Carbon America said Jan. 23 it has entered the technical review phase in the process to obtain federal permission to permanently store CO2 produced by two ethanol plants in Colorado.

The Colorado-based company said it submitted its application for a Class VI CO2 injection well permit to the U.S. Environmental Protection Agency on Dec. 4. If given the green light on the Denova project, Carbon America said it plans to permanently store up to 350,000 metric tons per year of carbon produced annually at the Yuma and Sterling ethanol plants in northeastern Colorado.

The amount is equivalent to removing about 70,000 passenger vehicles from roadways, the company said.

“The application is the culmination of years of technical analysis and data collection enabled by our deep subsurface and regulatory expertise,” Carbon America CEO Brent Lewis said.

The Denova project is expected to capture 95% of annual CO2 emissions from the fermentation process at the plants before it can be released into the atmosphere, the company said in a news release. The carbon will then be transported via underground pipeline to the permanent geologic storage site about 5,000 ft below surface.
