VERDE HYDROGEN system hits commercial operation at 5,000 Nm³/h in China

VERDE HYDROGEN says its asymmetric five-to-one water electrolysis system at the Yongli Hydrogen Plant in Ningdong has moved from demonstration to sustained commercial operation after more than 760 days. The project is now producing and selling hydrogen at full load, signaling a step forward for large-scale green hydrogen deployment.

Why it matters: - The Yongli Hydrogen Plant’s move to sustained commercial operation shows that large-scale alkaline electrolysis can run reliably at industrial scale. - The project is a field test for centralized multi-electrolyzer systems that could support future hundreds-of-megawatts and gigawatt-scale green hydrogen projects. - The plant’s full-load output is now tied to external hydrogen sales, which makes the project commercially relevant, not just technical.

What happened: - On September 9, 2026, the Yongli Hydrogen Plant at the Ningdong Energy and Chemical Industry Base reached full-load hydrogen production of 5,000 Nm³/h. - All hydrogen produced at full load was supplied to external customers. - VERDE HYDROGEN supplied the core hydrogen production system. - The company’s system scope included architecture, alkaline electrolyzers, gas-liquid separation, hydrogen purification, balance-of-plant integration, and multi-electrolyzer intelligent control. - The plant uses five 1,000 Nm³/h-class alkaline electrolyzers. - The system marks China’s first large-scale asymmetric “Five-to-One” water electrolysis hydrogen production system to transition from demonstration operation to sustained commercial operation.

The details: - The project’s total hydrogen production capacity is 5,000 Nm³/h. - The designed annual output is about 1,428.6 tonnes of high-purity green hydrogen. - Hydrogen purity has remained above 99.999% during operation. - After optimization and full-capacity operation, overall production capacity increased by about 70%. - Overall energy consumption decreased by about 16%. - The complete hydrogen production system has operated safely and stably for more than 760 days. - The “Five-to-One” design uses five large-scale electrolyzers with one centralized auxiliary system. - Compared with a conventional one-electrolyzer, one-auxiliary-system setup, the architecture reduces redundant equipment, plant footprint, infrastructure investment, and long-term O&M requirements. - The system is designed for renewable-powered hydrogen production. - The project supports flexible load adjustment, intelligent start-up and shutdown, multi-electrolyzer coordination, and dynamic response to fluctuating wind and solar power.

Between the lines: - The 760-plus days of operation matter because they move the project beyond a short pilot and into a proven industrial reference point. - The combination of higher output and lower energy use suggests the design is improving both economics and operating efficiency. - The centralized architecture points to a possible scaling path for developers trying to lower complexity in larger green hydrogen plants. - VERDE HYDROGEN is positioning the project as validation of large-scale alkaline electrolysis and the business case for centralized multi-electrolyzer systems.

What’s next: - VERDE HYDROGEN says it will keep advancing large-scale water electrolysis, intelligent multi-electrolyzer integration, and renewable hydrogen solutions. - The company says those efforts are aimed at helping move green hydrogen from demonstration projects into commercial deployment. - The project’s performance may serve as a reference for future large renewable hydrogen installations.

The bottom line: - The Yongli Hydrogen Plant has turned a novel electrolyzer design into an operating commercial hydrogen asset, with 5,000 Nm³/h output, stable purity, and more than 760 days of safe operation.
