The United States Carbon Utilization and Storage Atlas contains four main sections: (1) Introduction; (2) National Perspectives; (3) Regional Perspectives (RCSPs); and (4) ARRA Site Characterization Projects. The Introduction section contains an overview of CCUS technologies, a summary of DOE’s Carbon Storage Program, a brief description of the RCSP Program, and information on the National Carbon Sequestration Database and Geographic Information System (NATCARB). The National Perspectives section contains maps showing the number, location, and magnitude of CO2 stationary sources in the United States, as well as the areal extent and estimated CO2 storage resource available in geologic formations evaluated within the RCSP regions. The Regional Perspectives section includes a detailed presentation of CO2 stationary sources, CO2 storage resource assessments, updates on field projects, and additional information key to each RCSP. Finally, the ARRA Site Characterization Projects section includes a detailed background of each project, its objectives, and a status update.
