Sacramento, Calif. – September 21, 2026 -- Infinium has introduced mSAF, a new product line that converts renewable natural gas, biogas, flare gas and other methane streams into low-carbon sustainable aviation fuel (SAF), extending the company's existing CO2-based eSAF business into a second feedstock category.
Infinium adds methane pathway to complement its CO2-based eSAF business
The mSAF platform targets methane already aggregated at landfills, dairies, wastewater facilities and gas-gathering systems across North America, Asia and Europe. CEO Robert Schuetzle said the offering lets Infinium apply its proven technology across a broader range of locations while delivering more low-carbon fuel alongside its growing eSAF operations.
Fischer-Tropsch and electrified reforming technology anchor both product lines
mSAF and eSAF share Infinium's Synthesize catalyst and reactor platform, which the company has operated commercially for more than a decade, along with common catalyst manufacturing, product specifications and certification pathways. The mSAF process adds Infinium's Reform electric steam methane reformer (eSMR), which the company is deploying at commercial scale at Project Roadrunner as what it describes as the world's largest eSMR installation.
Electrified reforming raises fuel yield versus conventional gas-fired systems
Conventional steam methane reforming burns part of the feed gas to generate process heat, adding combustion emissions and consuming feedstock carbon that could otherwise convert into fuel. Infinium's Reform technology instead uses renewable electricity for that heat, increasing fuel yield per unit of gas and avoiding reforming-related combustion emissions — a factor the company says directly improves project economics for RNG-based projects where feedstock cost and carbon intensity drive commercial viability.
RMI assessment flags need for rigorous lifecycle accounting on methane pathways
Infinium worked with independent research group RMI on an assessment of the mSAF market opportunity. RMI Managing Director Bryan Fisher said biogas and RNG pathways may offer climate and commercial value, but only with rigorous lifecycle accounting, auditable chain-of-custody systems and credible certification frameworks. Infinium said the mSAF designation does not imply a single carbon-intensity value across projects, since lifecycle emissions depend on methane source, leakage rate, production-energy mix and chain of custody; the company will calculate and independently certify carbon intensity at the project level under applicable regulatory and voluntary frameworks.
