Abstract

Each of the four water electrolysis technologies has its own advantages and limitations. Alkaline water electrolysis is mature and suitable for large-scale, stable industrial applications. Proton exchange membrane electrolysis is well-suited for integration with renewable energy sources due to its fast response, though it remains relatively expensive. Solid oxide electrolysis offers high efficiency and can utilize high-temperature heat sources, but improvements in material and system stability are needed. Anion exchange membrane electrolysis offers cost advantages and strong development potential but still requires breakthroughs in materials and system design. In the future, selecting the most appropriate electrolysis technology based on specific application scenarios will be crucial for advancing the sustainable development of the hydrogen energy industry.
