The CO2 will be stored permanently in the Mt. Simon Sandstone more than a mile beneath the Illinois surface at Decatur.

The CO2 is being captured from the fermentation process used to produce ethanol at Archer Daniels Midland’s corn processing complex.

It is compressed into a dense-liquid to facilitate the injection process and permanent storage at a depth of 7,000ft.

The demonstration project is part of the development phase of the Regional Carbon Sequestration Partnerships program which was launched in 2003 as a DOE Office of Fossil Energy initiative.

The aim of the project is to determine the best approaches for capturing and permanently storing greenhouse gases that can contribute to global climate change.

The MGSC is led by the Illinois State Geological Survey, part of the Prairie Research Institute at the University of Illinois.
