Spiral Hydrogen
Deeptech startup developing bubble-free electrolysis technology for efficient green hydrogen production.
About
Spiral Hydrogen is an Estonian-Dutch deeptech startup focused on revolutionizing green hydrogen production. They have developed a proprietary rotating, bubble-free electrolysis technology designed to significantly improve the efficiency of hydrogen generation. Unlike conventional electrolyzers that suffer from energy loss due to gas bubbles forming on electrodes, Spiral Hydrogen's approach routes gases through a porous electrode into a dedicated channel.
