Lateline: Carbon capture and storage

Is carbon capture and storage (CCS) the solution to climate change? CCS technology captures carbon dioxide from the flue gases of coal burning power plants and takes it to long-term storage. The coal industry has high hopes that pumping the liquefied gas into underground reservoirs, or geo-sequestration, will provide safe ...
