Abstract

There is growing concern about the release of pollutants from the use of fossil fuels. These concerns have led to the increased use of renewable energy sources and green energy carriers such as hydrogen. This paper evaluates a new hydrogen production system using a solar energy source. For this purpose, the concentrated photovoltaic (CPV) system is used for the first time as the driver of the proposed hydrogen production system. The first and second laws of thermodynamics and the conservation of mass and energy are used to simulate the system. The results show that the PV production power is 1529.4 kW, the turbine output power is 1015.3 kW, the pump consumption power is 126.5 kW, the hydrogen production is 6 grams per second, the energy efficiency is 8.84% and the exergy efficiency is 36.77%. On the other hand, the parametric analysis shows that increasing the nominal efficiency of the PV panel increases the PV power generation, in addition, increasing the ambient temperature decreases the PV power generation. Also, increasing the fluid quality at the evaporator outlet increases the energy efficiency and exergy.
