The U.S. Environmental Protection Agency has granted a permit for a proposed carbon capture and storage (CCS) project in northeastern Indiana. The project, called One Carbon Partnership, is a joint venture between Denver-based Vault 44.01 and Cardinal Ethanol. The facility will be located about 95 miles northeast of Indianapolis along the Indiana-Ohio border.

Why it matters

CCS technology is seen as a critical tool in reducing greenhouse gas emissions and combating climate change. This project represents an important step forward in deploying CCS infrastructure in the Midwest, a region with significant industrial and agricultural emissions that contribute to the nation's carbon footprint.

The details

The One Carbon Partnership CCS project will involve capturing carbon dioxide emissions from Cardinal Ethanol's existing biofuel production facility and permanently storing the CO2 underground in deep geological formations. The EPA permit allows the companies to proceed with construction and operation of the injection wells and associated infrastructure needed for the carbon sequestration process.

  • The EPA granted the permit on April 14, 2026.
  • Construction on the project is expected to begin later this year.
