What Infinium does
Infinium is a clean fuel technology company headquartered in Sacramento, California, founded in 2020, that develops and deploys electrofuels (eFuels) produced from captured carbon dioxide and renewable power via power-to-liquid (PtL) chemistry. Its core platform, Infinium Energy™, encompasses proprietary reaction, synthesis, and reforming components branded React™, Synthesize™, and Reform™, along with the scalable gas-to-liquids solution Infinium GTL and acquired Greyrock Technology. Products include ultra-low carbon eSAF for aviation, eDiesel for heavy transport, and eNaphtha for chemical applications, targeting a 95% carbon intensity reduction versus fossil jet fuel. Project Pathfinder is the first commercial eFuels plant; Project Roadrunner in Pecos, Texas, is under construction targeting 23,000 tonnes/year of eSAF with commercial operations expected in 2027, and a 100MW green-hydrogen electrolyzer is supplied via Electric Hydrogen's modular HYPRPlant. Project Atlas is a joint submission with American Airlines that won the Sustainable Aviation Buyers Alliance next-generation SAF procurement award.
Infinium sells its fuels primarily through long-term (10-15 year) enterprise offtake agreements with major airlines structured to satisfy EU ReFuelEU and UK SAF Mandate compliance obligations and Scope 3 reduction commitments. Anchor customers include American Airlines (10-year deal via Citi Bank), International Airlines Group (10-year deal for the majority of Roadrunner output), and Loganair (15-year offtake). Distribution channels comprise direct domestic sales, UK compliance exports, and a book-and-claim model for EU RFNBO eSAF. In January 2026, Infinium launched a second platform, Infinium Edge™, providing immersion-cooling technology and proprietary dielectric fluids for high-density AI data center workloads, extending its chemistry expertise into the AI infrastructure supply chain.
Capital structure is dominated by Brookfield Asset Management, which led both a $1.1 billion growth investment in September 2024 and the Series C round in January 2025. Earlier investors include SK Trading International (2022), Climate Pledge Fund, NextEra, Mitsubishi Heavy Industries, AP Ventures, and Pavilion Capital (2021); later strategic investors include Mitsui (2025) and project financing from HSBC for Roadrunner One, LLC (2025). Operationally, Infinium runs a Texas pilot plant since 2023, is constructing Project Roadrunner, operates a manufacturing footprint at Pecos and Corpus Christi (in partnership with Howard Energy Partners), and runs a Singapore-headquartered development platform (eFuels SEA) targeting 3-5 commercial-scale facilities across Southeast Asia. The company is privately held (Infinium Holdings, Inc., Delaware) with a 51-100 employee headcount and remains pre-revenue, with first commercial eFuels output scheduled for 2027.

Revenue model
- Sustainable Aviation Fuel (eSAF) Sales: Production and sale of ultra-low carbon eSAF to airlines under long-term offtake agreements. Revenue is generated through volume-based sales of synthetic jet fuel produced from captured CO2 and renewable hydrogen. Fuels are sold domestically and exported to international markets including the UK for compliance with SAF mandates.
- eDiesel and eNaphtha Sales: Production and sale of synthetic diesel and naphtha products for transportation and industrial applications. These drop-in replacement fuels are compatible with existing fuel infrastructure and serve hard-to-decarbonize sectors.
- Infinium Edge Immersion Cooling Solutions: Dielectric fluid products and cooling technology solutions for AI data centers. Revenue generated from selling immersion cooling fluids and platform technology to data center operators.

Infinium product offering
Product offeringCore offering
Infinium produces ultra-low carbon synthetic electrofuels (eSAF, eDiesel, eNaphtha) by converting captured carbon dioxide and renewable electricity into green hydrogen and then into drop-in replacement fuels for aviation, heavy-duty transportation, and industrial applications. The company also sells Infinium Edge™ immersion cooling fluids and platform technology for high-density AI data center thermal management. Customers include major airlines via long-term offtake agreements, and the company constructs and operates its own commercial-scale production facilities.
Product overview
Infinium is a technology-driven company operating through two complementary platforms: Infinium Energy™ and Infinium Edge™. Infinium Energy™ is the core eFuels platform that converts captured carbon dioxide waste and renewable power (via green hydrogen) into ultra-low carbon electrofuels including eSAF (sustainable aviation fuel), eDiesel, and eNaphtha, delivered through projects including Project Roadrunner (world's largest eFuels facility in Texas), Project Pathfinder (first commercial plant), and Infinium GTL gas-to-liquids technology. Infinium Edge™ is the newer AI data center infrastructure platform launched in 2026 featuring immersion cooling technology and custom Infinium Edge Immersion Fluids™ for thermal management of high-density AI workloads. The React™, Synthesize™, and Reform™ components are technology building blocks within the energy solutions portfolio.
