Hydrogen as an energy source has been identified optimal pathway for mitigating climate change by combining renewable electricity with water electrolysis systems. Proton exchange membrane (PEM) technology received a substantial amount of attention because its ability to efficiently produce high-purity hydrogen while minimising challenges associated handling and maintenance. Another generation technology, alkaline (AWE), widely used in commercial production applications. Anion (AEM) can at relatively low costs the noble metal catalysts PEM AWE systems are replaced conventional low-cost electrocatalysts. Solid oxide electrolyzer cell (SOEC) is another producing high conversion efficiencies, cost, emissions. However, operating temperatures SOECs which necessitates long startup times. This review addresses current state technologies capable using impure Commercially available were extensively discussed compared. The technical barriers AEM also investigated. Furthermore, stack performance was evaluated artificial river (soft water). An integrated system approach recommended meeting power pure demands reversible seawater electricity, electrolysis, fuel cells. considered be low, requiring further developments enhance membrane's lifetime.
