The Baowu Clean Energy (Yangjiang) Green Hydrogen Industrial Park was officially launched recently. This project has garnered significant attention not only for its total investment of 11.09 billion RMB and its planned annual production capacity of 80,000 tons of green hydrogen, but also, more importantly, for the simultaneous construction of three hydrogen transmission pipelines—a development that marks a pivotal milestone in the history of China's green hydrogen industry.
The project is invested in and constructed by China Baowu Clean Energy Co., Ltd. The overall plan encompasses green hydrogen production, the downstream utilization of green ammonia and green methanol, manufacturing of hydrogen production equipment, solid-state hydrogen storage materials, and an innovation R&D center. Central to the project are three hydrogen transmission pipelines connecting Yangjiang to Zhanjiang, the Pearl River Delta, and Hong Kong, which will establish the first large-scale green hydrogen distribution network in the Greater Bay Area. This also marks the official implementation of China's first integrated project combining "direct hydrogen production from offshore wind power with pipeline network transmission," moving green hydrogen from the demonstration and validation phase into a new cycle of industrialized supply.
For the valve industry, this represents more than just the launch of a single energy project; it is a clearly visible and accelerating demand curve for high-end equipment.
Within the hydrogen energy chain, hydrogen transmission pipelines are widely regarded as one of the segments with the highest technical barriers and the most stringent system safety requirements. Hydrogen molecules are small and highly permeable, and under high pressure, they can easily induce hydrogen embrittlement in materials. This presents multiple extreme challenges for valves, including the selection of hydrogen embrittlement-resistant materials, ultra-high sealing grades, and zero-leakage structural designs. Consequently, hydrogen pipeline networks have become the most concentrated application scenario for high-end valves.
The three hydrogen transmission routes planned for this Yangjiang project—serving the green hydrogen substitution needs for Zhanjiang Iron and Steel, industrial hydrogen demand in the Pearl River Delta, and the future hydrogen city development in Hong Kong—signify that China's first batch of large-scale, long-distance hydrogen pipelines has officially entered the construction phase. The corresponding valve demands span multiple high-end niche categories, including high-pressure fully welded ball valves, low-temperature shut-off valves, pressure regulating valves, Emergency Shut Down (ESD) valves for stations, ultra-high-pressure hydrogen storage valves, and online hydrogen leak detection valve manifolds. Based on industry experience, the valve market size, considering only the pipeline itself and the station systems, is expected to exceed the 1 billion RMB level, and this is merely the first phase of the project.
Simultaneously, with the advancement of the hydrogen production equipment base, the demand for process valves will also experience a "cluster-style explosion." The project plans to build a 1.5 GW offshore wind power direct-connected hydrogen production system, with megawatt-scale water electrolyzers operating on a large scale. This means a significant number of electrolyzers, gas-liquid separation systems, purification systems, drying systems, and compression systems will be put into use concurrently. Consequently, specialized corrosion-resistant valves for electrolyzer inlets/outlets, safety shut-off valves for oxygen-hydrogen separation, high-purity diaphragm valves, high-temperature control valves, and compressor anti-surge valves will become standard configurations in hydrogen production systems. These valves typically require oil-free operation, no contamination, ultra-high sealing integrity, long life, and low maintenance, which is driving the rapid expansion of domestic high-end process valves from traditional petrochemical fields into hydrogen energy systems.
Even more forward-looking is the project's simultaneous layout of a solid-state hydrogen storage materials base, which opens up a brand-new niche track for specialty material valves. Solid-state hydrogen storage involves high-temperature hydrogen absorption/desorption reactions, powder material conveying, and inert gas protection systems, imposing composite requirements on valves such as high-temperature resistance, wear resistance, suitability for powder media, and highly reliable isolation. Products like high-temperature wear-resistant butterfly valves, diverter valves for powder service, and inert gas isolation valves will see initial demand formation in this area, which was previously almost non-existent domestically.
Against the backdrop of accelerated industrial implementation, whether valve companies can enter this emerging supply chain hinges on three clear pathways. First, proactively engage with the design and EPC lead units for the hydrogen pipeline network and hydrogen production units to participate in formulating technical specifications. Second, establish a certification system for "hydrogen service valves," passing critical tests for hydrogen embrittlement resistance, sealing life, and Class VI leakage rates. Third, build localized service and intelligent operation and maintenance capabilities to secure long-term orders through lifecycle services. Currently, the number of domestic enterprises with comprehensive hydrogen valve technology and certification capabilities is still limited, and technical barriers are rapidly transforming into profit barriers.
From a broader industrial perspective, hydrogen infrastructure is replicating the development path of the natural gas pipeline network from two decades ago. Twenty years ago, the "West-East Gas Pipeline" project propelled the comprehensive rise of domestically manufactured high-pressure pipeline valves. Today, the green hydrogen transmission network is opening a new track with a higher starting point, higher thresholds, and greater concentration.
The significance of the Baowu Clean Energy (Yangjiang) project extends far beyond its 80,000-ton annual green hydrogen production capacity; it lies in the official realization of China's first green hydrogen pipeline network blueprint. With the full-scale construction of hydrogen transmission pipelines underway, the race for the domestic substitution of high-end hydrogen service valves has only just begun. For the valve industry, this is a critical window of opportunity not to be missed, and the moment of opportunity is already clearly in sight.
