The primary purpose of the U.S. Department of Energy (DOE) Carbon Storage Atlas is to provide a coordinated update of carbon capture and storage (CCS) potential across the United States and other portions of North America. DOE has released five versions of the atlas with the most recent, “DOE’s Carbon Storage Atlas – Fifth Edition (Atlas V),” made publicly available in August 2015.
Atlas V contains updates to the carbon dioxide (CO2) storage potential for the United States and updated information on DOE’s carbon storage activities and field projects. These field projects include the large-scale field projects conducted by the Regional Carbon Sequestration Partnerships (RCSPs), small-scale field projects, and American Recovery and Reinvestment Act (ARRA) site characterization projects. In addition, Atlas V outlines DOE’s Carbon Storage Program, DOE’s CCS collaborations, worldwide CCS projects, and CCS regulatory issues; presents updated information on the location of CO2 stationary source emissions and the locations and storage potential of various geologic storage sites; and provides information about CCS commercialization opportunities.
Atlas V includes current and best available estimates of potential CO2 storage resource determined by a methodology applied across all of the regions. A CO2 storage resource estimate is defined as the fraction of pore volume of porous and permeable sedimentary rocks available for CO2 storage and accessible to injected CO2 via drilled and completed wellbores. Carbon dioxide storage resource estimates were derived from data collected by DOE field projects. This data is representative of each field project region and required estimation of parameters, such as area (A), thickness (h), and porosity (?), for each candidate storage formation.
National Carbon Sequestration Database and Interactive Viewer
The number of stationary CO2 sources, CO2 emissions, and CO2 storage resource estimates reported in Atlas V is based on information gathered by the National Carbon Sequestration Database and Geographic Information System (NATCARB). NATCARB is a relational database and geographic information system (GIS) that integrates CCS data from the RCSPs and other sources. NATCARB provides a national view of the carbon storage potential; data from NATCARB is uploaded into Energy Data eXchange (EDX).
NATCARB provides access to disparate datasets required for CCS deployment. It organizes and enhances the critical information about CO2 stationary sources, and develops the technology needed to access, query and model, analyze, display, and disseminate CO2 storage resource data. Data are generated, maintained and enhanced at each RCSP, or the publicly available data warehouses.
The NATCARB interactive viewer addresses broad needs of all users and provides easy data access on different platforms ranging from Desktops to mobile platforms like tablets. General public can access viewer and query database for wide variety of information on different CCS projects ranging from emission and storage potential to brine data for geochemistry.
