The Bureau of Land Management is seeking public comment on a proposal to create a massive carbon dioxide (CO2) storage project in southwestern Wyoming.

On July 1, 2024, the Bureau of Land Management announced an open public comment period on a draft environmental assessment of Moxa Carbon's application for a project meant to permanently store carbon dioxide (CO2) in 605,100 acres of underground geological formations owned by the federal government beneath Lincoln, Sweetwater, and Uinta counties.

The application was originally submitted by Tallgrass High Plains Carbon Storage, with the applicant changed to Leawood, Kansas-based Moxa Carbon in February 2023. The company is proposing using non-federal land for its CO2injection wells. The wells would require permits from the Wyoming Department of Environmental Quality, according to the bureau.  The application to use federal CO2 storage space is the “first step in a larger project that will consist of CO2 capture infrastructure at planned ammonia production facilities and other potential CO2 source points, CO2 compression and pumps, a CO2pipeline, and sequestration surface facilities,” according to a Moxa Carbon letter cited in the environmental assessment.

Written comments can be submitted until July 30, 2024. See the announcement for more information.
