One of the most attractive features of hydrogen as an energy carrier is that it can be produced from abundant material like water. The use of electrolysis to produce hydrogen from water is an efficient method from small to large scales. Energy for supplying water electrolysis systems can be provided by photovoltaic arrays. During the daylight hours; the sunlight on the photovoltaic arrays converts into electrical energy which can be used for electrolyzer. The hydrogen produced by the electrolyzer is compressed and stored in hydrogen vessel and provides energy for the fuel cell to meet the load when the solar energy is insufficient. This study investigates a stand-alone power system that consists of 10 kW PV arrays as power supply and 5 kW electrolyzer. They have been integrated and worked at Taleghan site in Iran. Result was simulated and optimized by using HOMER simulation tools and techno-economic analysis of system presented in this paper.
