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.
This project will locate potential sites for a CCS facility in Nebraska and Kansas, specifically in proximity to several major carbon sources, and will further the understanding of reservoir types in the region that are conducive to carbon storage. This project will support the DOE’s Carbon Storage Program goals to develop technologies to ensure 99 percent storage permanence, with the ability to predict storage capacity to within ±30 percent. The Mid-Continent effort will also support the Carbon Storage Program mission to develop and advance CCS technologies for widespread commercial deployment in the 2025-2035 timeframe that will ensure safe, secure, efficient, and cost-effective CO2 containment in diverse geologic formations.
