Optimal Design of Photovoltaic/Wind Turbine Systems for Producing Hydrogen Using a PEM Electrolyzer and MPPT Controller

The current trend is to use renewable energy such as solar energy and wind energy to produce hydrogen. It is necessary for us to make a comparison of the effect of each of these sources on hydrogen production, and which one is more efficient in different environmental variables. This paper studied and modeled two sources of renewable energy which are Photovoltaic (PV) and Wind Turbine (WT) to power Polymer Electrolyte Membrane Electrolyzer (PEMEL). By using MATLAB software, it is measured the input, and output power of PV and WT, the efficiency of the MPPT controller, and calculated the green hydrogen production rate and efficiency of each system separately. It is analyzed under variable irradiance from 600 to 1000 W/m 2 for a PV system and fixed temperature equal to 25°C. While under variable wind speed from 10 to 14 m/s and zero fixed pitch angle for WT system. The results obtained that, the optimal power of WT to feed PEMEL is to be approximately two times PEMEL powered. Also, PV system is designed to be equal to PEMEL power. This study will be a reference for designing PV or WT to feed an electrolyzer.
