Revolutionary design
Our patent-pending design combines efficiency, simplicity, and scalability.
Bubble-Free Electrolysis
Prevents gas buildup on electrodes, achieving over 90% hydrogen production efficiency compared to 60–70% in conventional systems.
Centrifugal Design
Naturally pumps and cools the electrolyte through rotation, eliminating the need for external pumps or separate cooling systems.
Axial Flux Generator
Coils on the rotor, magnets on the stator—no slip rings, compact, high-torque, and low-friction power generation.
Integrated and Self-Powered
Converts mechanical energy directly into electrical power for electrolysis, operating independently of external power sources.
Scalable and Low-Maintenance
Modular design for easy scaling and reduced maintenance costs.

Our journey
TRL 3 & 4: Lab-scale prototype working
First run in the lab. We produced hydrogen and made first measurements on efficiency.
First team off-site at Hydrogen Expo
We visited Hamburg, Germany to learn about the industry and gain valuable contacts.
TRL 1 & 2: First concepts drafted
Patent filed in the Netherlands
After months of hard work, we filed the patent for our technological breakthrough.
Public announcement
As the engineering team keeps working on the prototype, we start sharing our progress publicly.
Innovation Grant
The Estonian Business and Innovation Agency awarded us a grant to cover patenting costs.
Baltic Impact Accelerator
In partnership with Estonian Cleantech Association, we got granted trainings and support for growth.
