이산화탄소 처리에 대한 발전원별 원가비교분석을 활용한 이산화탄소 해양지중저장기술의 경제적 효율성 평가

초록

This study attempts to analyze the economic efficiency of Carbon Dioxide Capture and Storage(CCS) by using the replacement cost approach, which compares the economic efficiency between CCS and other methods for CO2 reduction. The results show that the benefits of CO2 reduction in several power plants are similar among them, but the costs for the generation of electricity in them are quite different. In case of IGCC with CCS, the cost is 28.0 to 51.0 Korean won/MWh, which is second lowest, while the cost of a nuclear energy power plant is 10.3 Korean won/MWh. However, the costs for the generation of power can be different by the technology development, the social cost, and the real rate of operation of each plant.
