Shanghai H-Ray Exports the First Chinese MW-Class CE-Certified PEM Water Electrolysis system, Delivered to South Africa’s ESKOM

On October 8, 2025, the "International Hydrogen Day", Shanghai H-Ray S&T Co., Ltd. (hereinafter referred to as "Shanghai H-Ray") announced that its MW-class PEM Water Electrolysis System, certified by EU CE, has been shipped overseas to a project site under ESKOM, South Africa's national power utility.

This marks the first overseas shipment of MW-class PEM hydrogen production equipment manufactured in China. The product meets the requirements of fluctuating operation scenarios for solar to hydrogen and features high integration, automation, and low energy consumption.

The high-purity hydrogen (Purity: 99.999%, Dew point: -75 °C) is mainly used in the hydrogen-cooled generator systems of thermal power plants, while the rest is supplied to nearby chemical enterprises through the park's pipeline network. This represents significant progress of domestic MW-class PEM hydrogen production equipment in the field of industrial applications.

Shanghai H-Ray's MW-class PEM skid-mounted water electrolysis system adopts an "All-in-One" modular and serialized design. The product has successfully obtained EU CE certification, and its safety, reliability, and operational requirements fully comply with the strict use-conditions of power and chemical enterprises as well as the risk management standards for hydrogen production processes.

Dalin Hu, vice president of Shanghai H-Ray, stated: "We are very pleased to provide tailored solutions for ESKOM, South Africa's national power utility. High Purity hydrogen for power plant cooling is a market with clear demand and high requirements. Our RYZER® system not only produces hydrogen that meets high-purity standards (Purity: 99.999%, Dew point: -75 °C) but also perfectly adapts to the 24/7 continuous and fluctuating operation needs of power plants with its high level of automation and safety design. This successful cooperation with the South African power plant is a landmark achievement. While bringing economy and high reliability to the customer, it also ensures the safety of the user's site, laying a solid foundation for the continuous expansion of the overseas market." 

Core Parameter Advantages of the RYZER® Series PEM Water Electrolysis System:

· High Hydrogen Purity: It meets the long-term supply requirements of hydrogen with a purity of 99.999% and a dew point of -75 °C, which is superior to the application standards of generator hydrogen cooling systems and effectively protects precision power generation equipment.

· Wide Power Fluctuation Operation: The system operates in a range of 10%-120%, adjusting to changes in electricity prices and downstream demand for continuous and fluctuating operation, bringing tangible benefits to users.
· Safety Assurance: It integrates multiple active and passive safety measures and has obtained HAZOP certification and CE certification, ensuring absolute safety in the power plant environment. When the system operates at low load, the hydrogen concentration in oxygen is less than 0.25%.
· Economy: It has a measured DC power consumption of 4.04 kWh/Nm³H₂. Compared with purchased hydrogen, it has significant advantages in the total life cycle cost.

From the successful overseas bidding, review of the design and process flow, certification of materials and supervision of the production and manufacturing process, to the final factory performance testing and 7-day operation test acceptance, this entire process marks that Shanghai H-Ray has gained recognition in the international market of high-end industrial PEM water electrolysis, and also demonstrates the international image and quality of products "Made-in-China".
