International interest in CO₂ capture and storage (CCS), as a method of reducing carbon dioxide emissions linked to global climate change, has been growing in recent years. CCS is particularly attractive for large industrial facilities, especially electric power plants, which contribute a large share of global CO₂ emissions from combustion of coal and other fossil fuels. This paper describes the current status of technologies to capture CO₂ and transport it to a storage site. The performance and cost of capture technologies are discussed, along with related environmental issues and the outlook for improved, lower-cost strategies. The key need now is financing of full-scale demonstrations of CCS at the various types of large coal-based power plants.

KEYWORDS: CO₂ capture, CO₂ transport, carbon sequestration costs, postcombustion capture, precombustion capture, oxycombustion capture
