A REVIEW OF CO₂ STORAGE TECHNOLOGY AND PERSPECTIVE OF CO₂ STORAGE IN THE NEARSHORE AREA OF SOUTH CHINA

To reduce CO₂ emission has become an urgent mission of the better developed coastal provinces in south China. CCS is the only technology that makes the CO₂ emission approaching zero whereas fossil energy sources continue to be used. CO₂ geological storage is the key to CCS. In the offshore area of South China, there occur large-scale basins with thick sediments. The good combination of reservoir and seal rocks, and traps are available. It means that geological conditions are favorable for CO₂ storage. The geological storage of CO₂ has great advantages. It is safe for people, clean for environment, and there is no land requisition. It is the only choice to store CO₂ in offshore basins since there is no large-scale basin on land in most of the coastal provinces in south China. Demonstration projects for CO₂ geological storage are recommended in the offshore areas.
