Abstract

This paper presents the results of the cost of energy COE analysis of an integrated gasification combined cycle IGCC power plant with respect to CO2 capture ratio under the climate change scenarios To obtain process data for a COE analysis simulation models of IGCC power plants and an IGCC with carbon capture and sequestration CCS power plant developed by the United States Department of Energy DOE and National Energy Technology Laboratory NETL have been adopted and simulated using Aspen Plus The concept of 20year levelized cost of energy LCOE and the climate change scenarios suggested by International Energy Agency IEA are also adopted to compare the COE of IGCC power plants with respect to CO2 capture ratio more realistically Since previous studies did not consider fuel price and CO2 price changes the reliability of previous results of LCOE is not good enough to be accepted for an economic comparison of IGCC power plants with respect to CO2 capture ratio In this study LCOEs which consider price changes of fuel and CO2 with respect to the climate change scenarios are proposed in order to increase the reliability of an economic comparison And the results of proposed LCOEs of an IGCC without CCS power plant and IGCC with CCS 30 50 70 and 90 capturemole basis of CO2 in syngas stream power plants are presented
