# 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.

## Overview and value chain
Markers: [EC: ASTM D7566 Annex A1 (FT-SPK) certification | OECD: Bioenergy | Regulator: EPA (USA), ADEME (France)]
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:
1. **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.
2. **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.
3. **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.
4. **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.

## US
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.

## CN
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.

## EU
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.

## Tech stack and 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.
1. **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.
2. **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.
3. **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.

```
#### Stage 1: Feedstock collection
Non-recyclable municipal solid waste, forestry and wood-processing residue, or raw biogas
from a manure digester, landfill or wastewater plant is gathered and prepared to a
consistent feed specification for the gasifier or reformer.
#### Stage 2: Gasification
The prepared feedstock is converted at high temperature under limited oxygen into raw
synthesis gas, a mixture of carbon monoxide and hydrogen, breaking down the original
solid or gaseous waste structure entirely rather than merely refining it.
#### Stage 3: Syngas cleanup
Tars, particulates and sulfur compounds are removed from the raw syngas and its
hydrogen-to-carbon-monoxide ratio is adjusted — increasingly via an electrified
reverse water-gas-shift step — to the composition the Fischer-Tropsch catalyst requires.
#### Stage 4: Fischer-Tropsch synthesis
Conditioned syngas passes over a Fischer-Tropsch catalyst, which polymerizes the CO and
H2 into long-chain hydrocarbons; modular microchannel reactor designs let this step run
economically at a scale matched to a single feedstock site rather than requiring a
giant centralized gas-to-liquids train.
#### Stage 5: Hydroprocessing
The Fischer-Tropsch syncrude is hydrocracked and isomerized into fuel-range cuts,
separating a jet-range synthetic paraffinic kerosene fraction from naphtha and diesel
co-products.
#### Stage 6: Blending and certification
The synthetic paraffinic kerosene is blended with conventional Jet-A fuel up to the
certified limit under ASTM D7566 Annex A1 and delivered as an airport-ready blended
aviation fuel, closing the pipeline that began with a waste or biogas feedstock.
