초초임계압 발전소 확대에 따른 CO2 감축잠재량 연구

Abstract

In this study, the CO₂ emission factors of supercritical and ultra-supercritical power plants considering the transmission stage efficiency were calculated. The CO₂ reduction potential was calculated for the ultra-supercritical power plant, which was introduced up to 40%. The CO₂ emission factor of the supercritical power plant was 1.017 kg CO₂/kWh, while the emission factor of the ultra-supercritical power plant was 0.947 kg CO₂/kWh. Thus, the emission factor of the ultra-supercritical power plant was estimated to be about 7% lower. By calculating the CO₂ emissions according to the supercritical and ultra-supercritical power generation ratio, we found that when the power generation ratio of the ultra-supercritical power generation increased to 40%, the CO₂ emissions decreased by 1.74% (4,906,117 tons of CO₂).
