摘要：Based on the operating data of a 40 tCOsub2/sub/day (2 megawatt (MW)) class carbon capture and utilization (CCU) pilot plant, the scaled-up 400 tCOsub2/sub/day (20 MW) class CCU plant at 500 MW power plant was economically analyzed by applying the levelized cost of energy analysis (LCOE) and COsub2/sub avoided cost. This study shows that the LCOE and COsub2/sub avoided cost for 400 tCOsub2/sub/day class CCU plant of mineral carbonation technology were 26 USD/MWh and 64 USD/tCOsub2/sub, representing low LCOE and COsub2/sub avoided cost, compared to other carbon capture and storage CCS and CCU plants. Based on the results of this study, the LCOE and COsub2/sub avoided cost may become lower by the economy of scale, even if the COsub2/sub treatment capacity of the CCU plant could be extended as much as for similar businesses. Therefore, the CCU technology by mineral carbonation has an economic advantage in energy penalty, power plant construction, and operating cost over other CCS and CCU with other technology.
