A hybrid (solar-hydrogen) renewable energy system consisting of photovoltaic (PV) panels, proton exchange membrane (PEM) fuel cells, PEM-based electrolyzers, and hydrogen storage has been investigated for a stand-alone application, which was established for the emergency room of Kecioren Training and Research Hospital in Ankara, Turkey. A complete model of the hybrid renewable energy system has been developed using TRNSYS. The main goal of the study is to meet the electrical power demand of the emergency room without any shortage for a complete year in an emergency blackout condition. The emergency room has a peak electrical load of 5, kW and a yearly load of 37.23 MWh. The PV panels are mounted on a tiltable platform to improve the performance of the system. The total area of the PV panels is 300, m2, and the PEM fuel cell capacity is 5, kW. The hydrogen storage pressure is 55 bars with the capacity of 45, m3. Energy and exergy analysis is performed for the hydrogen cycle of the system for a complete year. Overall energy and exergy efficiencies of the hydrogen cycle of the system are calculated as 4.06% and 4.25%, respectively.
