Spiral Hydrogen is building next-generation electrolyzers. Based on alkaline electrolyzers, we solve many core problems plaguing current systems. Our electrolyzers have no gas bubbles and achieve efficiencies up to 95%. We use rotation to pump our electrolyte, achieving current densities up to 3 A/cm². In addition, our stack cost is an order of magnitude cheaper, due to a simplified stack design and longer lifetime. Our goal is to get the green hydrogen price below fossil hydrogen, unlocking a €250B market for decarbonization and making hydrogen transportation and heating commercially viable. We have validated our technology in lab conditions (TRL 4) and are looking for pilot partners and investors to build our first pilot (TRL 6).
