There are important differences in the operation of power plants in China that affect the performance and economics of post-combustion CO2 capture systems relative to other parts of the world. These include the possibility of lower capture rate requirements, salient differences in the installed power plant infrastructure, and flexible operation in the forms of reduced capacity factors and load-following. This paper quantifies these China-specific conditions that CO2 capture technologies will encounter at coal-fired power plants in China and proposes a suite of idealized test challenges that can be used to supplement testing of candidate technologies during the pilot stage. Data from these challenges can be used to improve accuracy in estimates of operational performance, robustness, and economic potential and also provide early insight into technology development needs.
