The Problem (and Promise) of Synthetic Fuel: Future of Transport or Green Policy Disaster?

Synthetic fuels are presented as a large, strategic market—with global liquid‑fuel use exceeding 4 trillion liters annually—and an especially important decarbonization pathway for hard‑to‑abate sectors like shipping, heavy industry, and aviation. The industry has converged on green hydrogen, advanced biofuels, and power‑to‑liquid e‑fuels, with e‑fuels offering drop‑in compatibility and faster industrial uptake while hydrogen and biofuels face efficiency and feedstock limits. Strong policy signals and rising investment (from about $25bn in 2025 toward ~$100bn by 2030), along with options like geothermal heat to lower costs, improve the economics, but high prices, pollutant concerns, and scaling challenges keep broad commercial deployment uncertain.

Key Takeaways

Global liquid‑fuel demand (over 4 trillion liters/year) plus recent geopolitical shocks (Russia–Ukraine, Middle East) create a large addressable market and strategic impetus for synthetic drop‑in fuels, but the episode stresses that fossil hydrocarbons will remain part of the energy mix for the foreseeable future.

The technology base for today's sustainable fuels dates to 1990s commercialization and has converged into three main pathways—green hydrogen, advanced biofuels, and power‑to‑liquid e‑fuels—with e‑fuels highlighted as an especially promising route for near carbon‑neutral, large‑scale synthesis.

E‑fuels gain a practical advantage over green hydrogen and many biofuels because hydrogen faces large end‑to‑end energy losses (roughly 50–80%) and biofeedstocks are limited, whereas e‑fuels are drop‑in, run in existing engines, and can be produced ultra‑cleanly from captured CO2 plus clean hydrogen.

Maritime shipping and heavy industry are already early adopters—using e‑methanol, e‑methane, e‑ammonia and synthetic fuels often paired with carbon capture—to meet IMO targets and decarbonize high‑temperature processes, with policy mandates and funding accelerating these deployments.

APPLICATIONS

Industrial Demand — Shipping is already using e‑methanol, e‑methane and e‑ammonia to help meet IMO greenhouse‑gas targets, and heavy industry is deploying synthetic fuels—often paired with carbon capture—to decarbonize high‑temperature processes like steel, cement, and chemicals. Policy mandates and funding (e.g., EU renewable directives and U.S. hydrogen‑hub grants) are supporting these industrial deployments.

“The maritime industry is also making use of synthetic fuel, specifically e-methanol, e-methane, and e ammonia to fuel containers ships, tankers, and cargo vessels…”—

AVIATION

Aviation Challenge — Long‑haul aviation requires energy‑dense, drop‑in fuels, making synthetic jet fuels a key decarbonization pathway. Yet synthetic aviation fuels are under 1% of liquid fuels, carry pollutant/externality concerns, and cost roughly 7–10× more than fossil jet fuel, so mandates and policy support are critical to scale adoption.

“We don't really understand any other mechanism to be able to fly longhaul flights or at the pace that jet aviation takes without the use of very energy dense fuels.”—

COST-AND-TECHNOLOGY

Investment Surge — Synthetic‑fuel capital expenditure reached roughly $25 billion in 2025, and the documentary cites projections that investment could quadruple to about $100 billion by 2030 to meet national and corporate decarbonization pledges, implying a near‑term surge in project development.

“Annual capital expenditure in synthetic fuels reached approximately $25 billion in 2025 and is projected to quadruple to 100 billion by 2030 to meet national and corporate pledges for decarbonization.”—

GEOTHERMAL

Geothermal Advantage — High‑temperature geothermal steam—available continuously with roughly a 90% capacity factor—can increase hydrogen production efficiency when paired with solid‑oxide electrolysis and lower costs. Since renewable electricity is about 70% of e‑fuel production costs today, reliable geothermal heat reduces sensitivity to intermittent wind/solar and materially improves levelized hydrogen and e‑fuel economics.

“Because renewable energy is a vital input to the manufacturing process, the majority of the current inflated price tag on producing e-fuels is dominated by renewable energy generation costs with…”—

LIQUID-FUELS

Addressable Market — Global liquid‑fuel consumption exceeds 4 trillion liters per year and is expected to grow, creating a substantial market for drop‑in synthetic fuels. Geopolitical shocks (Russia–Ukraine, the war in the Middle East) have increased emphasis on energy sovereignty and diversified supply chains, even as fossil hydrocarbons are likely to remain part of the mix for the foreseeable future.

“These substances make up the majority of the over 4 trillion L per year of liquid fuels consumed worldwide, and that number is only projected to grow.”—

POLICY-INCENTIVES

Policy Signals — The EU's ReFuelEU Aviation creates a progressive blending mandate (2% in 2025, rising toward 70% by 2050) backed by subsidies to provide a multidecade demand signal. U.S. measures under the Inflation Reduction Act—tax credits, loan guarantees, and the Clean Fuel Production Credit—reduce capital risk and improve e‑fuel project economics.

“In the European Union, the refuel EU aviation initiative requires progressive blending of synthetic kerosene for all commercial airlines operating in EU airports…”—

SCALABILITY-ADOPTION

Scalability Limits — Green hydrogen suffers large end‑to‑end energy losses (roughly 50–80%) and many biofuels lack sufficient feedstock to scale, limiting their ability to substitute fossil fuels at scale. E‑fuels, by contrast, are drop‑in, run in existing engines, can be synthesized ultra‑cleanly by capturing impurities during production, and are already seeing accelerating industrial deployment.

“Because the other options are either inefficient, as is the case with green hydrogen, with 50 to 80% of the original renewable energy used to create it lost across the…”—

SYNTHETIC

Production Routes — Synthetic fuels are produced from syngas (carbon monoxide + hydrogen) derived from coal, natural gas, biomass or—from the lowest‑carbon route—captured CO2 combined with renewable (green) hydrogen. Modern sustainable fuel strategies therefore include green hydrogen, advanced biofuels, and power‑to‑liquid e‑fuels that synthesize hydrocarbons from captured carbon and clean hydrogen.

“Synthetic fuel is typically a liquid or gaseous hydrocarbon made from sin gas, a mix of carbon monoxide and hydrogen derived from feed stocks like coal, natural gas, biomass, or…”—

TECHNOLOGY-EVOLUTION

E‑Fuel Pathway — Commercial synthetic and renewable‑diesel technologies became viable in the 1990s, laying the technical foundation for today’s sustainable fuels. Since the 2010s the field has coalesced around green hydrogen, advanced biofuels, and power‑to‑liquid e‑fuels, with e‑fuels highlighted as especially promising for larger‑scale, near carbon‑neutral adoption when paired with renewables.

“Gastoli liquids technologies became commercially viable in the 1990s by transforming natural gas into cleaner burning synthetic liquids…”—
