 Carbon Storage Atlas -  Fifth Edition (Atlas V) (2015)CARBON STORAGE ATLAS

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 Estimates of CO2 Stationary Source Emissions and Estimates of CO2 Storage Resources for Geologic Storage Sites
Atlas V Estimates of CO2 Stationary Source Emissions and Estimates of CO2 Storage Resources for Geologic Storage Sites

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).

The NATCARB Viewer provides flexible tools to access and display CCS. User can access the panel at right to interact with Viewer and query information.

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 CO2storage 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.



The NATCARB Viewer allows users to browse and query data under Regional Carbon Sequestration Partnership (RCSP), Atlas V, Worldwide CCS Database, Brine Well Samples, and other tabs.
CO2 Storage Formations
CO2 Storage Formations
The NATCARB Viewer displays the location of potential CO2 storage formations in different sedimentary basins throughout the United States and Canada. These formations include saline formations, oil and reservoirs, and unmineable coal areas. 
CO2 Stationary Sources
CO2 Stationary Sources
The NATCARB Viewer displays CO2 stationary source data obtained from the RCSPs and other external sources.

The NATCARB Viewer displays CO2 storage resource data that were obtained by the RCSPs and other sources and compiled by the NATCARB team. Carbon dioxide geologic storage information in the NATCARB Viewer was developed to provide a high-level overview of CO2 geologic storage potential across the United States and parts of Canada. Areal extents of geologic formations and CO2 resource estimates presented are intended to be used as an initial assessment of potential geologic storage. This information provides CCS project developers a starting point for further investigation. Furthermore, this information is required to indicate the extent to which CCS technologies can contribute to the reduction of CO2 emissions and is not intended to serve as a substitute for site-specific assessment and testing. Please note that data resulting in a straight edge in the map above is indicative of an area lacking sufficient data and is subject to future investigation. States/Provinces with a "zero" value represent estimates of minimal CO2 storage resource, while states/provinces with a blank represent areas that have not yet been assessed by the RCSPs.
