Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding.
Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide.
Geologic carbon sequestration is the process of storing carbon dioxide (CO2) in underground geologic formations.
Atmospheric carbon dioxide comes from two primary sources—natural and human activities. Natural sources of carbon dioxide include most animals, which exhale CO2 as a waste product.
In 2013, USGS released the first-ever comprehensive, nation-wide assessment of geologic carbon sequestration, which estimates a mean storage potential of 3,000 metric gigatons of carbon dioxide.
All of the sedimentary rock basins for the entire country, including onshore and state waters, were evaluated based on criteria in the geologic carbon sequestration assessment methodology.
The minimum requirements for inclusion in the assessment included the following:
It is difficult to characterize one area as “the best,” because the answer depends on the question – best for what? However, the area of the assessment with the most storage potential for carbon dioxide is the Coastal Plains region, which accounts fo
In the 2013 assessment, USGS did not look at the economics of geologic carbon sequestration. What was assessed in this study was the technically accessible carbon dioxide storage potential, meaning it could be performed using today’s technology and st
