With direct electricity, the water electrolysis technology provides pure hydrogen and oxygen from water. Zero-carbon recycling can be achieved with hydrogen as the energy carrier. Unstable renewable energy can be stored in hydrogen. With the concept of power-to-gas or power-to-liquid, high efficiency and zero emission are realized during energy conversion. It is a promising energy utilization solution for the human society in the future. In this review, the water electrolysis technology for industrial hydrogen production is investigated. The progress on proton exchange membrane (PEM) water electrolysis is summarized. Further, the future research trend of water electrolysis is discussed. Additionally, suggestions for hydrogen production from water electrolysis are provided.
