This project’s objective is to explore the viability of a commercial-scale carbon capture storage (CCS) project in western Nebraska. Specifically, this project will (1) examine the challenges of commercial-scale CCS; (2) conduct high-level sub-basinal evaluations; and (3) perform a carbon dioxide (CO2) source assessment at Gerald Gentleman Station (Figure 1) and other CO2-emitting facilities. The anticipated outcome of this project is the collection of sufficient information that will ultimately justify advancing this project toward the demonstration of a commercial-scale CCS target capable of storing at least 50 million metric tons of CO2.
This project will further develop an established CCS team of both technical and nontechnical organizations and stakeholders that can help address challenges presented by a potential Nebraska CCS project. Additionally, this project will continue to examine various strategies to attain economic feasibility and public acceptance of a Nebraska CCS project. Finally, this project will perform a sub-basinal geologic assessment that will verify suitability for a commercial-scale CCS storage project, as well as the suitability of the identified CO2 sources. These benefits are in line with the U.S. Department of Energy’s (DOE) goals of validating technologies that will ensure 99 percent storage permanence and developing technologies that improve reservoir storage efficiency while ensuring containment effectiveness.
