Hydrogen is an effective energy carrier for renewable resources, and this energy can be extracted from hydrogen through fuel cells and internal combustion engines. Hydrogen can also be used for energy storage, for example, during off-peak hours, excess electrical energy, instead of being wasted, could be stored in the form of hydrogen via electrolysis [ 2 ].
