The quest to make green hydrogen economically viable just got a boost, as Spiral Hydrogen announced it has raised $3.2M in pre-seed funding. The startup is developing next-generation alkaline electrolyzers designed to overcome core problems plaguing current systems, aiming for efficiencies up to 95% and a stack cost an order of magnitude cheaper.
Spiral Hydrogen's technology, which eliminates gas bubbles and uses rotation to pump electrolyte, has been validated in lab conditions (TRL 4). The company's ultimate goal is to drive the price of green hydrogen below that of fossil hydrogen, unlocking a €250B market for decarbonization and making hydrogen transportation and heating commercially viable. This capital will support their journey towards building their first pilot (TRL 6).
