In the context of global energy structure transformation and dual-carbon strategy implementation, green hydrogen, as a zero-carbon, high-energy-density and storable clean energy, has been vigorously developed by major economies around the world in 2026. Green hydrogen produced by renewable energy electrolytic water has the advantages of zero carbon emission in the whole life cycle, which can effectively solve the energy storage and peak regulation problems of wind and solar new energy, and is widely used in industrial hydrogen production, transportation energy supply and power peak regulation fields. The large-scale popularization of green hydrogen energy depends on the technical upgrading and cost reduction of electrolytic water hydrogen production equipment.
Electrode material is the core key of electrolytic water hydrogen production equipment, and its conductivity, corrosion resistance and catalytic performance directly affect the hydrogen production efficiency and comprehensive energy consumption of the equipment. Traditional electrolytic water hydrogen production equipment mostly uses metal electrodes such as nickel-based and iron-based electrodes. In the long-term alkaline electrolysis and acidic electrolysis environment, metal electrodes are prone to electrochemical corrosion, surface oxidation and catalytic activity attenuation, resulting in reduced hydrogen production efficiency, increased equipment energy consumption and shortened service life. Frequent electrode replacement increases the operation cost of hydrogen production enterprises and restricts the large-scale promotion of green hydrogen energy.
Graphite-based composite electrode materials have completely broken through the performance limitations of traditional metal electrodes and become the optimal innovative materials for modern electrolytic water hydrogen production equipment. High-purity graphite materials have excellent electrical conductivity, stable chemical properties and strong electrochemical corrosion resistance, and can work stably in long-term electrolytic environment without oxidation and corrosion. Through surface catalytic modification and composite material optimization, graphite-based electrodes have excellent hydrogen evolution catalytic activity, which can effectively reduce the electrolytic reaction threshold, improve water electrolysis efficiency and reduce unit hydrogen production energy consumption.
Compared with traditional metal electrodes, graphite-based composite electrode materials have obvious comprehensive advantages. First, the corrosion resistance is strong, and the service life is more than 5 times that of traditional metal electrodes, which greatly reduces equipment maintenance and replacement costs. Second, the catalytic performance is stable, and the hydrogen production efficiency remains stable after long-term operation, avoiding efficiency attenuation caused by electrode aging. Third, the energy consumption is low, and the unit hydrogen production energy consumption can be reduced by 10-15%, with significant energy-saving benefits. Fourth, the cost advantage is prominent, and the comprehensive use cost is far lower than that of precious metal electrodes.
With the large-scale construction of global green hydrogen projects, the market demand for high-performance graphite-based hydrogen energy electrode materials has exploded. According to industry statistics, the global market size of hydrogen energy graphite electrode materials will maintain a compound annual growth rate of 14.2% from 2026 to 2030, with huge market space. At present, the technical threshold of modified graphite electrode materials is high, and there are few mature suppliers in the global market, resulting in a prominent market supply gap.
