Examining CCS Deployment Potential in China Via Application of an Integrated CCS Cost Curve

AbstractPreviously published cost curves focusing on CO2 transport and storage have helped illustrate the large potential for CCS technologies to deploy in China. This paper examines results from recent work to incorporate the costs of CO2 capture and compression into integrated cost curves that more fully reflect expected costs across the set of large, industrial CO2 sources and better illuminate the possible value of CCS to this fast-growing economy. Results show that significant potential exists for large-scale deployment of CCS at costs less than $70/tCO2. Mapping the cost curve results confirms that the majority of existing CO2 point sources may be able to utilize CCS technologies, and that except for many sources in southern China onshore storage capacity appears accessible and sufficient for decades of large-scale deployment
