A recovery of high-quality by-product heat from a solid oxide fuel cell (SOFC) for steam production appears to be an interesting alternative to improve the SOFC performance. The produced steam can be used for chilled water generation via an absorption chiller. However, the main challenge in designing this combined cycle is the proper use of the SOFC exhaust gas in order to optimize the chilled water generation. Exergy analysis plays an important role in developing strategies and in providing guidelines for more effective use of exhaust heat in existing systems. In this study, a combined analysis of exergy and environmental impact (through greenhouse gas emissions) of the chilled water production process using the SOFC exhaust heat are performed under exergoenvironmental analysis. The study determines energy and exergy efficiencies, exergy destructions and CO2 emissions as well as sustainability indexes (SI).
