Abstract

The usage of multi-generation systems is quickly developing in recent years. The present study analyzes the energy, exergy, economic and environmental (4E) of a novel Rankine organic cycle to produce power, hydrogen and fresh water with a combined energy source of geothermal and heat recovery. Also, the cycle performance in both modes with and without geothermal energy is compared. Calculations show that the highest percent of exergy destruction is equal to 35% and is related to the PEM Also, the lowest amount of exergoeconomic factor is calculated for the PEM is equal to 8.39 The amount of hydrogen and desalinated water produced is 1.64 lit/s and 4.36 kg/s, respectively. With increasing the temperature of the geothermal source from 125 to 155°C, the amount of hydrogen and desalinated water produced are 29 and 17 percentage increases, respectively. If geothermal energy is not used and all energy is supplied by heat recovery, the amount of carbon dioxide emitted will increase to 69%.
