Abstract: In the present study, a novel multi-generation system producing electricity, heating, cooling, thermal energy storage and hydrogen is investigated according to the thermodynamic and environmental point of views. The purpose of the present work is to thermodynamically examine and evaluate the performance of solar-aided multi-generation system. Different operating parameters are varied to assess the performance of the integrated multigenerational system. The results of the study illustrate that overall energy and exergy efficiency of the proposed integrated system is 51.62% and 53.45% respectively, while hydrogen production rate is observed to be 0.00742 kg/s.

Keywords: heliostat; multi-generation; overall energy; exergo-environmental; exergy; hydrogen.
