This project will establish the feasibility of developing a commercial-scale (~50 million metric tons) geological carbon dioxide (CO2) storage complex at the Wabash Valley Resources facility near Terre Haute, Indiana.

The former Wabash integrated gasification combined cycle plant at this location has been repurposed as an ammonia production facility and will serve as the primary source of CO2 for the storage complex. The Mt. Simon sandstone is expected to be the primary storage reservoir; this and other potential storage reservoir(s) and sealing units at the prospective site will be characterized by a two-year data acquisition program that includes drilling and testing a new stratigraphic test well, core and fluid sample collection/analysis, and a two-dimensional seismic survey over the area.

Also evaluated will be the utilization of CO2 from the Wabash facility for enhanced oil recovery (EOR) in the Illinois East Basin.
