Dataset of CO2 geological storage potential and injection rate capacity in China based on fine grid technology
Carbon capture, utilization, and storage (CCUS) is a vital technology for mitigating climate change. However, the successful deployment of CCUS technology depends on a thorough understanding of subsurface CO<sub>2</sub> geological storage capacities and their spatial distribution. Currently, there is limited publicly available information on the CO<sub>2</sub> geological storage potential and injection rate capacity, particularly regarding fine-resolution gridded datasets for large countries with complex geological conditions like China. This study estimates China's onshore and offshore CO<sub>2</sub> geological storage potential and injection rate capacity with a fine resolution of 5 km covering 24 major sedimentary basins and 1181 oilfields. Using ArcGIS along with statistical tools, we produce five datasets at the grid level, four at the county level, and four at the provincial level. The reliability of this gridded dataset has been validated by literature comparisons and uncertainty analysis. These datasets are crucial for the optimal selection of carbon dioxide geological sequestration sites as well as for future CCUS strategic planning and large-scale deployment at various spatial scales.
