Infinium

Infinium is a United States fuels company that makes drop-in fuels and chemicals from waste carbon dioxide, methane and renewable power. Its website says it was founded in 2020 and is headquartered in Sacramento, California, building on more than a decade of earlier work on catalysts, reactors and gas-to-liquids technology. The company says it has been in commercial production since 2023.

Products

• eSAF, a sustainable aviation fuel made from waste CO2 and renewable power, with a low carbon intensity and meeting ASTM specifications
• mSAF, aviation fuel made from methane such as renewable natural gas from landfills and digesters, and associated gas that would otherwise be flared
• eDiesel, described as high cetane and zero sulfur
• eNaphtha
• Edge immersion fluids, which carry heat directly off a chip die

All products are described as drop-in, meaning they work in the same engines, pipelines and tanks as the products they replace. Both the eSAF and mSAF routes use one catalyst platform and finish in the same reactor.

Plants and milestones

The company timeline lists Project Pathfinder in Corpus Christi, Texas, which it calls the first commercial-scale power-to-liquids plant in the world, and Project Roadrunner in Reeves County, Texas. It records the first US commercial passenger flight on eSAF, from Corpus Christi to Dallas Fort Worth, and a commitment by Brookfield to scale eSAF production. Infinium reports more than 300 patents worldwide covering power-to-liquids and gas conversion, extended by its 2025 acquisition of Greyrock Technology.

Business model and backers

Customers can buy fuel, partner on a project or license the technology to build their own capacity. Investors named on the site include Brookfield, Breakthrough Energy Catalyst, Amazon through its Climate Pledge, AP Ventures, Mitsubishi Heavy Industries, NextEra Energy Resources and SK.
