A feasibility study was conducted by the Kansas Geological Survey and the University of Kansas for a commercial-scale CCS project in Kansas.

This feasibility study examined three of Kansas’ largest CO2 point sources, nearby storage sites, and prospective CO2 transportation networks.

Westar Energy’s Jeffrey Energy Center near St. Marys, Kansas served as the primary site because of its size (2.16 GigaWatt and 12.5 million metric tons of CO2 emissions) and strategic location along the eastern margin of Kansas’ aerially extensive and vertically stacked, reservoir complexes.

Sunflower Electric Cooperative’s Holcomb coal-fired plant near Garden City in southwest Kansas and  CHS Refinery, near McPherson in central Kansas were secondary sites.

The Kansas City Board of Public Utilities with coal- and natural gas-fired plants in the Kansas City area participated providing optional sites and an additional perspective from a large metropolitan area.

The study concluded in 2018 that Kansas is a viable option for a commercial-scale carbon capture and storage (CCS) development because the size distribution of its oil fields provides deep saline aquifers near existing large point sources of CO2.
