Carbon Capture and Storage - Technologies and Risk Management

Abstract

GHGs can be subdivided into two groups: those present in the atmosphere since before the industrial revolution and those that are chemical compounds created and produced by humans. The first group includes carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), whose concentrations in the atmosphere have been rising as a consequence of intensification of human activity. The second group includes perfluorocarbons (PFCs), chlorofluorocarbons (CFCs), hydrofluorcarbons (HFCs), hydrofluorchlorocarbons (HCFCs) and sulfur hexafluoride (SF6). Each of these gases has a different potential to absorb infrared radiation.
