Carbon Dioxide Capture and Storage: An Overview With Emphasis on Capture and Storage in Deep Geological Formations

A transition to a low-carbon economy can be facilitated by CO ₂ capture and storage. This paper begins with an overview of CO ₂ capture and storage in the terrestrial biosphere, oceans, and deep geologic systems. The remainder focuses on what now appears to be the most promising option for large-scale deployment-capture and storage in deep geologic formations. A detailed description of the technology is provided, including the potential scale of application, cost, risk assessment, and emerging research issues
