A Sizing and Dynamic Model for a Green Hydrogen as Energy Storage Technique for the Hybrid System 50KW Solar PV with PEM Fuel Cell

In this paper, the optimal size of solar PV, PEM fuel cell and hydrogen tank is performed by using HOMER Pro software. The PEM fuel cell is used to consume the hydrogen gas which is generated by an electrolyzer. The simulation is aimed to analyze the feasibility and performance of the system, considering some factors such as energy generation, storage, and consumption. The simulation results are specified valuable insights into the potential benefits and challenges of using hydrogen gas as an energy storage method in hybrid renewable energy systems. The optimization study was conducted to design the required hydrogen storge is 30kg H2 and the capacity of the PEM fuel cell is 30kWand the integration of a water electrolyzer with a capacity of 30kW. where the economical simulation shows that the levelized cost of energy is $0.126/kWh.
