Interactive map of Class VI Wells for geologic storage of carbon dioxide 

November 16, 2023 Work Area: Carbon Capture

Recent policy advances in the U.S. have spurred significant expansion of investment in carbon capture and storage (CCS) technologies. CCS provisions in the Infrastructure Investment and Jobs Act and the Inflation Reduction Act included an expansion of the 45Q tax credit and funding opportunities for CCS projects and as a result, the number of announced CCS projects in the U.S. has skyrocketed to nearly 200. Nearly all these projects will require captured emissions to be permanently stored in deep geologic formations via Class VI wells. 

Class VI wells are a type of well used for geologic storage of carbon dioxide that EPA regulates under its Underground Injection Control Program. Class VI wells are an integral part of the CCS value chain and are critical for capture projects to realize their climate benefit. The rise in announced CCS projects and investment has resulted in a massive increase in Class VI well applications to EPA and states that have primacy for permitting Class VI wells. As of November 2023, there are 187 Class VI wells that are either currently under review or have been permitted between EPA regional offices and state primacy programs.  

Use CATF’s interactive map below to track all the currently pending Class VI well applications and active Class VI wells in the U.S., as well as the current Class VI primacy status by state. Click on each colored state to learn about the Class VI well applications and project information. The map shows where Class VI wells are being planned around the country, and we will regularly update the map to reflect new applications as they are made available by EPA and states.
