This research proposes a novel geothermal-concentrated photovoltaic/thermal (CPV/T)-based multi-production energy system undertaking to deliver power, dried date, cooling load andhydrogen. The desired system contains an organic Rankine cycle (ORC), magnetic refrigerator and proton exchange membrane (PEM) electrolyzer as the substantial subsystems. Energy and exergy analyses are applied to simulate the desired system and the key parameters, namely PEM electrolyzer mass flow rate ( 9 m ), geothermal water mass flow rate ( 1 m ), geothermal watertemperature ( 1 T ), inlet pressure of ORC turbine ( 5 P ), PEM electrolyzer water temperature ( 10 T ), and current density ( J ) are evaluated on the annual energy and exergy efficiencies of theproposed system. Parametric study indicate that 9 m , 5 P and 10 T have a positive effect on both thermal and exergy efficiencies sothat these variables improve the thermal efficiency within 24%, 38% and 20% , respec
