Gasification & Fischer-Tropsch sustainable aviation fuel
Municipal solid waste, forestry residue and captured biogas are gasified into syngas and built up into jet-range hydrocarbons via Fischer-Tropsch synthesis — a thermochemical pathway distinct from the HEFA and alcohol-to-jet routes that dominate today's certified SAF supply, with 2026 commercial-stage projects in the UK, South Africa-licensed technology and a first US biogas-to-jet pilot.
1 · What it gives
Gasification-and-Fischer-Tropsch (FT) sustainable aviation fuel is a thermochemical route that converts solid or gaseous waste and biomass into jet-range hydrocarbons through two steps: gasification breaks the feedstock down into synthesis gas (syngas, a mixture of CO and H2) at high temperature, and Fischer-Tropsch synthesis then builds that syngas back up into long-chain hydrocarbons over a catalyst, which are hydroprocessed into a certified aviation-fuel blendstock. This is chemically distinct from the two pathways that dominate today’s certified SAF supply — HEFA (hydrotreating waste fats and oils) and alcohol-to-jet (dehydrating and oligomerizing bioethanol) — because it can accept feedstocks neither of those pathways can use: non-recyclable municipal solid waste, forestry residue, and raw biogas straight from an anaerobic digester. A single 2026 commercial pilot converted raw dairy-farm biogas to jet fuel end-to-end over a six-month run at a projected capital cost roughly one-fifth of a conventional European SAF plant, and a UK Fischer-Tropsch system using modular microchannel reactors was commissioned the same year, signalling the pathway moving from demonstration toward first commercial units.
The key directions of gasification & Fischer-Tropsch SAF are:
- Municipal solid waste to SAF (Waste-to-SAF): non-recyclable household and commercial waste is gasified to syngas and built up into synthetic hydrocarbons, giving a feedstock route that competes with landfilling rather than with food or fuel crops.
- Biogas and renewable natural gas to SAF (Biogas-to-SAF): raw biogas or RNG from manure digesters, landfills or wastewater plants — feedstock too impure for direct pipeline injection in many cases — is reformed to syngas and converted via Fischer-Tropsch, turning an existing waste-management byproduct into aviation fuel.
- Forestry and wood-waste residue gasification (Wood-Waste-to-SAF): abundantly available wood residue is gasified for large-scale FT synthesis, the feedstock base behind 2026’s largest publicly announced project pipeline.
- Modular microchannel Fischer-Tropsch reactors (Microchannel FT Engineering): compact, factory-built reactor trains that bring FT synthesis — historically only economic at giant gas-to-liquids scale — down to a size that matches a single waste or biogas site’s feedstock volume.

Cross-cutting technologies of the sector:
- Microchannel Fischer-Tropsch reactors (Microchannel FT Engineering): compact reactor cores that intensify the FT reaction’s heat management, letting plants be built at a scale matched to a single waste or biogas site rather than requiring giant gas-to-liquids trains.
- Electrified syngas conditioning (Electrified Reverse Water-Gas Shift): electric heating of the reverse water-gas-shift step that adjusts syngas composition ahead of FT synthesis, cutting the process’s reliance on burning part of the feedstock for heat.
- Modular, low-capex plant design (Modular Waste-to-Fuel Plant Design): factory-built, single-train plant architectures sized to a waste site’s feedstock volume, targeted at capital costs well below traditional large-scale FT gas-to-liquids plants.

