Comparative Performance Evaluation of Solar and Wind based Electrolysis Systems for Green Hydrogen Production

The increasing demand for sustainable energy solutions has highlighted the potential of green hydrogen as a clean energy carrier. Solar or wind-powered electrolysis systems are considered promising technologies for producing green hydrogen, yet their efficiency is limited by intermittency issues. This study evaluates the performance of solar and wind-based electrolysis systems for green hydrogen production, focusing on hydrogen production rates, energy consumption, and system stability under varying environmental conditions. The solar-powered system’s hydrogen production fluctuates based on solar irradiance, with significant drops during low sunlight periods, while the wind-powered system demonstrates more stable hydrogen production due to the continuous availability of wind energy. The contribution of this paper is comparative analysis of these two renewable energy sources using MATLAB simulations. We present a simulation model for both systems and evaluate their hydrogen production under both scenarios. The results show that the wind-based system produces approximately 110 kg of hydrogen per day, while the solar system generates 80 bars of hydrogen by the end of day. These simulation results highlight the advantages of wind energy for consistent hydrogen production, while solar systems face challenges related to intermittency.
