A biomass carbon removal and storage pathway built on Wyoming's subsurface

Cowboy Clean Fuels operates a biomass carbon removal and storage (BiCRS) pathway in Wyoming's Powder River Basin. Agricultural processing residues are injected into depleted coalbed methane reservoirs, where indigenous microorganisms anaerobically digest the biomass, generating renewable natural gas while carbon dioxide is permanently absorbed onto the coal surfaces. Carbon removal is quantified under the company's patented BiCRS+RNG methodology, developed to ISO 14064-2:2019, with permanence of more than 100 years.

Cowboy Clean Fuels' projects are certified under the Absolute Carbon Standard, developed by Absolute Climate, with credits issued through the C-Capsule registry operated by Evident, part of Xpansiv. Climate Vault Solutions has independently assessed the company's Triangle Unit project following a multi-phase technical review.

The Powder River Basin's extensive coalbed methane infrastructure and unmineable seam inventory give the pathway a distinctive combination: durable geologic storage, renewable gas production, and a resource base measured in decades rather than project cycles. Cowboy Clean Fuels operates the only patented BiCRS + RNG pathway currently available to buyers.

"Durable carbon removal needs pathways that can be verified today and expanded tomorrow, and Wyoming's subsurface gives us both. Buyers working with us get permanent removal alongside carbon-neutral renewable gas from the same operations, a combination very few suppliers can offer. This is an important step for Cowboy Clean Fuels and for the rural communities in Campbell County, Wyoming, that make the work possible."

— Ryan Waddington, Chief Executive Officer, Cowboy Clean Fuels

The purchases are part of Salesforce's pledge to contract USD 100 million in durable carbon removal by 2030.

Wyoming and Campbell County

Cowboy Clean Fuels' operations build on existing coalbed methane infrastructure and the operational expertise of Wyoming's energy workforce, putting legacy assets to productive use. The project supports skilled employment in Campbell County and generates new revenue from infrastructure already in place.

Durable carbon removal and renewable natural gas add markets for the region's existing resources and workforce, supporting economic diversification in Campbell County and across Wyoming. Cowboy Clean Fuels views its partnership with the county and the state as foundational to its long-term success.

Availability

Cowboy Clean Fuels is developing additional projects in the Powder River Basin and is currently contracting durable carbon removal volumes and carbon-neutral RNG supply. Verified credits are listed on-registry and available for immediate purchase. The company's goal is to become a leading provider of permanent, geologically stored carbon removal in the United States, using Wyoming's infrastructure, subsurface resources, and energy workforce to deliver verifiable durable CDR over the coming decades.