United States
The United States hosts the first confirmed end-to-end commercial pilot converting raw biogas straight from a manure digester into jet fuel, positioning the country as an early mover on the biogas-to-SAF slice of the pathway.
dairy-biogas-to-jet pilots, low-capex modular design, farm-level feedstock economics#
- Circularity Fuels: completed what it describes as the world’s first end-to-end conversion of raw agricultural biogas into SAF over a six-month pilot run on methane-rich biogas drawn directly from a California dairy farm’s manure digester, targeting projected commercial capital costs roughly one-fifth of a conventional European SAF plant and offering dairy farms a new revenue stream alongside airlines a lower-cost path to mandated SAF volumes.
European Union
Europe (loosely defined here to include South African technology licensed into European and international projects) hosts the pathway’s most mature Fischer-Tropsch technology providers, both licensing into 2026 commercial-scale project pipelines.
commissioned FT systems, wood-waste feedstock licensing, microchannel reactor roadmaps#
- Velocys: a Fischer-Tropsch technology provider that commissioned a Fischer-Tropsch system with partner SuMo at its Wednesbury facility in the UK in March 2026, advancing a waste-to-SAF pathway; its NovaSAF 1 project is described as the first all-electric biogas-to-SAF development built on the same chemistry, and in July 2026 the company announced a product roadmap led by its AlphaCore reactor line aimed at extending microchannel FT performance into larger, more cost-competitive commercial SAF plants.
- Sasol: the South African Fischer-Tropsch technology group, founded in 1950 on the country’s coal-and-gas-to-liquids heritage, signed 2026 licensing and engineering agreements with SUSTAERO for a wood-waste-fed SAF project in Canada (planned initial capacity 3,200 barrels/day, final investment decision expected 2028) and with Allied Biofuels for a project in Uzbekistan, both delivered jointly with Topsoe under the jointly marketed G2L process.
- Topsoe: the Danish catalysis and process-technology group supplies the electrified reverse water-gas-shift step (eREACT) that pairs with Sasol’s Fischer-Tropsch synthesis in G2L; beyond the SUSTAERO and Allied Biofuels licensing deals, Topsoe’s G2L technology was also selected in May 2026 to power a large e-fuels demonstration plant at Leuna, Germany, and its own FrontFuel concept targets converting biogas and biogenic CO2 to SAF directly.
China
China’s public activity on this specific pathway is visible mainly as patent filings and market-outlook coverage rather than a named commercial gasification-FT-SAF producer.
patent-stage filings, market-outlook coverage, no confirmed commercial anchor#
- Patent and explainer activity: Chinese-language searches surfaced a patent application for a sustainable-aviation-fuel production system and a solar-driven biomass-gasification SAF method, alongside general-audience explainers on what “bio-aviation fuel” is and market-outlook reports projecting 2026–2032 growth for the category — none of which named a specific commercial gasification-FT-SAF operator confirmed to be running a project in 2026.

7 · Tech stack & innovations
The stack is built to make Fischer-Tropsch synthesis — a chemistry long proven only at giant national gas-to-liquids scale — economic at the scale of a single waste or biogas site.
- Microchannel reactor engineering (Microchannel FT Reactor Design):
- Velocys’s AlphaCore product line intensifies the FT reaction’s heat management inside compact, factory-buildable reactor cores, the first stage of a roadmap explicitly aimed at extending the same chemistry into larger, more cost-competitive plants.
- The same core technology underpins both the company’s waste-to-SAF (Altalto) and biogas-to-SAF (NovaSAF 1) project lines, differing mainly in feedstock front-end.
- Electrified syngas conditioning (Electrified Reverse Water-Gas Shift):
- Topsoe’s eREACT electrified reverse water-gas-shift step, paired with Sasol’s Fischer-Tropsch synthesis under the jointly marketed G2L process, adjusts syngas composition using electric heat rather than combusting part of the feedstock.
- This pairing is the basis of both the SUSTAERO (Canada) and Allied Biofuels (Uzbekistan) 2026 licensing deals, applied to wood-waste and other biogenic feedstocks respectively.
- Low-capex modular plant design (Modular Waste-to-Fuel Plant Architecture):
- Circularity Fuels’ pilot targets commercial capital costs at roughly one-fifth of a conventional European SAF plant by sizing the plant to a single farm’s biogas volume rather than building a centralized mega-facility.
- This modular economics argument is what lets the pathway plausibly reach distributed, farm- or waste-site-level feedstock sources that a giant centralized gas-to-liquids plant could never be sited against.
