What Frontline BioEnergy does

Frontline BioEnergy, LLC is a privately held thermochemical engineering and project development firm headquartered in Nevada, Iowa, that designs and licenses proprietary biomass gasification and pyrolysis systems for converting agricultural residues and waste streams into renewable fuels and products. The company's technology portfolio centers on six branded platforms — TarFreeGas® (pressurized fluidized bed gasifier producing up to 99% lower tar syngas), PMFreeGas® (pressurized bubbling fluidized bed gasification), PerfectGas™ (gas cleaning), ALKOOL™ (alkali removal), BING™ (biomass-to-natural-gas with catalytic methanation), and CLEANGAS® — protected by three granted US patents, with an additional autothermal pyrolysis (ATP) platform licensed from Iowa State University. End products include renewable natural gas (RNG), renewable hydrogen, renewable methanol, and biochar, with the largest biomass gasifier in North America operated at the company's Iowa pilot facility.

The company monetizes its technology through four revenue streams: technology licensing and royalties (notably to SGC Energia), project development with equity participation (the San Joaquin Renewables RNG project in California is designed to process 400,000-500,000 tons of agricultural waste annually into 4.5 billion cubic feet of RNG), engineering services and EPC contracts, and proprietary equipment sales. GTM is enterprise field-sales targeting ethanol producers, electric utilities, large agricultural operations, and municipal waste handlers. Key customers and partners include founding majority shareholder Chippewa Valley Ethanol Company (CVEC), Stine Seed Farms, Southern California Gas Co. (SoCalGas), Southern Energy Renewables, Nebraska Public Power District, and ION Clean Energy for carbon capture integration.

The company was originally formed in 2003 in Colorado and restructured as an Iowa LLC in November 2005; it secured a Series A from CVEC in 2009 and a Series B from SGC Energia in 2011, plus a $4.2M DOE grant (2013), a $1M XPRIZE Carbon Removal prize (2022), and $165M of project equity for San Joaquin Renewables from Cresta Fund Management in 2021. In December 2025 the company completed a reorganization establishing Frontline Group LLC as the new operating entity doing business as Frontline BioEnergy.
