Performance Evaluation of Wind-Powered Electrolysis Systems with Energy Storage for Green Hydrogen

Reducing carbon emissions is an important goal worldwide, which has increased interest in producing green hydrogen using renewable energy. Wind energy is a common renewable source that can power water electrolysis to generate green hydrogen. However, wind energy is not constant and changes frequently, making it hard to provide a steady power supply needed for efficient hydrogen production. This study uses MATLAB simulations to evaluate wind-powered electrolysis systems, comparing systems powered only by wind with those combined with battery energy storage. The study examines important factors such as current stability, hydrogen production rates, and energy use under changing wind conditions. The results show that adding energy storage helps reduce power fluctuations and keeps the electrolyzer working steadily, which leads to more consistent hydrogen production. Over the simulation period, the system with energy storage produced about 110 kg of hydrogen while using just over 6 kWh of energy for each kilogram produced. These results show that energy storage can effectively handle the unpredictable nature of wind energy, improving the stability and efficiency of hydrogen production compared to systems using only wind power. This research confirms that combining wind energy with batteries is a practical and effective way to improve green hydrogen production systems.
