Abstract

In 2008, the top CO2emitters were China, United States, and European Union. The rapid growing economy and the heavy reliance on coal in China give rise to the continued growth of CO2emission, deterioration of anthropogenic climate change, and urgent need of new technologies. Carbon Capture and sequestration is one of the effective ways to provide reduction of CO2emission and mitigation of pollution. Coal-fired power plants are the focus of CO2source supply due to their excessive emission and the energy structure in China. And over 80% of the large CO2sources are located nearby storage reservoirs. In China, the CO2storage potential capacity is of about 3.6 × 109 t for all onshore oilfields; 30.483 × 109 t for major gas fields between 900 m and 3500 m of depth; 143.505 × 109 t for saline aquifers; and 142.67 × 109 t for coal beds. On the other hand, planation, soil carbon sequestration, and CH4–CO2reforming also contribute a lot to carbon sequestration. This paper illustrates some main situations about CO2sequestration applications in China with the demonstration of several projects regarding different ways of storage. It is concluded that China possesses immense potential and promising future of CO2sequestration.
