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 300 candidate geologic storage reservoirs, the authors have 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), is the culmination of a 2-year research effort to assess the availability and costs of CO2 storage for large anthropogenic CO2 point sources across the region. In this paper, the authors highlight the key findings from this research which documents 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. The authors then build upon this work to present a more detailed picture of the tens of gigatonnes of low cost CO2 storage capacity identified from the storage supply curve methodology, available predominantly within value-added reservoirs in which CO2 injection results in enhanced hydrocarbon recovery, along with a discussion of the significance that this capacity may have on short- to mid-term deployment of CCS within the United States and Canada.
