Significant Geological Storage Capacity for Carbon in the United States, Report Finds



The United States has enough capacity to store a mean estimate of about 3000 metric gigatons (Gt) of carbon dioxide (CO2) through geological sequestration, according to a new assessment that looks at the potential for technically accessible geological CO2 storage in the country. That storage capacity is more than 500 times the nation's 2011 energy-related emissions, which the U.S. Energy Information Administration estimated at 5.5 Gt, and more than 90 times the 2011 global emissions of 31.6 Gt.
