CO₂ capture and storage

Abstract

Carbon dioxide capture and geological storage are not new technologies: CO 2 capture and separation has been used in industry for decades, and CO 2 injection has been used since the 1970s for enhanced oil recovery. However, a number of obstacles still need to be overcome before they can be deployed on a large scale. This article reviews existing technologies, both mature and under development, and discusses the issues to be addressed: reducing the cost and energy penalty for CO 2 capture, pooling infrastructures for transport, demonstrating the feasibility of mass storage, and the outlook for use.
