deployed in coming decades in response to major climate and economic drivers: CCS is a central part of every major climate policy that limits global warming to 2°C or less, and is eligible for significant CO2 tax credits in the United States. These drivers are likely to stimulate capture, transport, and storage of hundreds of millions or billions of tonnes of CO2 annually. A key part of the CCS puzzle will be identifying and characterizing suitable site-scale geologic storage sites for vast amounts of CO2 (Figure 1). We recently developed a new approach to rapidly characterize the physical and economic performance of geologic storage reservoirs using a fast-running, open-source tool called SCO2T (Sequestration of CO2 Tool, pronounced “Scott”). SCO2T can rapidly screen hundreds of thousands of reservoirs, perform sensitivity and uncertainty analyses, and link sequestration engineering (injection rates, reservoir capacities, plume dimensions) to sequestration economics (total costs derived from more than 70 separate economic inputs). SCO2T has been further developed and commercialized by CARBON SOLUTIONS LLC (CARBON SOLUTIONS) to include new and advanced features such as supply-curve generation, dynamic injection and storage over multiple time periods, and monitoring and post-injection site care (PISC) costs. The new software is called SCO2TPRO.
