Green hydrogen is gaining prominence in the global energy sector for its role in achieving carbon neutrality and sustainable development. In China, the growth of green hydrogen projects is driving the demand for water electrolysis hydrogen production equipment. The delivery volume in China reached 1,844.51 MW by the end of 2024, showing rapid growth for five consecutive years and a projected increase to 2,500 MW in 2025. Large-power equipment is preferred to improve efficiency and reduce costs, emphasizing the need for performance and safety testing. Despite industry innovation, few companies can test 10 MW-level equipment adequately. To meet increasing demands, Changzhou Better Test & Control collaborates with the National Hydrogen Energy Center to develop advanced on-site testing equipment. This partnership marks a significant advancement in China's testing capabilities for hydrogen energy equipment, supporting the global energy transition. The testing equipment offers exceptional capabilities, detecting key parameters of hydrogen production systems with precision. Its modular design allows flexible deployment for on-site measurements, addressing testing constraints effectively. With multiple safety interlock systems, the equipment ensures the safety of personnel and data, meeting industry standards. The collaboration between Better Test & Control and the National Hydrogen Energy Center provides electrolyzer enterprises with standard-compliant durability reports and certifications, facilitating product market entry. This initiative not only boosts the green hydrogen industry but also underscores China's commitment to innovation, sustainability, and energy transformation.
