Costs and Performance of Advanced Zero Emission Systems of IGCC with CCS in Japan

AbstractThis paper provides processes and results of economic evaluation of advanced zero emission systems of Integrated Gasification of Combined Cycle (IGCC) with Carbon Capture, transport and Storage (CCS). The project named FS was funded by New Energy and Industrial Technology Development Organization (NEDO). The IGCC+CCS system has following three characteristics. (1) Net output is 300 MWe, relatively small in comparison to other commercialized pulverized coal combustion power plants. (2) Assessment of transportation and storage is rich in technologies as well as site-specific characteristics for various transportation patterns using ships and pipelines (PL) between sources and sinks. And (3) The system is designed for a post- demonstration plant in the brown field expected to be constructed in the beginning of 2020s, hence as a result, its economic evaluation should be considered as “first of a kind” (FOAK). Six transportation cases were investigated, as the majority of the plants are located along the coast of Japan. Cost evaluation for storage was based on the preceding studies in Japan where an emphasis was placed on IGCC with detailed designed CCS systems, including varieties of recovered CO2 transportation
