DOE Outlines Its CO2 Estimate Methodology

October 2, 2008

The U.S. Department of Energy has detailed the methodology it uses to produce geologic resource estimates for its carbon dioxide sequestration program.

Officials this week released the Methodology for Development of Geologic Storage Estimates for Carbon Dioxide, which outlines the procedures used to estimate the nation’s storage potential in the soon-to-be-released 2008 Carbon Sequestration Atlas of the United States and Canada. The updated version of that award-winning atlas is to be released in November.

The methodology outlines the procedures for estimating CO2 storage potential in three types of geologic formations found in the United States and Canada: saline formations, unmineable coal seams and oil and gas reservoirs.

“This important document represents more than a year’s worth of work by researchers at the Office of Fossil Energy’s National Energy Technology Laboratory and members of (the department’s) regional carbon sequestration partnerships to reach a consensus on the methodology,” said Acting Assistant Secretary for Fossil Energy James Slutz. “We believe it will provide a sound explanation for geologic resource estimates in our upcoming carbon sequestration atlas.”

The methodology document is available in PDF format at http://fossil.energy.gov/programs/sequestration/publications/Project_Reports/carbonstorage_method08.pdf. It will also be presented as an appendix in the forthcoming Atlas II.
