EU GeoCapacity (Assessing European Capacity for Geological Storage of Carbon Dioxide) is a 3-year project that ran from January 1st 2006 to December 31st 2008, and that was carried out by 26 partners in 21 countries including China, providing the first detailed pan-European assessment of CO₂ storage capacity. Other outcomes were the development of innovative methods for capacity assessment, economic modelling and site selection. An important mission was to initiate scientific collaboration, with China and other CSLF members (e.g. Russia). In China, the study was applied to the Hebei Province, which is located in the Bohai Basin, NE China. The inventory of emission sources was performed for the entire Hebei Province, while storage potential was studied in one of the major tectonic units of the basin, the Jizhong depression, in the south of the Province. The distribution of the main CO₂ emitters by sector has shown that besides the power sector, industry must be considered, in particular iron/steel and cement sectors accounting for one third of the total. Least cost transport was calculated using a methodology developed by 3E/INET (Tsinghua University) and BRGM (Chen et al., 2010) and applied also to the other CCS projects in China. The NZEC Conference, held in Beijing (28–20 October 2009) to close phase 1 and launch phase 2 of this European programme in China, concluded that storage is the most critical issue. At the present early stage, low-cost capture and transport should be preferred. Therefore, should incentives, performing investigation tools and adequate partnership be in place, several small-scale demonstration projects from local industry to local storage sites are recommended to improve knowledge and operating conditions prior to any ambitious project. CCS deployment in the Hebei province could be performed from local sources to local sinks of CO₂. However, EOR is limited by the present water cut or reservoir geometry and geothermal reconversion might be profitable. Tertiary aquifers would be a good target, but the Neogene (Guantao, Minghuazhen formations) seems restricted to other uses (geothermal, water supply). Therefore, more coordination between geothermal exploration and CCS, and new objectives in the deeper Tertiary (Paleogene) would be suitable for CCS deployment.
