Abstract: Electrolytic hydrogen production using renewable sources can play a central role in global decarbonization. However, the direct coupling of electrolyzers with renewable energies can cause frequent shutdowns and high production fluctuations unless adopting electrical storage systems or using electricity from the grid that is generally not completely decarbonized. In this study, a system consisting of a wind turbine, short-term battery storage, and an alkaline electrolyzer was analyzed through annual simulations in MATLAB. A power management strategy sets the electrolyzer and battery operating conditions. Firstly, several battery and electrolyzer sizes were investigated for a given wind site for three scenarios (0%grid, 20%grid, and 100%grid) in which the grid guarantees the electrolyzer operation at a minimum load of 0%, 20%, and 100%, respectively. Secondly, the effect of the wind speed distribution on the system performance was investigated by comparing sixteen different wind sites in the 0%grid scenario. The battery presence always led to a LCOH increase. The 20%grid scenario represented a good compromise between the minimization of specific CO2 emissions, and the minimization of LCOH (that was always lower compared to the 0%grid scenario and the lowest without battery). The shape parameter of the fitted Weibull wind speed distribution did not affect the system. Instead, a greater scale parameter led to both greater hydrogen production and a lower LCOH.
