Carbon dioxide capture and geological storage

Carbon dioxide capture and geological storage is a technology that could be used to
reduce carbon dioxide emissions to the atmosphere from large industrial installations
such as fossil fuel-fired power stations by 80–90%. It involves the capture of carbon
dioxide at a large industrial plant, its transport to a geological storage site and its longterm
isolation in a geological storage reservoir. The technology has aroused considerable
interest because it can help reduce emissions from fossil fuels which are likely to remain
the dominant source of primary energy for decades to come. The main issues for the
technology are cost and its implications for financing new or retrofitted plants, and the
security of underground storage.
