TheHydrogenElectrolysisModel Thehydrogenelectrolyzer transfers redundantenergy, i.e., theextra-renewableenergywhenthe batterySOCisnear100%, intohydrogenwhenthepowersupply isgreater thanthe load. Thestored hydrogen is thenconverted intoelectricitybyaPEMFCwhenthe loaddemandexceeds thepower supply. Therefore, a theoretical model can be built to estimate hydrogen production based on redundant renewable energy. Ahydrogen electrolyzer utilizes this redundant energy toproduce hydrogen. Thehydrogenelectrolyzation system is shown inFigure 4. It consists of a commercial hydrogen electrolyzer, HGL-1000U, with a rating energy consumption of 400W and hydrogen 198
