To meet Kyoto Protocol proposed CO2 decreased emission plan, developing renewable energy system is to decrease CO2 emission major strategy. The current international market every year hydrogen consumption is equal to 15% of transportation energy consumption. From this point of view, if use hydrogen instead of oil production as transportation energy. The hydrogen energy production will be quickly expanded and built to use hydrogen power as a hydrogen economic system. This thesis is concentrating on analysing hybrid renewable energy to produce hydrogen. It uses the software and design the hybrid renewable energy power system, which combine with electrolysis to produce hydrogen. It compares with solar energy, wind power and hybrid system to produce hydrogen and water quantity that can get a hydrogen system optimum design.
