The cheapest hydrogen is green

Spiral Hydrogen delivers green hydrogen at lower cost — and zero emissions.

The world already runs on hydrogen.

It is a €215B global industry.

Oil refining requires 43Mt of hydrogen every year. Fertilizers, plastics and steel production add another 55Mt.


And that's even before we get to transportation and energy production.

The market wants to decarbonize.

But the costs don't allow it.

There is a large price gap between green and fossil-based hydrogen, preventing the market from going green.


Despite regulatory pressures, less than 1% of global hydrogen production is fossil-free.

Introducing a novel electrolyzer

This device uses rotation for circulating liquids and works without producing gas bubbles.


It sets a new standard in electrolysis.

Bubble-free electrolysis

95% efficiency (HHV)

Gases can escape through porous electrodes to the dry side.

Centrifugal pumping

up to 3A / cm²

Rotation circulates liquids efficiently, allowing high current densities.

In-situ catalyst re-deposition

>30y lifetime

Rotation helps create a uniform deposit of the catalyst.

This brings the cost of green hydrogen below fossil hydrogen
