While most of the climate spotlight falls on electric cars and giant wind farms, a new generation of synthetic fuels is silently moving from lab benches to industrial scale — and a French technology built around e‑methanol now claims a serious head start.
From niche start-up to strategic player
The company at the centre of this shift is KHIMOD, a young French firm based in Wissous, in the Paris region. It has just secured three patents covering a new way to produce e‑methanol and has validated the process on an industrial pilot unit, nicknamed THOR.
E‑methanol is synthetic methanol made from captured CO₂ and low‑carbon hydrogen, without tapping fossil resources. It can be burned directly as a marine fuel, used as a building block for sustainable aviation fuels, or serve as a feedstock for the chemical industry. That combination makes it one of the workhorse molecules for industrial decarbonisation.
E‑methanol turns waste CO₂ and green hydrogen into a versatile liquid that fits existing tanks, ships and pipelines.
While e‑fuels have long been viewed as promising but expensive, KHIMOD’s patents focus on the core bottleneck: how to make more e‑methanol with less equipment, less catalyst and more stable reactors.
Turning the pressure up to 300 bar
Most commercial e‑methanol technologies work at pressures of around 50–80 bar. KHIMOD chose a radically different path: push the process to nearly 300 bar.
At these higher pressures, the chemical equilibrium shifts in favour of methanol formation. More of the incoming CO₂ is converted rather than slipping through unreacted. This translates into higher yields and the potential for smaller production units.
The flip side is brutal: the reaction becomes highly exothermic. In plain language, it throws off huge amounts of heat. In a conventional reactor, that heat creates hot spots, destabilises the catalyst and can make the process almost impossible to control at scale.
The milli-structured reactor that keeps its cool
KHIMOD’s answer lies in its speciality: milli‑structured reactor‑heat exchangers. Instead of a large, relatively uniform vessel, the process runs through a dense network of tiny channels, giving the equipment an enormous surface area for heat transfer.

This geometry allows heat to be evacuated almost instantly. The reaction stays within a narrow, well-controlled temperature window, even at very high pressure.
By tightly steering temperature, the company claims it “pilots” the chemistry rather than enduring it.
In practice, this means the reactor behaves more like a precision industrial tool than a temperamental chemical beast. The patents protect both the design of these milli‑structured reactors and the way they are integrated with the high‑pressure methanol synthesis process.
Numbers that make heavy industry listen
On its THOR pilot in Wissous, KHIMOD has recorded performance figures that stand out sharply from current benchmarks.
- CO₂ conversion rates up to three times higher than reference technologies.
- Catalyst productivity up to 25 kg of e‑methanol per kg of catalyst, versus roughly 1 kg in traditional setups.
- Plant footprint divided by about four for an equivalent output.
Higher conversion means less recycling of unreacted gases and smaller compressors. High catalyst productivity cuts both material costs and replacement frequency. A more compact unit translates into lower capex and easier siting near ports, industrial zones or CO₂ sources.
Put together, these gains change the balance of project finance. E‑methanol plants that once looked like flashy demonstrators can start to look like assets with a clear path to profitability, especially in sectors under regulatory pressure to cut emissions.
A market racing toward €57 billion
The timing favours anyone who can deliver. Global synthetic fuel revenues are projected to jump from around €21 billion in 2025 to close to €57 billion by 2030, an annual growth rate of roughly 22%. Liquid e‑fuels sit at the heart of that surge.
Unlike hydrogen gas, e‑methanol can be stored and transported using existing infrastructure. It slots into tanks, pipes and ships that were designed for conventional fuels, and can be blended or converted into other products.

|---|---|
| 2025 | ≈ €21 billion |
| 2030 | ≈ €57 billion |
Europe stands out as one of the main drivers, backed by climate policies, low‑carbon hydrogen investments and industrial alliances. Maritime shipping and aviation — two sectors with limited direct electrification options — are emerging as natural customers for e‑methanol and its derivatives.
Industrialisation already under way
KHIMOD has not waited for all three patents to be fully processed before moving. Two industrial projects based on its e‑methanol technology have already been launched, suggesting that clients see enough evidence in the THOR results to commit real money.
