The U.S. Environmental Protection Agency has taken a significant step toward bringing carbon capture and storage to Kansas, tentatively approving a plan by ethanol producer PureField Ingredients to permanently store carbon dioxide beneath the state’s central plains.
The draft permit would allow a PureField subsidiary to inject up to 1.8 million metric tons of carbon dioxide into deep rock formations in Russell County over a 12-year period. The emissions would come from the company’s nearby ethanol facility and be transported by pipeline to a Class VI injection well drilled roughly 3,500 feet underground.
If finalized, the permit would mark the first approval of its kind in Kansas, signaling growing federal support for carbon sequestration projects tied to biofuels. The EPA’s review found that the targeted storage zone is separated from drinking water supplies by thousands of feet of dense rock layers, reducing the risk of contamination.
The California connection
For PureField, the project is designed to lower the carbon intensity of its fuel, a key requirement for selling into premium markets such as California’s low-carbon fuel program. Federal tax incentives, including credits for carbon capture and clean fuel production, have become central to the economics of such projects.

Kansas is not alone in exploring underground carbon storage. The EPA is reviewing additional applications from ethanol producers in the state, reflecting a broader Midwest push to pair agriculture-based fuels with climate technology. Ethanol plants are considered particularly attractive candidates for carbon capture because fermentation produces a relatively pure stream of carbon dioxide, keeping costs lower than in other industrial settings.
Nationally, carbon capture has gained renewed attention as policymakers look for ways to cut emissions without shutting down existing industries. Projects are already operating in Illinois and North Dakota, while new pipeline networks are emerging to move carbon dioxide across state lines for storage or enhanced oil recovery.
The Kansas proposal fits into a wider U.S. effort to scale carbon sequestration, an approach many energy analysts view as essential for meeting long-term climate goals while sustaining domestic fuel production.
