Dutch Estonian startup Spiral Hydrogen will build its first centrifugal bubble-free electrolyser system in the Port of Rotterdam. The 10kW pilot is supported by €2.7 million in pre-seed funding from leading Nordic and European investors and marks a major milestone on the path to commercial scale.

Conventional electrolysers lose up to 30% of input energy because gas bubbles form on the electrodes and block active reaction sites. Spiral Hydrogen founders Juri Volodin and Fedor Stomakhin say their patent-pending architecture eliminates bubble formation by harnessing centrifugal force to route gases directly through hydrophobic porous electrodes into dedicated dry gas channels.

The result is efficiency over 90% and a significant lowering of the levelised cost of hydrogen, making green hydrogen “cheaper than fossil alternatives for the first time.”

The pilot will be carried out in partnership with SwitcH2, purveyor of floating production units for green hydrogen and green ammonia. SwitcH2 is a subsidiary of BW Offshore and Dutch Oceans Capital.

Mr Volodin holds two MScs from the European Wind Energy and Electrical Power Systems program (TU Delft and NTNU). Mr Stomakhin holds an MSc in Data Science.