That acceleration rests on a more comfortable financial base. In June 2025, the company raised €23 million, with backing from France’s state-backed fund Bpifrance, Audacia’s industrial decarbonisation fund and long-term shareholder ALCEN. The new capital helps shift the focus from R&D towards engineering, deployment and international partnerships.
The THOR pilot has been used as a proof point to justify full-scale design work and early commercial contracts.
French industry, often accused of lagging in next‑generation energy technologies, suddenly finds itself holding critical IP in a market with strong global demand.
A building block for multiple low‑carbon molecules
While e‑methanol sits at the core of KHIMOD’s current push, the company is positioning its milli‑structured reactors as a platform for a range of low‑carbon molecules.
Its R&D programmes also cover:
- E‑methane – synthetic natural gas, compatible with existing gas grids.
- E‑kerosene – a drop‑in synthetic jet fuel produced via intermediate molecules like methanol.
- Power‑to‑gas solutions – routes that convert surplus renewable electricity into storable gases via hydrogen and CO₂.
All rely on the same fundamental approach: using captured CO₂ and low‑carbon hydrogen as feedstocks, and managing intense heat release during synthesis reactions with high‑performance heat exchangers.
The fine chemicals industry also pays close attention to these concepts. Many high-value reactions are limited by temperature control. Reactors that can keep tight thermal boundaries while remaining compact offer an edge in both safety and product quality.
Why this technology matters for shipping and aviation
Shipping and aviation are at the sharp end of climate regulation, with new emissions rules forcing operators to look beyond fossil fuels. E‑methanol gives them a practical path because it behaves like a conventional liquid fuel, yet can be produced with radically lower lifecycle emissions.
For ships, methanol engines are already entering service, and ports are testing new bunkering infrastructure. For aviation, e‑methanol acts as an intermediate: it can be upgraded into synthetic kerosene that meets current jet fuel standards.
A high-pressure, high-yield process like KHIMOD’s changes how these fuels might roll out. Smaller, modular plants can be placed near ports, airports or industrial CO₂ sources, reducing logistics and tying production directly to local decarbonisation strategies.
Risks, constraints and real-world limits
The technology does not solve everything. E‑methanol remains constrained by access to cheap, abundant low‑carbon electricity, since both hydrogen production and CO₂ capture demand energy.
There are also safety and cost questions around operating at 300 bar, a pressure level that requires robust equipment, expert maintenance and careful design of every connection and seal. Insurance, standards and certification processes will influence how quickly projects scale.
On the climate side, the upstream footprint matters. If the electricity that feeds electrolysers is not genuinely low‑carbon, e‑methanol risks becoming another green‑tinted product without real emissions benefits.
Key terms and practical scenarios
For readers trying to map this landscape, a few definitions help:
- E‑fuels: fuels made from electricity, typically by combining hydrogen (from water electrolysis) with captured CO₂.
- E‑methanol: an e‑fuel where the final molecule is CH₃OH, used as fuel or chemical feedstock.
- Power‑to‑gas/liquid: processes that convert electricity into gaseous or liquid energy carriers.
Imagine a coastal industrial hub in 2030. A wind farm feeds an electrolyser that produces hydrogen. Nearby factories capture part of their CO₂ emissions. Both streams go into a KHIMOD-style high‑pressure unit that produces e‑methanol. Part of that output fuels local container ships, another part is upgraded into e‑kerosene for short‑haul flights, and the rest flows to chemical plants that replace fossil methanol in their products.
This kind of configuration links electricity markets, industrial emissions and transport fuel supplies. Gains in reactor efficiency, like those promised by KHIMOD’s milli‑structured technology, ripple through the chain: fewer wind turbines needed per tonne of fuel, smaller plant footprints, and a clearer case for financiers looking at 20‑year assets.
The three French patents do not lock in that future on their own, but they sharpen the tools available to engineers and investors who want low‑carbon molecules that actually work in the messy constraints of ports, pipelines and balance sheets.
