The use of renewable energy to electrolyze water to produce hydrogen has been regarded as one of the most important methods to overcome the energy crisis and promote the healthy, orderly and sustainable development of the hydrogen energy industry, and is an important way to achieve the national "double carbon" goal. At present, in the hydrogen production technology of electrolyzed water, the related research of alkaline electrolyzed water for hydrogen production and proton exchange membrane electrolyzed water for hydrogen production technology has made important progress and initially realized the industrial application, high temperature solid oxide hydrogen production and the alkaline anion exchange membrane Hydrogen production technology is still in the experimental stage. Aiming at the technical bottlenecks existing in different electrolytic water hydrogen production modes, it is necessary to formulate a more reasonable research direction and plan through the combination of industry, education and research: for the relatively mature technology and low-cost alkaline electrolytic water hydrogen production technology, focus on solving problems such as low energy utilization efficiency, small amount of hydrogen in a single machine, and high energy consumption in operation; for the proton exchange membrane water electrolysis hydrogen production technology with high energy efficiency, good safety, and more adaptable to the fluctuation of renewable energy power, focus on the development of low-cost, key electrode materials and electrolysis systems with high activity and high stability, reducing the cost of hydrogen production and realizing the sinicization and large-scale application of key materials and components.
