Carbon Capture and Sequestration (CCS): A Primer [May 14, 2012]   [open pdf - 478KB]

"Carbon capture and sequestration (or storage)--known as CCS--is a physical process that involves capturing manmade carbon dioxide (CO2) at its source and storing it before its release to the atmosphere. CCS could reduce the amount of CO2 emitted to the atmosphere despite the continued use of fossil fuels. An integrated CCS system would include three main steps: (1) capturing CO2 and separating it from other gases; (2) purifying, compressing, and transporting the captured CO2 to the sequestration site; and (3) injecting the CO2 in subsurface geological reservoirs or storing it in the oceans. […] This report is a brief summary of what CCS is, how it is supposed to work, why it has gained the interest and support of some members of Congress, and what some of the challenges are to its implementation and deployment across the United States. Several other CRS [Congressional Research Service] reports cover different aspects of CCS in more detail, such as capture technology, challenges to siting and infrastructure, policy challenges to a comprehensive climate policy, and others. These are listed in the last section of this report, titled 'Other CRS Reports.' This report covers only CCS and not other types of carbon sequestration activities whereby CO2 is removed from the atmosphere and stored in vegetation or soils, such as forests and agricultural lands."
