Green hydrogen production at industrial scale.
Knergy offers a proprietary dual electrolyzer portfolio — Hydrobooster ALK and Hydrobooster PEM — carefully engineered to cover the full spectrum of industrial green hydrogen applications: from continuous 24/7 operation in heavy plants (where alkaline technology is optimal) to coupling with intermittent renewables (where PEM technology stands out for its fast response).
Both lines are Knergy products
Both lines are Knergy products: in-house engineering, proprietary balance of plant integration, functional safety systems certified to IEC 62061 SIL2/SIL3, native integration with the client's COP, and a pure-lease financial model at 5%. Knergy helps the client choose the right technology for their application — not the one most convenient for us to sell.
A real product, manufactured and integrated by Knergy
Cell manufacturing, proprietary balance-of-plant integration, and containerized Hydrobooster units ready to operate on site.
Two technologies, one honest technical decision
Every application has an optimal technology. The comparison summarizes where each line of the Hydrobooster portfolio stands out.
| Criterio | Hydrobooster ALK | Hydrobooster PEM |
|---|---|---|
| Operating regime | Continuous 24/7 operation, heavy industry | Variable load, coupling with renewables |
| Response time | Wide modulation for stable process | Fast response (< 3 s) |
| Cost per kW | Low cost per kW installed | Higher due to power density and materials |
| Service life | Long service life (80,000–100,000 h) | Optimized for start/stop cycles |
| Scale | MW scale · complete multi-MW plants | Compact · immediate high purity |
Choose the right technology for your application
