This project is to study the pre-feasibility of an integrated CO₂ storage hub in the mid-continent region of the United States, with the ultimate objective of storing anthropogenic CO₂. As part of the Integrated CCS Pre-Feasibility phase of the Carbon Storage Assurance Facility Enterprise (CarbonSAFE) Initiative, Battelle Memorial Institute, in partnership with Archer Daniels Midland, Schlumberger Carbon Services, and the Geological Survey of the Nebraska Conservation and Survey Division, will develop a scenario complete with preliminary plans for implementation that address site-specific geologic, engineering, operational, legal, and regulatory aspects of the project. The study will develop preliminary economic estimates that will aid in planning future phases of the project, helping to develop the most efficient implementation schedule for a commercial-scale, integrated storage hub utilizing potential stacked storage reservoirs in Nebraska and Kansas (Figure 1). 

Tasks include identifying and reviewing major sources of CO₂, conducting a sub-basinal geologic stacked storage assessment, and determining the parameters for the proposed storage facility. Additionally, the testing of selected National Risk Assessment Partnership (NRAP) tools will be incorporated into several steps of the geological assessment. The project will work towards the DOE objective of producing a feasible carbon capture and storage (CCS) stacked storage complex in the mid-continent region.
