There are several approaches to produce a renewable hydrogen [5]. Among these methods, water electrolysis is a process in which the electrical energy is converted into chemical energy. When water electrolysis is implemented using renewable energy (e.g. Hydro, Wind, and Solar) the hydrogen can be considered as an entirely renewable and clean energy carrier. Water electrolysis offers several advantages over other production methods such as steam reforming. Water electrolysis gives very pure hydrogen with no carbon emissions as no dependence on hydrocarbon sources.
