How it works
Bubble-free electrolysis
Our design keeps electrodes clear of bubbles, enabling >95% efficiency.
Centrifugal circulation
Rotation naturally pumps and cools the electrolyte, eliminating the need for external pumps or separate cooling loops.
High power density
Exceptional mass transport supports ~3.0 A/cm² at 95% efficiency — several times higher than conventional alkaline systems.
>90%
HHV efficiency of our Alkaline cell
Up to
3A
current density per cm²
Approx.
10s
startup time, suitable for renewables
