Energy and Exergy Analyses of an Integrated System for Utilization of Excess Power from Thermal Power Plant

In this paper, we propose an integrated electrolyzer, proton exchange membrane fuel cell (PEMFC), and quadruple effect absorption refrigeration system (QEAS) for power and rate of cooling production from excess power produced by power plant. Some parametric studies are undertaken and the effects of some operating parameters such as excess power, current density and condenser load are investigated. It is found that increase in excess power results in higher power output but lower rate of cooling production. It is also found that increasing excess power decreases the overall energetic and exergetic utilization factors of the system.
