Recently, TÜV Rheinland Greater China (TÜV Rheinland) held a certification ceremony in Hefei, awarding the hydrogen safety certification to the “SHM1000A Pressure-Type Alkaline Water Electrolysis Hydrogen Production System” of Sungrow Hydrogen Sci. & Tech. Co., Ltd (Sungrow Hydrogen) based on 2PfG CH0031. This demonstrates the leading safety performance of Sungrow Power Hydrogen’s flexible hydrogen production system and marks a significant milestone in its safety field.

During the certification process, TÜV Rheinland conducted a comprehensive safety assessment of Sungrow Hydrogen’s system based on best engineering practices from China, Europe, and the United States, combined system analysis and testing verification. Beyond regular certification tasks, the evaluation also comprehensively covered the entire lifecycle of the hydrogen production system and its key subsystems. This includes assessment of the design of key subsystems, control evaluation of the hydrogen production system manufacturing process, and operational safety compliance in predetermined application areas.

“Congratulations to Sungrow Hydrogen’s alkaline water electrolysis hydrogen production system on receiving the hydrogen safety certification. This proves that its system design safety has reached the advanced industrial standards,” said Dr. Chen Weikang, Vice President of TÜV Rheinland Greater China Industrial Service & Cybersecurity. “Especially the intelligent hydrogen management system’s monitoring, early warning, and control functions can not only improve the operating efficiency of the hydrogen production system but also add another layer of safety protection.”

As a wholly-owned subsidiary of Sungrow Power Co., Ltd. (Sungrow Power), Sungrow Hydrogen was established in June 2021, focusing on research on renewable energy water electrolysis hydrogen production technology. Its main products include hydrogen production power supplies, alkaline water electrolysis cells, PEM electrolysis cells, gas-liquid separation and purification devices, intelligent hydrogen management systems, etc., committed to providing “efficient, intelligent and safe” green electricity hydrogen production systems and solutions.

Sungrow Power is a company specializing in the research, development, production, sales, and service of new energy sources such as solar, wind, and energy storage. Over the past decade, it has established a deep and stable partnership with TÜV Rheinland in various fields. In recent years, Sungrow Power has continuously focused on the field of hydrogen energy, and the two parties have expanded their cooperation to the field of hydrogen safety. In March 2021, TÜV Rheinland and Sungrow Power signed a hydrogen safety strategic cooperation agreement. Both parties further deepened their cooperation surrounding the system safety evaluation of renewable energy hydrogen production equipment, green hydrogen evaluation, information security, etc., jointly promoting the safe and sustainable development of hydrogen technology.

Highlights of TÜV Rheinland’s Hydrogen Industry Chain Technical Services:

In 2021, TÜV Rheinland released the “Hydrogen Technology Roadmap,” showcasing one-stop professional technical services from hydrogen production to application, covering the entire value chain of hydrogen production, storage, transportation, application, including hydrogen production system safety and green, hydrogen storage systems, valves, pipelines, hydrogen cylinders, refueling stations, fuel cell vehicles, supply chain, etc., providing technical support and safety protection for entreprises at all stages of the hydrogen industry chain.

TÜV Rheinland has comprehensive hydrogen industry chain technical services, including in the three major areas of safety, quality, and decarbonization. Especially in the field of water electrolysis hydrogen production systems, TÜV Rheinland released the ‘Water Electrolysis Hydrogen Production System Safety Technical Requirements Guide’ (Technical Standard 2PfG CH0031) in April 2022 and updated and released the TÜV Rheinland Low Carbon Hydrogen Standard H2.21 V2.0 in 2022, setting requirements and application guidelines in terms of safety, low carbon, and efficiency management for green hydrogen utilization water electrolysis hydrogen production systems, helping to improve the safe, green, and sustainable application development of hydrogen production systems.

In the future, TÜV Rheinland will continue to utilize its rich experience in testing and certification, its global network of experts, advanced laboratory resources, high-end technology, and innovative methods to provide technical support and safety protection for the hydrogen industry chain, including Sungrow Hydrogen, and help promote the safe, intelligent, and sustainable development of the hydrogen industry.
