In March 2026, China reached a milestone in green hydrogen: installed and under-construction annual capacity exceeded one million tonnes for the first time. Of this, 250,000 tonnes already operate; more than double the figure from late 2024. China still produces over 80 percent of its total hydrogen from coal. But the direction of investment has turned.
What green hydrogen is and why it remains difficult to produce
Hydrogen does not occur naturally. It must be produced, and the method determines its climate impact. Gray hydrogen is made through steam reforming of natural gas or coal gasification, releasing significant CO2 during production. Green hydrogen, by contrast, is made via electrolysis of water, powered exclusively by renewable electricity. This is chemically simple but economically challenging: green hydrogen costs globally between 7.45 and 8.34 US dollars per kilogram; gray hydrogen ranges from 1.37 to 4.37 dollars.
The decisive cost driver is the electrolyzer—the device that splits water into hydrogen and oxygen. China has systematically reduced their manufacturing costs in recent years: Chinese makers now offer electrolyzers for 200 to 400 US dollars per kilowatt, a fraction of Western prices. This cost reduction is the core of China's advantage.
Why China is accelerating now
Installed projects concentrate in three regions. In the northeast, particularly Jilin Province, 45.7 percent of China's total operating electrolyzer capacity already runs. In Songyuan, Jilin, China Energy Engineering Corporation (CEEC) started the world's largest integrated green hydrogen, green ammonia, and green methanol facility in December 2025: 750 megawatts of wind and solar power produce 45,000 tonnes of hydrogen annually, which becomes 200,000 tonnes of ammonia and 20,000 tonnes of methanol. Investment was roughly 4 billion US dollars.
In Inner Mongolia, China Longyuan Power operates a 600-megawatt wind and solar project. Sinopec plans a 400-kilometer pipeline from Inner Mongolia to Beijing to carry 100,000 tonnes of hydrogen per year. These are not pilot projects. In April 2026, a vice director of the National Energy Administration stated China had moved past the demonstration phase for green hydrogen and entered large-scale development.
What this means for climate and the global market
These figures require context. China produces over 33 million tonnes of hydrogen annually, more than 80 percent from coal. The 1.1 million tonnes of electrolyzer capacity corresponds to just over three percent of the total market. Full decarbonization of China's hydrogen economy lies far in the future.
What is shifting: China now uses green hydrogen for steelmaking, ammonia production, and port transport—precisely those industries where direct electrification is technically difficult. The Institut Montaigne, analyzing China's hydrogen policy internationally, describes China as a strategic actor building green hydrogen not from conviction but from industrial policy. For climate, the outcome is nonetheless positive.
For the global market, it matters that China's electrolyzer makers drive prices downward. Germany has reserved 9 billion euros for electrolyzers and pipeline infrastructure. According to the IEA Global Hydrogen Review 2026, globally installed electrolyzer capacity doubled in 2025 to over 4 gigawatts, driven largely by Chinese mega-projects.
In comparison: How fast energy technologies can scale
The closest parallel to China's electrolyzer expansion is the story of solar panels. In 1976, one watt of solar capacity cost roughly 100 US dollars; according to Lazard data, the price today is under 0.30 dollars. The price decline followed a learning curve: with every doubling of production, costs fell 20 to 25 percent. China accelerated this effect through mass production. The same pattern now appears in electrolyzers.
Europe offers a sober counterexample. Germany, which wanted to pioneer this, lags far behind China in installed capacity. This stems not solely from missing money but from long approval procedures, high capital costs, and absent state anchor customers. The IEA documents that global production goals for green hydrogen by 2030 still far exceed what is actually being built. In China, the relationship reverses: expansion outpaces international forecasts.
At this pace: Cost parity with gray hydrogen by 2030
If the roughly 900,000 tonnes under advanced construction come online as planned, China's operating green hydrogen capacity should exceed one million tonnes by end of 2027. The IEA projects that green hydrogen in regions with cheap renewable electricity can drop below two US dollars per kilogram by 2030—competitively priced with gray hydrogen. China would be the first country reaching this threshold at industrial scale.
What this means for climate protection: if green hydrogen in China displaces coal hydrogen in steel and ammonia factories, those are emission volumes electrification alone cannot achieve. The question is not whether but how fast this happens.
