California-Nevada CO2 Storage Project

Electric Power Research Institute (Palo Alto, California) and the project participants intend to confirm the commercial storage capacity of a basalt storage complex and demonstrate the techno-economic feasibility of safely transporting and storing CO2 from the Tracy Power Station in Sparks, Nevada and other CO2 sources in the region to the onshore basalt storage complex on the Modoc Plateau in northeastern California. The CANstore Phase II project will involve geologic characterization activities, including drilling a stratigraphic well through approximately 1,700 meters of basalts, interbeds, and sediments into the basement; well logging, and hydrologic testing campaign; subsurface modeling studies to predict the size and shape of the subsurface CO2 footprint; and sensitivity analyses to validate simulation, characterization, and monitoring approaches necessary to support a successful UIC Class VI permit application. The outcomes of this project will remove barriers to carbon capture and storage development in northern California-Nevada and demonstrate mineralization storage in basalts at a scale that will help de-risk net-zero and net-negative development projects across the region.
