Performance↑
Less power and electrode area for the same hydrogen output
Commercial AEM electrolysis, starting at 2 kW
AEM electrolysis built to lower clean hydrogen production costs.
We manufacture electrodes and stacks in-house and supply a commercial 2 kW system built around them. The manufacturing experience and operating data from products in the field now inform our 30 kW stack.

No single metric can lower the cost of clean hydrogen
Lower costs require better performance and durability, lower stack cost, and manufacturing that can scale.
Durability↑
Slower efficiency loss and fewer replacements
Stack cost↓
Lower core CAPEX for hydrogen production
Manufacturability↑
More capacity with consistent quality
Improved togetherClean hydrogen cost ↓
