A REVIEW OF CO2 STORAGE TECHNOLOGY AND PERSPECTIVE OF CO2 STORAGE IN THE NEARSHORE AREA OF SOUTH CHINA
-
摘要: 我国大多南方沿海经济发达地区的CO2减排压力大。CCS是继续利用化石能源的同时实现CO2近零排放的惟一有效技术,CO2地质封存是其关键环节。我国南方近海发育一些大型盆地,沉积地层厚度大,储盖层组合好,圈闭非常发育,具有CO2封存的有利地质条件。海域封存具有不需征地、安全性高、环境影响小等优点,具有广阔的发展前景。而大多南方沿海省份陆上缺乏大型沉积盆地,在近海封存是惟一的选择。因此,应该在我国南方近海建设CO2封存示范工程。Abstract: 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.
