About the company
Circularity Fuels, Inc., a veteran-owned manufacturer headquartered in Redwood City, California, is a federal grant recipient developing sorbent-enhanced catalytic reactor systems for synthetic natural gas and high-purity methane production serving energy and advanced materials sectors. The company operates exclusively as a prime recipient on early-stage research cooperative agreements and project grants; it holds no federal contracts and carries no subcontract exposure.
Circularity Fuels' capability portfolio centers on catalytic gas conversion, specifically sorbent-enhanced catalysis reactors that convert CO2 and hydrogen into methane and synthetic natural gas at scale. The company's federal footprint comprises three awards spanning two agencies. The Department of Energy Advanced Research Projects Agency awarded a $4 million Cooperative Agreement on March 3, 2026 (CFDA 81.135) to design and build a 5-megawatt subunit for a utility-scale reactor system that converts electricity or hydrogen into synthetic natural gas by capturing and converting atmospheric carbon; this award runs through March 2, 2029, and represents the company's largest active commitment. The National Science Foundation awarded two grants under the Technology, Innovation, and Partnerships program (CFDA 47.084): a $1.25 million Small Business Innovation Research Phase II Cooperative Agreement on August 1, 2026, to develop a joule-heated sorbent-enhanced catalysis reactor for high-purity methane production serving semiconductor and advanced carbon material manufacturing (completing July 31, 2028), and a $275,000 Small Business Innovation Research Phase I Project Grant on September 15, 2024, to develop sorbent-enhanced catalytic processes for upgrading biogas from wastewater treatment facilities into renewable natural gas (completed August 31, 2025). All work is performed in Redwood City, California. Combined obligated dollars across all awards total $5.5 million. Within the next twenty-four months, one award—the NSF Phase I biogas project—reaches completion, creating no material recompete cliff for the vendor's current funding stream.
