One Earth CCS

The One Earth CCS Project, developed by One Earth Sequestration, LLC, will capture CO₂ from the One Earth Energy ethanol plant in Gibson City, Illinois, which produces about 460,000 metric tons of CO₂ per year from fermentation. Captured CO₂ will be compressed, transported roughly five miles west by pipeline, and injected into the Mt. Simon Sandstone, with the Eau Claire Formation serving as the primary confining layer. The project is designed with three injection wells (OES #1, #2, #3), each capable of storing about 30 million metric tons of CO₂ over a 20+ year period, for a total storage capacity of ~90 million metric tons. A characterization well (OEE #1) was drilled in 2022 under the DOE’s CarbonSAFE Phase III Illinois Storage Corridor Project, providing site-specific data and confirming favorable geology. This well will later be converted to an in-zone monitoring well. Additional monitoring infrastructure will include wells in the St. Peter Sandstone (lowermost USDW) and Ironton-Galesville Sandstone, plus continuous geophysical, seismic, and groundwater monitoring to ensure containment.
