CO2 capture, utilization and storage(CCUS) shows very a charming development prospect in China. CO2 geological storage combined with deep saline water recovery (CO2-EWR), as a new CCUS technology which not only achieves deep emission reduction, but also alleviates the water shortage situation, is no doubt a win-win choice ensuring national energy security for China's energy structure with coal. China mainland can be partitioned into three potential CO2-EWR zones mainly according to the different types of aquifer system. Considering Research and Development(R & D) maturity and cost prediction of the technology, coal power and coal chemical enterprises in the western region has an early opportunity, so analysis and evaluation mainly focus on coal chemical industry in the western China (Zone One) in this study. CO2-EWR technical elements in the full chain technology are discussed on the basis of outline of CO2-EWR concept, significance and overview of latest research, and finally CO2-EWR technology development and important implementation direction are pointed out.
