What Primus Green Energy does

Primus Green Energy, now operating as Verde Clean Fuels, is a U.S.-based clean fuels technology company that has developed a proprietary process, STG+ (syngas-to-gasoline plus), to convert natural gas, biomass, and municipal solid waste into commodity-grade RBOB gasoline (or methanol) as a finished end product. The technology operates through two demonstrated pathways: a natural gas-to-gasoline pathway that produces gasoline approximately 30% less carbon-intensive than conventional gasoline while mitigating flaring in oil-producing regions, and a biomass-to-gasoline pathway that yields carbon-negative gasoline from agricultural byproducts. The company has validated the platform through more than 10,000 hours of demonstration plant operations and deploys modular, scalable facilities sited near abundant, low-cost feedstocks.

The business model is B2B enterprise, targeting oil and gas producers seeking to monetize stranded or flared associated gas (primary segment) and biomass suppliers and agricultural operations seeking higher-value outlets for agricultural byproducts (secondary segment). Go-to-market is direct enterprise sales with long-cycle offtake and facility-deployment negotiations. Strategic partners include Diamondback Energy (a Permian Basin E&P and likely deployment/offtake partner), KOCH Modular (modular fabrication), The Shaw Group (EPC services), and Bluescape Energy (strategic/capital partner). Pricing is custom and not publicly disclosed, consistent with project-based, capital-intensive facility deployment and commodity-linked product sales.

The company is privately held, headquartered in Houston, Texas (711 Louisiana Street, Suite 2160), employs 51-100 people, and has raised approximately $59 million across four funding rounds between 2007 and 2013. As of the available data, no commercial-scale revenue has been disclosed, and the company is positioned at the pre-commercial-to-early-commercial transition, with the recent rebrand and partner buildout consistent with a deliberate pivot from long-duration R&D to market entry.

Revenue model

1. Gasoline Sales: Sale of low-carbon gasoline produced from natural gas or biomass feedstocks. The company operates demonstration facilities and is commercializing its technology for deployment at scale. Revenue is generated through the sale of commodity-grade RBOB gasoline and potentially methanol as end products.

Core offering

Primus Green Energy (now operating as Verde Clean Fuels) develops and commercializes the proprietary STG+ (Syngas-to-Gasoline Plus) technology platform, a modular and scalable system that converts diverse feedstocks — natural gas, biomass, and municipal solid waste (MSW) — directly into end-product gasoline or methanol. The company operates two distinct pathways: a natural gas-to-gasoline pathway producing RBOB gasoline that is 30% less carbon-intensive than conventional gasoline, and a biomass-to-gasoline pathway producing carbon-negative renewable gasoline from agricultural byproducts. The technology is licensed and deployed through modular facilities built near low-cost feedstock sources.

Product overview

Verde Clean Fuels (formerly Primus Green Energy) offers the STG+® (syngas-to-gasoline plus) technology platform, a proprietary modular and scalable system that converts diverse feedstocks—biomass, municipal solid waste (MSW), and natural gas—into end-product gasoline or methanol. The company operates two distinct production pathways: the Natural Gas-to-Gasoline pathway produces 30% less carbon-intensive RBOB gasoline while addressing gas flaring issues, and the Biomass-to-Gasoline pathway produces carbon-negative renewable gasoline from agricultural byproducts. The company also operates a demonstration facility that has completed over 10,000 hours of operations.

Functional benefit

Products and services

• STG+ (Syngas-to-Gasoline Plus) Technology Platform Proprietary, patented modular and scalable technology platform that converts diverse feedstocks — biomass, municipal solid waste (MSW), and natural gas — into end-product gasoline or methanol, eliminating the need for further refining. Licensed and deployed through modular facilities built in feedstock-abundant regions. Target customers are oil and gas producers, agricultural operators, and biomass suppliers.
• Natural Gas-to-Gasoline Pathway STG+ production pathway that converts natural gas into commodity-grade RBOB gasoline that is 30% less carbon-intensive than conventional gasoline. Mitigates harmful flaring in oil-producing regions and enables oil and gas producers to monetize stranded or associated natural gas as a higher-value product while generating in-basin demand. For oil and gas producers with flared or stranded natural gas.
• Biomass-to-Gasoline Pathway STG+ production pathway that converts biomass feedstocks (such as agricultural byproducts) into renewable, low-carbon gasoline that is compatible with existing internal combustion engine vehicles and refueling infrastructure. When produced from gasified biomass, the gasoline is carbon-negative — putting more carbon in the ground than is released during consumption. For agricultural operators and biomass suppliers seeking to monetize byproducts.
• Low-Carbon RBOB Gasoline Commodity-grade RBOB gasoline end product produced via the STG+ platform from natural gas (30% less carbon-intensive than conventional) or biomass (carbon-negative) feedstocks. Distributed through existing fuel infrastructure networks for use in ICE vehicles, with lower life cycle carbon intensity than EVs.

Direct peers

• Velocys: Velocys develops microchannel Fischer-Tropsch reactors to convert natural gas and biomass into synthetic fuels — directly comparable to Verde's STG+ syngas-to-gasoline pathway, with a similar small-scale, modular commercialization approach.
• Fulcrum BioEnergy: Fulcrum converts municipal solid waste (MSW) into synthetic transportation fuels via gasification/FT — overlapping Verde's biomass/MSW-to-gasoline pathway and targeting the same waste-to-fuels decarbonization theme.
• SunGas Renewables: SunGas provides biomass gasification technology that produces syngas for downstream conversion to renewable fuels — directly comparable feedstock-to-syngas front-end of Verde's STG+ process.
• LanzaTech: LanzaTech uses gas fermentation to convert waste gases (including flared gas) into ethanol and chemical feedstocks — competing low-carbon pathway for stranded gas monetization that targets the same oil & gas customers as Verde.

Emerging players

• Prometheus Fuels: Prometheus produces gasoline (and jet fuel) from direct air capture of CO₂ combined with green hydrogen — an alternative net-zero gasoline pathway competing for similar low-carbon fuel mandates and offtake customers.
• HIF Global: HIF Global produces e-fuels (e-gasoline, e-diesel, e-SAF) from green hydrogen and captured CO₂ — an emerging alternative low-carbon fuel pathway competing for similar policy support and corporate offtake agreements.
• Sunfire: Sunfire produces e-fuels (synthetic diesel, gasoline, SAF) via high-temperature electrolysis and reverse water-gas-shift — an emerging competitor pursuing synthetic low-carbon fuels with overlapping feedstock-to-liquid-fuel chemistry.

Broad incumbents

• Aemetis: Aemetis produces renewable diesel and sustainable aviation fuel from biomass feedstocks — a broader incumbent in the low-carbon fuels space, targeting similar decarbonization mandates as Verde's biomass-to-gasoline pathway.
• Sasol: Sasol operates large-scale gas-to-liquids (GTL) facilities producing synthetic fuels from natural gas via Fischer-Tropsch — a broader incumbent whose GTL technology competes in concept with Verde's modular syngas-to-gasoline approach.

Others

• Topsoe: Topsoe licenses syngas, hydroprocessing, and gas-to-fuels catalysts and technology — adjacent ecosystem participant whose technology could enable or compete with Verde's STG+ syngas-to-gasoline process.
