The seawater electrolysis for hydrogen production has a wide range of raw materials, which can effectively couple with marine new energy to reduce the cost of offshore electricity, and has become a hot topic in the hydrogen production industry. However, the deposition of Mg2+ and Ca2+, as well as the corrosion of chlorides on the electrolysis cell, hinder the large-scale application of seawater electrolysis hydrogen production technologies. Therefore, improving hydrogen production technologies and developing new electrode materials to reduce the impact of impurities in seawater have become the focus of research and development for seawater electrolysis hydrogen production. Firstly, the main components of seawater and their impacts on the performance and lifespan of seawater electrolysis systems were analyzed. The advantages and disadvantages of different electrolysis seawater hydrogen production technologies were discussed, as well as research progress. It is believed that electrolysis seawater hydrogen production technologies still mainly rely on hydrogen production after seawater purification. Then, the electrode materials for seawater electrolysis were summarized, including precious metal materials, transition metal compound catalytic materials, and new structural materials. Among them, transition metal compound catalytic materials have good development prospects. Finally, the challenges and prospects faced by the industrial application of seawater electrolysis hydrogen production technologies were discussed, and it is pointed out that combining the research results of efficient and long-life transition metal compound catalytic materials, as well as the hydrogen production technologies after seawater purification, will be the development direction of seawater electrolysis in the future.
