In this paper, a novel integrated solar and wind energy-based system for electricity and hydrogen generation is examined. This system consists of the photovoltaic, solar pond, wind turbine, organic Rankine cycle (ORC), PEM electrolyser, PEM fuel cell, hydrogen and oxygen storage subsystems. Thermodynamic analysis, environmental impact assessment and also parametric studies are analysed to research the impacts of various working parameters on the exergy destruction rates and exergy efficiencies of the integrated system parts and whole system. The energy and exergy efficiencies for the renewable-based integrated system are found to be 46.9% and 36.5% at reference temperature and pressure condition, respectively. In addition, the results of this paper indicate that the primary sources of irreversibilities in the integrated system are the solar pond system and ORC system. Finally, environmental impact assessments show that the emissions of CO2 in kg per kWh for power generation are lower for the wind turbine and PV systems.
