This study investigates an integrated energy system designed to supply 100% heat and power to a remote application, renewably. The system comprises a solar photovoltaic (PV) system with hydrogen-based energy storage (SH), a fuel cell heat recovery arrangement, an electric inline heater (powered by the PVs), and a solar thermal system (ST), altogether operating as a renewable combined heat and power solution. A theoretical simulation model is developed in MATLAB to conduct this study. The addition of the inline heater (powered by the PVs) resulted in improving the overall reliability of this integrated renewable energy arrangement from ∼95% to 100% with no additional costs. Additionally, the system is competitive against diesel generator (for power supply) and gas hot water system that is mostly used conventionally in remote areas.
