In the 2013 national assessment of geologic carbon sequestration, USGS looked at every sedimentary rock basin in the country. Then, using a series of criteria developed in an internationally-recognize...
d, peer-reviewed methodology, USGS scientists narrowed the list of basins to assess to 36 total.
What qualified these 36 basins? First, the deep prospective storage zones did not have fresh sources of groundwater. The U.S. Environmental Protection Agency defines groundwater as being fresh if it has 10,000 milligrams per liter of dissolved material or less.
Next, the rock had to be deep enough to ensure that the CO2 remained a liquid. That limited the available formations to those deeper than 3,000 feet. The majority of the rock layers chosen were between 3,000 and 13,000 feet, but some were deeper.
Last but certainly not least, the storage rock layers had to have a sealing layer on them that would prevent the CO2 from escaping.
