Mt. Simon Sandstone
Clean Coal Power Initiative, US
Archer Daniels Midland Company (ADM), the Midwest Geological Sequestration Consortium (MGSC) and the Illinois State Geological Survey (ISGS) are working together on this carbon sequestration project. The project will involve the capture and storage of carbon dioxide from ADM’s ethanol plant in Decatur, Illinois.
Mount Simon Sandstone, is a major regional saline-water-bearing rock formation in Illinois, where 1 million tons of carbon dioxide over a period of three years will be stored. The carbon dioxide will be provided by ADM from its Decatur, Illinois, ethanol plant, and the project will be located on ADM’s Decatur property.
In this project, wells will be drilled into the Mount Simon Sandstone at an expected depth of more than 6,500 feet. Carbon dioxide from ADM’s ethanol plant will be injected into the Mount Simon Sandstone, where the compressed liquid-like carbon dioxide will be stored in the porous saline rock formation. The safety and effectiveness of the storage will be monitored by the MGSC through an extensive monitoring, mitigation and verification program.
The $84.3 million project will be funded by $66.7 million from the U.S. Department of Energy over a period of seven years, supplemented by cofunding from ADM and other corporate and state resources.
The project began in spring 2008 with the drilling of the injection well. Environmental monitoring began in October 2008 and collected a year of background information. The sequestration and injection of carbon dioxide was scheduled to began October 2009 and end in 2012.
About the Midwest Geological Sequestration Consortium
The Midwest Geological Sequestration Consortium (MGSC) is one of seven regional partnerships selected by the U.S. Department of Energy to determine the best approaches for capturing and storing carbon dioxide (CO2) that might otherwise contribute to global climate change. The MGSC is led by the Illinois State Geological Survey, in conjunction with the Indiana Geological Survey and the Kentucky Geological Survey, and covers Illinois, southwestern Indiana and western Kentucky. This partnership was estab¬lished to assess geological carbon se¬questration options in the 60,000 mi2oval-shaped, geologic feature known as the Illinois Basin. Within the Basin are deep, noneconomic coal resources, numerous mature oil fields and deep saline rock formations with potential to store CO2. MGSC’s objective is to determine the technical and economic feasibility of using these geologic formations for long-term storage.
About the Illinois State Geological Survey
Founded in 1905, the Illinois State Geological Survey provides the citizens and institutions of Illinois with earth science research and information that are accurate, objective and relevant to the state’s environmental quality, economic prosperity and public safety. ISGS is one of four scientific surveys affiliated with the University of Illinois and headquartered on its campus in Urbana-Champaign. Together they form a unique group of scientific experts in the earth, environmental and biological sciences that is unmatched in the nation. These agencies carry out objective, high-quality, multi-disciplinary scientific studies in service to all the people of Illinois.
