Financial Assessment of CO2 Capture and Storage with Electricity Trading in the U.S.: Role of Interim Storage and Enhanced Oil Recovery

摘要

This paper investigates the economic attractiveness of exporting coal-generated electricity from the State of Wyoming to the State of California while investing in large-scale CO2 capture and sequestration to meet California's strict environmental regulations. The project involves partially capturing CO2 from coal power plants, storing it temporarily underground using CO2 Interim Storage, and ultimately using it for Enhanced Oil Recovery. A detailed financial assessment is performed in view of current electricity prices and federal and state regulations in the U.S., especially those related to CCS tax credits. The results show that the project is profitable under current regulations and technical assumptions, and it can be a good opportunity to drive large-scale deployment of CCS, along with the development of EOR activities and the deployment of the newly proposed CO2 Interim Storage technology.
