From 2010 to 2012, the China Geological Survey Center for Hydrogeology and Environmental Geology Survey (CHEGS) carried out the project “Potential evaluation and demonstration project of CO 2 Geological Storage in China”. During this project, we developed an evaluation index system and technical methods for the potential and suitability of CO 2 geological storage based on China's geological conditions, and evaluated the potential and suitability of the primary basins for CO 2 geological storage, in order to draw a series of regional scale maps (at a scale of 1:5) and develop an atlas of the main sedimentary basins in China. By using these tools, we delineated many potential targets for CO 2 storage. We also built techniques and methods for site selection and the exploration and assessment of CO 2 geological storage in deep saline aquifers. Furthermore, through cooperation with the China Shenhua Coal to Liquid and Chemical Co., Ltd., we successfully constructed the first coal‐based demonstration project for CO 2 geological storage in deep saline aquifers in the Yijinhuoluo Banner of Ordos in the Inner Mongolia Autonomous Region, which brought about the basic preliminary theories, techniques, and methods of geological CO 2 storage in deep saline aquifers under China's geological conditions.
