A pinch-based approach has been used to calculate optimum values of CO2 capture and storage (CCS) retrofit and compensatory renewable power for the Korean electricity sector. Three cases are proposed. In the first case, KEPCO 2020 power generation forecast data were used to calculate CO2 emissions and a 30% emission reduction target applied. For the second case, nuclear-free KEPCO 2020 forecast was used to calculate emissions along with 30% emissions reduction. In the third case, the emissions reduction target increased from 30% to 54.50% for case-2 scenario, in order to achieve 2005 emissions level. Results show that CCS retrofit and compensatory renewable power for case 3 is 2.6 times higher than case 1 and 1.8 times higher than case 2. According to sensitivity analysis results, CCS retrofit and compensatory renewable power for case 3 is more sensitive to CO2 removal ratio and parasitic energy loss ratio, respectively, as compared to case 1 and case 2.
