A two-year research study to assess the availability and costs of geologic CO2 storage for large anthropogenic CO2 point sources across North America has recently been completed. Employing a series of cost-minimizing decisions to pair 2,082 large CO2 point sources with their accessible least-cost CO2 storage option from among more than three hundred candidate geologic storage reservoirs, the study has, for the first time, developed a set of cost curves for CO2 transport and storage in North America. This work, prepared for and recently published by the IEA Greenhouse Gas R&D Programme (Building the Cost Curves for CO2 Storage: North America), documents the abundant storage capacity in North American deep saline formations, depleted oil and gas reservoirs, and unmineable coal seams, available at transport and storage costs that range from -$7 to $55 per tonne CO2. In this paper, the authors highlight the key findings from this research before building upon the results to provide a more detailed picture of the extent to which low-cost CO2 storage capacity is available in this region -- predominantly within value-added reservoirs in which CO2 injection results in enhanced hydrocarbon recovery. The implications that this storage resource may have for the short- to mid-term deployment of CCS within the United States and Canada are discussed.
