Cowboy Clean Fuels, founded in 2020 and led by CEO Ryan Waddington, develops carbon-negative renewable natural gas (RNG) using depleted Coal Bed Methane wells and existing infrastructure. The company converts agricultural byproducts into CO2 and renewable methane via a biogenic process in deep geologic coal formations in Wyoming's Powder River Basin. Its commercialization approach is branded as "Biomass with Carbon Removal and Storage, plus Renewable Natural Gas (BiCRS+RNG)." CCF positions this technology as a scalable, capital-efficient solution in the renewable energy sector. The company is advancing its first commercial project, the Triangle Unit Renewable Energy and Carbon Capture and Storage (TRECCS) Project in Wyoming. Recent financing will be used to support development and commercialization of that project. Cowboy Clean Fuels develops a patented process that permanently sequesters atmospheric CO2 and produces carbon‑negative renewable natural gas from agricultural byproducts using non‑producing coal bed methane (CBM) wells and existing infrastructure. The company’s technology was developed by its CTO, Dr. Michael Urynowicz, and is exclusively licensed from the University of Wyoming’s Center for Biogenic Natural Gas Research. Its first commercial project, the Triangle Unit Renewable Energy and Carbon Capture and Storage (TRECCS) project in Wyoming, received a Class V Underground Injection Control permit in late 2023 and is permitted to sequester CO2 and produce RNG at commercial volumes. When fully operational the TRECCS project is expected to generate roughly 185,000 metric tons of verifiable carbon dioxide removal (CDR) credits per year and produce about 0.7 billion cubic feet of RNG annually. CCF was formed in 2020 and maintains offices in Denver, Colorado and Gillette, Wyoming; its leadership team collectively has over 100 years of experience in relevant energy sectors. The company is positioning to commercialize and scale the TRECCS technology across the Powder River Basin to restore value to existing CBM infrastructure and expand RNG and CO2 sequestration capacity. Cowboy Clean Fuels develops patented technology to produce carbon-negative renewable natural gas (RNG) from waste agricultural byproducts by stimulating a naturally occurring biogenic process in deep geologic formations. The company repurposes non-producing coal bed methane (CBM) wells and existing infrastructure to generate renewable methane through a process similar to anaerobic digestion. Its proprietary technology was developed and exclusively licensed from the University of Wyoming’s Center for Biogenic Natural Gas Research by co‑founder and CTO Dr. Michael Urynowicz. Cowboy Clean Fuels says the process not only produces RNG but also removes and permanently sequesters atmospheric CO2. Leadership brings more than 100 years of combined experience in clean energy commercialization, upstream gas operations, and large-scale project development. The company is preparing for an initial commercial-scale project launch in the Powder River Basin of Wyoming and is pursuing regulatory and engineering milestones ahead of scale-up.
