Our Technology
Our Electrolyzer Technologies
GreenHydro is continuously innovating in electrolyzer technology, holding over 60 patents across stack, BOP, and auxiliary system designs.
Our dedicated R&D team, consisting of expert scientists and engineers, has been advancing GreenHydro’s alkaline, PEM, and AEM electrolysis technologies since 2012.
Alkaline Electrolysis
GreenHydro’s alkaline electrolysis is a proven and highly durable technology, with hundreds of systems deployed worldwide. Designed for large-scale hydrogen production, our alkaline solutions support projects at both megawatt and gigawatt levels—making it the most established and scalable electrolysis technology.
- High durability
- Cost-efficient
- Ideal for large-scale output
PEM Electrolysis
Proton Exchange Membrane (PEM) electrolysis is ideal for applications requiring flexibility in operation and smaller output capacities. GreenHydro’s PEM electrolyzers currently range from 5 to 300 Nm³/h per stack, with ongoing advancements toward 400 Nm³/h and beyond in the coming years.
- High efficiency
- Rapid response time
- Compact and adaptable design
AEM Electrolysis
GreenHydro’s Anion Exchange Membrane (AEM) electrolyzers offer a turnkey hydrogen production solution that balances efficiency, stability, and ease of operation. Precision-engineered and rigorously tested, our AEM systems support up to 100 Nm³/h (500 kW) of hydrogen production, making them well-suited for a variety of small to mid-scale applications.
- Flexible for intermittent power sources
- Greater tolerance for impurities
- Innovative and promising technology
