KEPCO-China Huaneng Post-combustion CO 2 Capture Pilot Test and Cost Evaluation

The proprietary post-combustion CO 2 solvent (KoSol) developed by the Korea Electric Power Research Institute (KEPRI) was applied at the Shanghai Shidongkou CO 2 Capture Pilot Plant (China Huaneng CERI, capacity: 120,000 ton CO 2 /yr) of the China Huaneng Group (CHNG) for performance evaluation. The key results of the pilot test and data on the South Korean/Chinese electric power market were used to calculate the predicted cost of CO 2 avoided upon deployment of CO 2 capture technology in commercial-scale coal-fired power plants. Sensitivity analysis was performed for the key factors. It is estimated that, in the case of South Korea, the calculated cost of CO 2 avoided for an 960 MW ultra-supercritical (USC) coal-fired power plant is approximately 35~44 USD/tCO 2 (excluding CO 2 transportation and storage costs). Conversely, applying the same technology to a 1,000 MW USC coal-fired power plant in Shanghai, China, results in a slightly lower cost (32~42 USD/tCO 2 ). This study confirms the importance of international cooperation that takes into consideration the geographical locations and the performance of CO 2 capture technology for the involved countries in the process of advancing the economic efficiency of large-scale CCS technology aimed to reduce greenhouse gases.
