Optimizing Alabama’s CO2 Storage in Shelby County (OASIS) – Final Report

Summary

The Optimizing Alabama’s CO2 Storage in Shelby County (OASIS) project addressed the challenge of a lack of economically viable geological CO2 storage options for industrial plants in Shelby County, Alabama, including the 1.88 GW Plant Gaston. The approach involved drilling and characterizing a deep stratigraphic test well to establish the foundation for a commercial-scale geologic CO2 storage complex. While the project is completed, the findings indicate limited storage opportunity under typical CCUS strategies, making the project currently uneconomic due to the high number of wells needed and capture costs; however, further exploration in the deep Cambrian Rome Formation could improve viability.
