| Abstract: | The implementation of the geological sequestration and utilization of CO2 (CGSU) has considerable effects on CO2 emission reduction and is of great significance for the mitigation of global warming and the execution of the sustainable development strategy in China. Therefore, this study sorted the major methods for CGSU, made statistics of the global demonstration projects of CGSU, and primarily introduced the typical demonstration projects of CGSU in China. Furthermore, this study proposed prospects for the development trend of the CGSU technologies, which primarily include CO2 enhanced oil recovery (CO2-EOR), CO2 enhanced coalbed methane recovery (CO2-ECBM), CO2 enhanced saline water recovery (CO2-ESWR), CO2 enhanced nature gas recovery (CO2-ENGR), CO2 enhanced shale gas recovery (CO2-ESGR), CO2 enhanced geothermal power generation (CO2-EGP), and CO2-based in-situ leaching of uranium (CO2-ILU) at present. Among them, CO2-EOR, CO2-ESWR, and CO2-ILU have been widely and commercially applied at home and abroad due to their complete technical systems, while other methods of CGSU are still in the stage of field tests and engineering exploration. A total of 23 CGSU projects have been implemented in China, including 12 CO2-EOR projects, two CO2-ESWR projects, seven CO2-ECBM projects, and two CO2-ILU projects. The CGSU technology in China started late and still lags behind that of developed countries in Europe and the USA. There is an urgent need to accelerate the construction of demonstration projects of the whole process technology and cluster deployment of CGSU with a scale of more than 1 million tons/year and enhance the basic science research on the technology and cluster deployment of CGSU in the future. The main purpose is to solve the bottlenecks in the critical links of the whole-process technology of CGSU. |
