Research on Development of Complete Alkali-Saline Water Electrolysis Equipment for Hydrogen Production and Its High-Value Utilization Technologies

Amid the global push for carbon neutrality, green hydrogen has emerged as a cornerstone of the energy transition toward renewable sources. However, electrolysis-based hydrogen production from saline-alkali water faces significant technical hurdles. This study tackles the dual challenges of saline-alkali water resources and wind-solar hybrid hydrogen generation in Xinjiang. The research proposes a "direct electrolysis of saline-alkali water" solution, develops a high-frequency PWM multi-modal control system for IGBT/SiC fast-response power supply, and innovatively designs a modular integrated device with gradient pore structures. Additionally, it introduces a coupled electrolysis-deuterium separation technology. These advancements not only reduce green hydrogen production costs but also enhance the recycling of saline-alkali resources, providing crucial technical support for building western green hydrogen bases to achieve carbon neutrality.
