CHEYENNE - The U.S. Department of Energy has awarded nearly $67 million for a test project to store more than 2 million tons of carbon dioxide underground in western Wyoming.
The money is going to the Big Sky Regional Carbon Sequestration Partnership as part of a series of government projects to study injecting greenhouse gases underground.
The Energy Department says successful carbon sequestration would help the United States use its fossil fuel resources without contributing to global climate change.
Montana State University is leading the project, which involves drilling a CO2 injection well into the Nugget Sandstone formation near Big Piney, in Sublette County.
Cimarex Energy Co. will provide CO2 for the project from its Riley Ridge plant, a gas-processing facility currently under development.
