Gevo Carbon Capture

The Gevo Carbon Capture project permanently sequesters carbon dioxide generated during ethanol production at a 50-million-gallon-per-year corn ethanol plant near Richardton, North Dakota. CO2 produced during fermentation is captured, purified to greater than 99.9% purity, compressed, dehydrated, and subcooled into liquid form before being injected underground into the Broom Creek geological formation on-site. In the project's absence, this CO2 would be released directly into the atmosphere as a byproduct of fermentation. The project is situated on an approximately 25-acre plant campus within a 135-acre parcel acquired by Red Trail Energy LLC in 2004 and 2005, with the facility having operated since January 2007. This carbon capture and storage project converts an existing emissions source into a vehicle for permanent geological sequestration, locking biogenic CO2 underground in a stable deep rock formation and preventing its contribution to atmospheric greenhouse gas concentrations.
