Carbon Storage Atlas - Fifth Edition (Atlas V) (2015)

Atlas V Complete Document [PDF-55.3MB]

The U.S. Department of Energy’s (DOE) National Energy Technology Laboratory (NETL) is proud to release the fifth edition of the Carbon Storage Atlas (Atlas V). Production of Atlas V is the result of collaboration among carbon storage experts from local, State, and Federal agencies, as well as industry and academia. Atlas V provides a coordinated update of carbon capture and storage (CCS) potential across the United States and other portions of North America. The primary purpose of Atlas V is to update the carbon dioxide (CO2) storage potential for the United States and to provide updated information on DOE’s carbon storage activities and field projects.

The Carbon Storage Atlas contains the following sections: (1) Introduction to CCS; (2) DOE’s Carbon Storage Activities; (3) National Perspectives; (4) Large-Scale Field Projects; (5) Small-Scale Field Projects; and (6) American Recovery and Reinvestment Act (ARRA) Site Characterization Projects. The Introduction to CCS section is an overview of CCS. The DOE’s Carbon Storage Activities section includes a summary of DOE’s CCS activities, including information on DOE’s Carbon Capture and Storage Programs, NETL’s Research & Innovation Center, systems analysis activities, DOE interagency and global collaborations, and knowledge sharing efforts. 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 DOE-evaluated geologic formations. The Large-Scale Field Projects, Small-Scale Field Projects, and Site Characterization Projects sections include a detailed background of each project, its objectives, a status update, and additional information.

Atlas V includes current and best available estimates of potential CO2 storage resource determined by a methodology applied across all 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 assessments do not include economic or regulatory constraints; only physical constraints are applied to define the accessible part of the subsurface. Economic and regulatory constraints are included in geologic CO2 capacity estimates.

The number of stationary CO2 sources and CO2 emissions reported in Atlas V is based on information gathered by the National Carbon Sequestration Database and Geographic Information System (NATCARB) as of November 2014. Likewise, the CO2 storage resource estimates reported in Atlas V are based on information gathered by NATCARB as of November 2014. NATCARB is updated as new data are acquired and methodologies for CO2 storage estimates improve. Furthermore, it is expected that, through the ongoing work of DOE/NETL, data quality and conceptual understanding of the CCS process will improve, resulting in more refined CO2 storage resource estimates.
