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

Five products. Nothing new required to use them.

Infinium makes the molecules industry already runs on, assembled from waste carbon and renewable electricity instead of crude oil. Same specification, same engines, same tanks, same pipelines.

Portfolio

Two aviation fuels, two industrial products, one dielectric fluid.

Aviation, long-haul road freight, shipping and petrochemicals are the sectors where electrification runs out of road. They need energy-dense liquid hydrocarbons, and they need them in the fleets and plants that exist today. Every Infinium product is built for that constraint first. Nothing here asks a customer to buy a new aircraft, retrofit an engine or lay new pipe.

Alongside the fuels, Infinium Edge™ Immersion Fluids apply the same synthetic chemistry to a different problem: cooling the compute density that modern AI hardware demands.

Infinium eSAF

Flying today

Aviation carries billions of passengers and millions of tonnes of freight a year, and there is no electric or hydrogen aircraft on the horizon that changes that at scale this decade. Sustainable aviation fuel is still under one per cent of the roughly 100 billion gallons of jet fuel the world burns annually.

eSAF closes that gap without touching the aircraft. It is a synthetic paraffinic kerosene made from waste carbon dioxide and renewable electricity, energy-dense, cleaner-burning, and low in the sulfur and aromatics that drive soot and particulate formation in a turbine.

In August 2026 eSAF produced at Project Pathfinder flew an American Airlines passenger service from Corpus Christi to Dallas Fort Worth — the first US commercial passenger flight powered by electrofuel.

Infinium mSAF

New

mSAF is aviation fuel made from methane rather than carbon dioxide. Pipeline natural gas, associated gas that would otherwise be flared, and renewable natural gas from landfill and digester sites are reformed into syngas in Infinium Reform™, then converted to finished jet fuel in the same Synthesize™ step that produces eSAF.

The point of mSAF is volume and siting. Removing the electrolyser removes the largest single capital and power cost in a power-to-liquids plant, which means projects can be built where gas is already stranded and where the renewable grid is not yet large enough to support electrolysis at scale.

Typical properties and commercial status
Product typeSynthetic paraffinic kerosene
SpecificationMeets existing aviation turbine fuel specifications, within approved blend limits
Carbon intensityDepends on gas source and power supply. See carbon intensity
SulfurNone
AromaticsVery low

Infinium eDiesel

In delivery

Medium and heavy trucks, locomotives and ships are the workhorses of the global economy and they consume enormous volumes of petroleum diesel and fuel oil. Freight volumes are forecast to keep rising, and the fleets turning over today will still be running in the 2040s.

eDiesel drops into those engines now. It has high cetane and no sulfur, which means it burns more cleanly than the fuel it replaces and releases fewer of the air toxins that concentrate around ports, rail yards and freight corridors. Amazon has been running eDiesel from Pathfinder in delivery operations since the plant started up.

Typical properties and commercial status

Infinium eNaphtha

In delivery

Naphtha is the feedstock beneath an enormous share of everyday material life: medical devices, water infrastructure, packaging, electronics, footwear. It is also one of the most greenhouse-gas intensive inputs in manufacturing, because it comes out of a crude oil refinery.

eNaphtha replaces it directly in a steam cracker with no reformulation. It contains no aromatics and has high paraffin content, which makes it a clean cracker feed, and it carries negative carbon intensity at the plant gate. Borealis uses Infinium eNaphtha to make low-carbon polymers, and On's CleanCloud midsole — the first EVA midsole made from captured carbon at commercial scale — is built on it.

Typical properties and commercial status

Infinium Edge™ Immersion Fluids

Sampling

AI accelerators have crossed a thermal threshold. Air cooling has run out of headroom, direct-to-chip extended the runway, and the next generation of silicon will push past that too. Meanwhile cooling energy and water consumption have become the binding constraints on where a data centre can be built at all.

Edge Immersion Fluids are single-phase dielectric liquids formulated through the same synthetic chemistry as the fuels. They are non-conductive and non-corrosive, thermally stable, and compatible with common data centre materials, so heat is carried away from the die with no chillers, no hot aisle and no evaporative water loss. Because the base molecules come off Infinium's power-to-liquids platform, the fluid carries a carbon-negative lifecycle rather than the high global warming potential of fluorinated coolants.
