Green hydrogen, as a shining star in the clean energy sector, is gradually becoming a significant force driving the transformation of the global energy structure. Its production process is zero-emission with high energy conversion efficiency, holding immeasurable value for achieving carbon neutrality and promoting sustainable development. It is leading the energy industry toward a greener and low-carbon future. The water electrolysis hydrogen production system, as the core equipment for green hydrogen production, plays a crucial role in the development of this green energy.
With the accelerated development of green hydrogen in China, green hydrogen projects are flourishing, and the demand for water electrolysis hydrogen production equipment continues to rise. According to SMM data, as of December 31, 2024, the domestic delivery volume of water electrolysis hydrogen production equipment reached 1,844.51 MW, up 67.68% YoY, achieving five consecutive years of rapid growth. It increased from 185 MW in 2020 to surpassing 1 GW for the first time in 2023, and further to 1,844.51 MW in 2024, showcasing the robust momentum of hydrogen production systems in China. It is expected that in 2025, the delivery volume of water electrolysis hydrogen production equipment will reach 2,500 MW, with a growth rate exceeding 40%.
As the delivery volume of water electrolysis hydrogen production systems continues to increase and the demand for end-user green hydrogen projects grows, large-power water electrolysis hydrogen production equipment has become the preferred choice for improving hydrogen production efficiency and reducing costs. According to SMM statistics, among the 600 MW of water electrolysis hydrogen production equipment awarded in 2024, 60 MW of projects adopted hydrogen production equipment with a capacity of over 10 MW. Under such circumstances, ensuring the performance and safety of these hydrogen production systems has become the industry's primary concern, highlighting the growing importance of test data.
However, in the current hydrogen production testing equipment market, although many companies are continuously innovating, there are very few enterprises capable of testing 10 MW-level equipment. Large-power megawatt-level testing equipment faces dual constraints of site and power supply requirements, with only a handful of electrolyzer manufacturers meeting the conditions. In the past, the electrolyzer industry often adopted reverse R&D thinking, conducting only basic gas-tightness detection and then collecting operational data on-site. However, end-user customers now require electrolyzer manufacturers to provide third-party certifications and durability-related test reports. Self-built testing platforms or on-site testing methods can no longer meet current customer demands.
For megawatt-level electrolyzers, authoritative third-party institutions are required to provide testing and certification. Third-party platforms not only need sufficient power supply capacity but also appropriate testing equipment. Amid the expanding demand for large-power megawatt-level testing equipment and increasingly stringent requirements, Changzhou Better Test & Control Technology Co., Ltd. (Better Test & Control) has partnered with the National Hydrogen Energy Power Quality Inspection and Testing Center of China Automotive Engineering Research Institute Co., Ltd. (referred to as the National Hydrogen Energy Center) to jointly develop on-site testing equipment for water electrolysis hydrogen production systems, successfully achieving technical validation recently.
The successful validation of this equipment signifies that China's large-power testing capability for hydrogen energy equipment has reached an internationally leading level, providing critical data support for the large-scale application and safety assurance of green hydrogen, and contributing to the deep transformation of the global energy structure. As an innovation leader in the hydrogen energy testing field, Better Test & Control remains focused on the R&D and industrialisation of high-precision, high-reliability testing equipment. The water electrolysis hydrogen production system testing equipment developed in collaboration with the National Hydrogen Energy Center offers several core advantages:
First, outstanding testing capability. This equipment aims to fill the gap in domestic large-power hydrogen production system testing equipment, overcoming engineering bottlenecks in large-power testing equipment and meeting the testing needs of the National Hydrogen Energy Center for hydrogen production systems in the (0-10) MW power range.
Second, comprehensive detection of key parameters. The equipment can detect multiple key parameters of hydrogen production systems, including hydrogen and oxygen outlet pressure of the electrolyzer, electrolyzer voltage/current/power, cell voltage, electrolyzer inlet temperature, hydrogen production pressure, hydrogen production temperature, hydrogen flow rate, and oxygen concentration in hydrogen.
Third, flexible modular deployment. The equipment adopts a modular design, allowing modules to be assembled into a whole or disassembled for on-site measurement of hydrogen production systems, effectively addressing site constraints for testing.
Additionally, strict safety assurance. The equipment is equipped with multiple safety interlock systems to ensure the safety of the hydrogen production system's boundary conditions, the security of test equipment data, and the personal safety of testing personnel.
Moreover, authoritative collaboration. The equipment was jointly developed by the National Hydrogen Energy Center and Better Test & Control, receiving authoritative technical validation. It can provide electrolyzer enterprises with standard-compliant durability reports and performance certifications, helping customers quickly pass downstream end-user reviews and accelerating product marketisation.
Finally, strong technical capabilities for comprehensive support. In addition to water electrolysis electrolyzers and their hydrogen production system testing equipment, Better Test & Control also provides PEM fuel cell testing equipment, SOFC solid oxide fuel cell testing equipment, and customised services based on customer needs, earning an excellent reputation in the hydrogen energy market.
