Carbon capture and sequestration (CCS) has long been touted as a potentially critical means for reducing greenhouse gas emissions from carbon-intense industrial sources. High costs, complex regulatory schemes, and decreasing governmental incentives, however, have hindered the widespread development of CCS projects. But a growing trend of deriving multiple revenue streams from the carbon dioxide (CO2) associated with CCS projects—particularly using captured CO2 for enhanced oil recovery—is helping to spur CCS development.
