The Illinois Basin - Decatur Project (IBDP) has reached its halfway point, injecting 500,000 metric tons of carbon dioxide into a saline reservoir at the Archer Daniels Midland facility in Decatur, Illinois. Injection of supercritical carbon dioxide began in November 2011 at a rate of 1,000 metric tons per day. The project goal is to inject 1 million metric tons by the end of 2014. Injection is at a depth of 7,000 feet and a full environmental monitoring program in the subsurface and at the surface has shown the injection reservoir and seal are performing as well as, if not better than, expected based on preinjection evaluations.

The IBDP is a U.S. Department of Energy (DOE)-funded project demonstrating the commercial viability of carbon capture and storage (CCS) in the Illinois Basin. The IBDP, conducted by the Midwest Geological Sequestration Consortium, is part of the development phase of the DOE’s Regional Carbon Sequestration Partnerships initiative, whereby CCS technologies are being developed and validated as part of a national strategy to reduce greenhouse gas emissions and mitigate climate change.
