Hydrogen storage systems are lauded for their high energy content and the fact that they produce zero emissions during use. They offer a potential solution for small- and large-scale storage and can be used in a variety of applications beyond electricity, such as in transportation. . Solar energy can be captured and converted into various forms, including electrical energy via photovoltaics (PVs), thermal energy through solar heating systems, and chemical energy in the form of solar fuels, in which the conversion of solar energy into chemical energy represents a promising. . For residents of Washington State, the benefits of solar energy storage extend beyond environmental stewardship. Net Energy Metering (NEM) policies allow consumers who generate their own electricity from solar power to feed excess energy back into the grid. Abundant in nature as water and hydrocarbons, hydrogen must be converted into a usable form for practical applications.
