Development of Techno-Economic Evaluation Model for CCS (Carbon Capture & Sequestration)

Abstract

In this study, Techno-economic evaluation model for carbon capture & sequestration (CCS) technologies are reviewed. Based on a key parameters of Korea’s electricity market, performance data of 10 ㎿-scale post-combustion CO₂ capture pilot plant in Boryong station, the cost of CO₂ avoided was evaluated followed by international guideline suggested by IEA CCS costing methods task force. The result showed that Korea’s Electricity cost including CAPEX & OPEX of reference power plant is relatively low compared to OECD nations which lead to a lower CCS cost (33 USD t/CO₂). And future work using newly evaluated CAPEX & OPEX data of power plant with/without CCS is recommended.
