Project Bison, also known as also known as Wyoming Regional Direct Air Capture Hub, included the development of a large DAC facility in Wyoming. The project was canceled in September 2024 because of “growing competition for clean power amongst industries that are emerging much faster than anybody would have ever predicted.”

Its build-out was supposed to follow a phased rollout plan to capture and store five million tons of atmospheric CO2 per year by 2030. The project was expected to be the first commercial-scale project to utilize Class VI injection wells to permanently store CO2 captured from ambient air using DAC technology.

CarbonCapture was developing the project alongside anchor CO2 storage partner Frontier Carbon Solutions and anchor CO2 utilization partner Twelve. The team also included supporting partners the University of Wyoming, Fluor, Carbon Direct, INTERA, EPRI, Carbon-Based Consulting, Icarus, and Novus Energy Advisors.
