Abstract

The polygeneration system based on H2-fueled solid oxide fuel cell (SOFC) is a high-efficiency and zero-carbon technology, but the exhaust gas it emits has a high temperature. In order to further improve the performance of the polygeneration system, based on the principle of energy cascade utilization, this study uses an H2-fueled SOFC as the driving force, and gas turbine (GT), supercritical CO2 (SCO2) cycle, organic Rankine cycle (ORC), and steam turbine (ST) cycle to recover the waste heat to achieve the high efficiency of electrical and heat supply. The proposed scheme which not only improves the efficiency of the system, but also reduces pollutant emissions. A physical model of the proposed system is constructed based on EBSILON Professional software and the performance of this polygeneration system is evaluated with energy analysis, exergy analysis and economic analyses. The results showed that the overall efficiency of the polygeneration system can reach 79.30 %, which is 11.45 % higher than the single SOFC/GT unit, and the exergy efficiency is up to 76.87 %. The dynamic payback period of the proposed design is 3.79 years, and the net present value is 73,757.29 thousand dollars, which has some advantages over the existing literature. Additionally, the impact of changes in some key system parameters on system performance was analyzed. The research findings of this project provide a new solution for the efficient operation of SOFCs.
