Decatur Fact Sheet: Carbon Dioxide Capture and Storage Project

Company/Alliance: Archer Daniels Midland, MGSC (Led by Illinois State Geological Survey), Schlumberger Carbon Services and Richland Community College

Location: Decatur, Illinois, USA

Start Date: November 2011

End Date: September 2015

Size: 1 Mt/yr

CO2 Source: Ethanol plant (capture using Alstom’s amine process)

Storage: Sequestration in Mount Simon Sandstone



Total cost $208 million. DOE share $141.5 million (68%).

The project is to test the storage potential of the Mount Simon Sandstone and the integrity of the overlying sealant rocks.
Phase 1: DOE awarded $66.7 million of the $84.3 million needed for the project. The DOE announced on June 2010 that Decatur was one of 3 projects to receive up to $612 million from the American Recovery and Reinvestment Act - matched by $368 million in private funding - to demonstrate large-scale carbon capture and storage from industrial sources.


Decatur was initially selected in October 2009 for the DOE Phase 1 research and development grants. Following successful completion of the Phase 1 activities, it was identified as one of the most promising industrial CCS projects through a competitive process and entered into Phase 2 with additional funding to begin design, construction, and operation.
Phase 1 timing: Drilling began in February 2009 and a successful injection with a rate of 1000 tons per day was achieved in September 2009. 3D seismic surveys of the injection zone were completed in March 2010 in preparation for Phase 2.

Construction activities began at Decatur on August 26, 2011 with injection commencing in November 2011. As of April 2012, the project has successfully stored over 110,000 tons of CO2. In September 2012, the DOE marked 2 major milestones for the Decatur CCS project: The construction on the project’s storage facility, as well as the public opening of the National Sequestration Education Center. In November 2012 Decatur project completed its first year of CO2 injection operations with a total of 317,000 tons having been buried at a rate of 1,100 tons/day.

The target formation, the Mount Simon Sandstone, was selected as the optimum saline sink because of its widespread nature and immediately overlying Eau Claire shale seal. The Mount Simon Sandstone also underlies one of the largest concentrations of coal fired power plants in the world. This makes the Mount Simon Sandstone one of the most significant carbon storage resources in the United States.

Archer Daniels Midland (June 2010) was selected to receive an additional $99 million in federal aid for a second carbon sequestration project.

In May 2013 two monitoring wells in the the Mount Simon sandstone formation have been drilled, cemented and cased. The project is now waiting to receives the Class VI UIC permit in order to drill its injection well—and finish perforating its two monitoring wells. Construction of the surface facilities is expected to be completed in June 2013.
