Carbon capture and storage (CCS) is a technique to remove carbon dioxide from industrial pollution - and especially from power stations - and compress, transport and store it perpetually in secure underground structures such as expired gas and oil fields and other geological formations. 

CCS is experimental, unproven technology at the scale required, and if it works the majority of CCS deployment will not occur until the second half of this century, according to the 2005 Intergovernmental Panel on Climate Change special report on carbon dioxide capture and storage.
