May 6, 2025. Cowboy Clean Fuels (CCF), a Wyoming-based climate tech and energy transition company, announced a groundbreaking offtake agreement with Mercuria, one of the world’s leading independent energy and commodity trading groups. This partnership marks the first commercial agreement for the sale of Renewable Natural Gas (RNG) generated under CCF’s pioneering BiCRS+RNG Methodology at the company’s Triangle Unit Project near Gillette, Wyoming.
Under the agreement, Mercuria will purchase the Environmental Attributes (EAs) associated with Cowboy’s carbon-negative RNG and distribute them through its global network of energy transition customers. The agreement covers an initial term of 10 years and represents the offtake of 5 million MMBTU equivalent EAs.
“Cowboy is excited to partner with Mercuria, who we consider the global leader in energy and environmental commodities,” said Ryan Waddington, CEO of Cowboy Clean Fuels. “This landmark agreement supporting offtake from our first commercial project is a game-changer for our company, and we look forward to working with Mercuria for years and years to come.”
“Mercuria has been looking for the next generation of RNG projects and technology to support the next phase of growth in the global RNG market,” said Harrison Clay, Head of Biogas, Mercuria. “When we found Cowboy, we immediately recognized they had the technology and growth potential necessary to carve out a leadership position in this market. We are thrilled to be their go-to-market partner.”
With additional RNG projects in development across Wyoming’s Powder River Basin and beyond, Cowboy Clean Fuels is positioned to become a leading supplier of carbon-neutral and carbon-negative fuels at scale.
