New mSAF: aviation fuel from methane, on the same catalyst platform that makes eSAF. Read the introduction
Infinium Energy

One catalyst platform. Two ways to make jet fuel.

Infinium turns waste carbon dioxide and renewable power into drop-in fuels. Now it does the same with methane. Both routes finish in the same reactor and produce fuel that meets the specifications aviation already flies on today.

Infinium production pathways Two feedstock routes converge on one reactor. Renewable power and waste carbon dioxide feed the React reverse water-gas shift step. Renewable power and methane feed the Reform electrified reforming step. Both produce syngas, which passes through Synthesize, Infinium's chain-limiting catalyst step, to yield eSAF, mSAF, eDiesel, eNaphtha and Edge immersion fluids.

Products

Five products, one catalyst platform. Each replaces a fossil molecule the market already buys.

Fuels and chemicals that need nothing new to work

Infinium products are not blendstocks that need a new engine, a new tank or a new pipeline. They are the same hydrocarbons the world burns and builds with today, assembled from waste carbon and renewable electricity instead of crude oil. That is why they can go to work now, at commercial volume, in fleets that already exist.

mSAF extends the platform to a feedstock that is already at the wellhead.

Introducing Infinium mSAF

New

eSAF answers the question of how to make jet fuel without oil. mSAF answers a different one: how to make a great deal of it, quickly, in the places where the feedstock is already stranded.

mSAF is sustainable aviation fuel produced from methane — pipeline natural gas, associated gas that would otherwise be flared, renewable natural gas from landfill and digester sites. The gas is reformed into syngas in Infinium Reform™, our electrified steam reformer, then converted to finished jet fuel in the same Synthesize™ step that makes eSAF. No electrolyser. No large carbon capture plant. The same catalyst, the same reactors, the same product specification at the outlet.

Sited where gas already is

Basins with associated gas, RNG clusters and gas processing hubs become fuel production sites without waiting for new renewable build-out.

Lower cost per gallon

Removing the electrolyser removes the single largest capital and power cost in the power-to-liquids stack.

Same molecule at the outlet

Synthetic paraffinic kerosene with no sulfur and very low aromatics — the fuel handling chain cannot tell the difference.

Technology

Three systems, licensable individually or as one integrated plant.

The plant is the product too

Infinium sells fuel, and it sells the means of making it. Each of the three core systems has been operated at commercial scale, and each can be licensed with its catalyst and core equipment into an existing refinery, gas plant or greenfield site.

Syngas production equipment at an Infinium facility

Infinium React™

Reverse water-gas shift. Waste CO₂ and hydrogen become low-carbon syngas. Operating commercially since 2023 — the first plant of its kind anywhere.

Liquid fuel production reactors

Infinium Synthesize™

A chain-limiting catalyst that produces finished liquid fuel directly, rather than the wax a conventional Fischer-Tropsch train yields. No wax refining, no trip to a refinery.

Infinium Reform™

The world's first commercial-scale electrified steam methane reformer, and the world's largest now under construction. Power replaces fired heat, which removes the combustion emissions that make conventional reforming carbon-intensive.

Company

Founded 2020. Headquartered in Sacramento, California.

A decade of catalyst work

The chemistry behind Infinium was refined over more than ten years before anything was built at commercial scale. That order matters: the company reached commercial operation because the catalyst and reactor work was finished first, not because a demonstration was scaled on hope.

Infinium is backed by strategic and financial investors across North America, Europe and Asia, including Brookfield, Breakthrough Energy Catalyst, Amazon, NextEra Energy Resources, Mitsui & Co., Mitsubishi Heavy Industries, Mitsubishi Corporation, SK, AP Ventures and Sumitomo Mitsui Trust Bank.

What are you trying to decarbonise?

Airlines buying fuel, industrial operators sitting on a CO₂ or gas stream, and licensees who want to build their own plant all start in the same place: a conversation about volumes, timing and site.

More than a quarter of the world's carbon dioxide emissions come from the planes, ships and trucks that move goods and people. Those engines are not going away this decade. The fuel in them can.
