogen replacing fossil gas. This portal covers the production process, the key technologies and the European plants bringing it to commercial scale.

The production process

From energy source to liquid fuel —
the Power-to-Liquid chain in 5 steps

Every synthetic fuel follows the same five-step production chain. The energy source, hydrogen production method and synthesis pathway can vary — but the logic is always the same: combine hydrogen with carbon to form a liquid hydrocarbon. Here is how it works.

Why the technology is proven

Fischer-Tropsch synthesis was invented in 1923 by Franz Fischer and Hans Tropsch at the Kaiser Wilhelm Institute in Berlin. By 1944, Nazi Germany was producing 124,000 tonnes per month of synthetic fuel from coal using 25 Fischer-Tropsch plants — supplying 92% of the Luftwaffe's jet fuel and 46% of its diesel.

South Africa's Sasol has operated continuous Coal-to-Liquid Fischer-Tropsch production since 1955 — over 70 years without interruption. The chemistry is not experimental. What is new in Power-to-Liquid is the feedstock: renewable hydrogen and captured CO₂ replacing coal and fossil gas as the carbon and hydrogen source.

The result is the same molecular structure — chemically identical to fossil fuel — with a lifecycle GHG footprint reduced by 85–95%.

The three bottlenecks — and their solutions

Electrolyser cost and efficiency — today's PEM electrolysers cost €600–900/kW and operate at ~70–80% efficiency (LHV). By 2030, IEA projects costs below €300/kW and efficiency above 85%. SOEC (solid oxide electrolysis cells) operating at high temperature can reach 90%+ but require stable heat input.

CO₂ capture cost — direct air capture (DAC) today costs $300–600/t CO₂. Point-source capture (from industrial exhausts) costs $50–100/t. DAC cost needs to fall to ~$100/t for PtL to reach fossil parity at €1.50/kg H₂. Alternatively, natural geological H₂ eliminates the need for electrolysis and reduces the pressure on DAC cost.

Scale — ERA ONE at 2,500 t/yr is a proof of concept. Commercial-scale PtL plants targeting 100,000+ t/yr are needed to meet ReFuelEU mandates. Capital cost at scale is the primary challenge — and the primary opportunity for early movers in the European market.

Synthesis technologies

Three synthesis pathways —
three different output fuels

The synthesis step — where hydrogen and carbon combine to form the output fuel — determines the product. Three pathways cover all commercially relevant synthetic fuel outputs. Each has different energy requirements, efficiency profiles and target markets.

Pathway 1 · Aviation · Road · Marine

Fischer-Tropsch Synthesis

CO + 2H₂ → (CH₂)n + H₂O

Converts synthesis gas (CO + H₂) into long-chain hydrocarbons via a cobalt or iron catalyst at 150–350°C. Produces a wide range of liquid fuels — e-kerosene (SAF), e-diesel and e-petrol — depending on the hydrocracking and fractionation profile. Chemically identical to petroleum refinery outputs. ASTM-certified for aviation up to 50% blend. Pioneer: INERATEC ERA ONE, Frankfurt.

Efficiency: 44–55% overall · Key players: INERATEC, Sunfire, HIF, Norsk e-Fuel

Pathway 2 · Maritime · Chemical industry

Methanol Synthesis

CO₂ + 3H₂ → CH₃OH + H₂O

Direct CO₂ hydrogenation over a copper-zinc oxide catalyst at 200–300°C and 50–100 bar. Produces e-methanol — liquid at ambient temperature, easily stored and transported. The dominant synthetic marine fuel pathway. Maersk's dual-fuel methanol fleet (100+ vessels) is supplied by European Energy's Kassø plant (42,000 t/yr, Denmark). Can be further processed to e-petrol via MTG (methanol-to-gasoline).

Efficiency: 55–62% overall · Key players: European Energy, Carbon Recycling International, Methanex

Pathway 3 · Maritime · Agriculture · Power

Haber-Bosch (E-Ammonia)

N₂ + 3H₂ → 2NH₃

Atmospheric nitrogen + hydrogen over an iron catalyst at 400–500°C and 150–300 bar. Produces e-ammonia — the only synthetic fuel that requires no CO₂ capture (atmospheric N₂ is the carbon-free feedstock). Zero carbon combustion. Yara Eyde entered commercial container shipping service on Oslo–Hamburg in 2026. FuelEU Maritime awards 2× compliance multiplier for e-ammonia fuel cells until 2033.

Efficiency: 55–65% overall · Key players: Yara, NEOM, Air Products, CF Industries

The electrolyser — the technology that makes PtL possible

PEM (Proton Exchange Membrane) — most common in new PtL installations · high efficiency (70–80% LHV) · fast response to variable renewable power · cost €600–900/kW today · target <€300/kW by 2030 · ITM Power, Nel, Siemens Energy, Plug Power
AEL (Alkaline Electrolysis) — the oldest technology · lower cost today (€400–700/kW) · lower efficiency (65–75%) · established at large scale · less responsive to variable power · thyssenkrupp nucera, Nel, John Cockerill, McPhy
SOEC (Solid Oxide Electrolysis Cells) — highest efficiency (90%+ with heat recovery) · operates at 700–900°C · ideal for industrial sites with waste heat · not yet at large commercial scale · Sunfire, Bloom Energy, Elcogen
Natural H₂ bypass — FDE's geological H₂ at €0.50/kg (target 2028) eliminates the electrolyser step entirely · the hydrogen is extracted rather than manufactured · eliminates ~40% of total PtL CAPEX and reduces OPEX by ~55%

Production costs

What synthetic fuel costs
to produce — today, in 2030, with natural H₂

Production cost is the central question for the synthetic fuel industry. Hydrogen feedstock represents ~55% of total cost — which is why the Lorraine natural hydrogen project (FDE target: €0.50/kg by 2028) has attracted such attention from energy analysts and industrial buyers.

Output fuel	H₂ €3–6/kg (today)	H₂ €1.5/kg (2030 target)	H₂ €0.50/kg (FDE 2028 target)	Fossil equivalent
E-kerosene (SAF)	~€2.50–3.50/L	~€1.50–1.80/L	~€1.20/L	~€0.70–0.90/L
E-petrol	~€3.20–3.80/L	~€1.80–2.00/L	~€1.50–1.60/L	~€0.70–0.90/L
E-diesel	~€1.50–2.00/L	~€0.90–1.10/L	~€0.75–0.85/L	~€0.60–0.80/L
E-methanol	~€800–1,000/t	~€400–500/t	~€260–300/t	~€350–450/t
E-ammonia	~€700–900/t	~€360–420/t	~€230–270/t	~€300–420/t

"The technology has been proven for a hundred years. The chemistry has not changed since Fischer and Tropsch. What has changed is the feedstock — and what could change it again is the geology of Lorraine."
