Based on more than 20 years of six core technologies including power electronics and electrochemistry, and three core equipment: IGBT hydrogen production power supply, ALK/PEM electrolyzed water hydrogen production equipment, and smart hydrogen energy management system, Sunshine Hydrogen Energy has built a flexible, efficient and friendly renewable energy flexible hydrogen production system. The system has faster response capabilities, wider load operating range, higher operating efficiency, as well as outstanding grid friendliness and operation and maintenance friendliness, realizing the flexible integration of hydrogen production systems and wind, light, storage, grid and other energy forms and various application scenarios such as green electricity hydrogen production, hydrogen energy storage, and green chemical industry. At present, the products have been used in many fields such as energy and power, petroleum industry, and transportation, helping them achieve deep decarbonization. It not only has the advantages of small footprint, low initial investment, and rapid modular layout, but also realizes "load follows the source" through the smart hydrogen energy management system. The on-grid electricity does not exceed 20%, and no electricity is drawn from the power grid. He pointed out that the smart hydrogen energy management system, which won the German IF Product Design Award, has achieved coordinated control between multiple hydrogen production systems, between hydrogen production systems and multiple energy sources, as well as integrated "production, transportation and addition". System integration and management, linkage control between systems, thereby greatly improving operational efficiency and safety.
