Carbon capture and storage (CCS) is being touted as a promising method of reducing carbon dioxide emissions into the atmosphere.The oil industry for decades has injected CO2 underground in enhanced oil recovery projects, so some science and technology exists for CCS, although many questions remain regarding both sequestration and climate change. Researchers have yet to demonstrate that CCS can be accomplished on a grand-enough scale to stabilize CO2 concentration levels.CCS envisions capturing CO2 from power plants, petrochemical plants, and other industrial users and sequestering it underground into depleted oil and gas fields, saline aquifers, and unmineable coal seams.The commercializa...
