The Battle for Green Hydrogen Supremacy
The global race for clean energy dominance has entered a new phase, with electrolysers emerging as the critical technology that could determine which nations lead the green hydrogen revolution. These sophisticated devices, which use electricity to split water into hydrogen and oxygen, occupy the same strategic position in hydrogen production that photovoltaic modules held in the solar boom—making them central to the world’s decarbonization efforts.
As governments worldwide commit to net-zero emissions and industries seek alternatives to fossil fuels, a familiar question emerges: Can China replicate its stunning solar dominance in the global electrolyser market? The early signs suggest a resounding yes, with Chinese companies already capturing 85% of the alkaline electrolyser market and leveraging the same strategies that made them solar powerhouses.
This dominance carries profound implications for global energy security, technological sovereignty, and the pace of decarbonization worldwide. With electrolysers required to scale from current capacity to potentially 4,000 GW by 2050, the companies and countries controlling this technology will shape the future of clean energy.
The Strategic Importance of Electrolysers in Green Transformation
Electrolysers as the Hydrogen Economy’s Foundation
Electrolysers function as the critical bridge between renewable energy and industrial decarbonization by converting clean electricity into storable, transportable hydrogen. Much like how photovoltaic modules democratized solar power generation, electrolysers are becoming the enabling technology for industries ranging from steel production and ammonia synthesis to long-duration energy storage and heavy transportation.
Two primary electrolyser technologies dominate the current market:
Alkaline Electrolysers (ALK):
- Mature, lower-cost technology with 40+ years of development
- Less efficient under fluctuating loads limiting renewable energy integration
- China’s primary strength with vertically integrated supply chains
- Price advantage of up to 65% compared to Western alternatives
Proton Exchange Membrane (PEM) Electrolysers:
- Higher efficiency and better compatibility with intermittent renewables
- Superior hydrogen purity (99.999%) essential for advanced applications
- Higher costs due to precious metals like platinum and iridium
- Western technological leadership with ongoing Chinese investment
Industrial Applications Driving Demand
The global hydrogen market of 97 million tonnes in 2023 demonstrates massive existing demand that green hydrogen must capture. Key industrial applications include:
Chemical Industry:
- Ammonia synthesis consuming 26% of China’s hydrogen (9.5 million tonnes)
- Methanol production accounting for 27% of domestic consumption (9.95 million tonnes)
- Refining processes utilizing 16% of hydrogen supplies (6 million tonnes)
Steel and Heavy Industry:
- Direct reduction of iron ore replacing coal-based processes
- High-temperature heat applications for industrial processes
- Clean fuel for heavy-duty transportation and shipping
