About

pHydrogen is a University of Tokyo spin-off developing seawater electrolysis systems that use earth-abundant metals such as iron instead of scarce catalysts, aiming to sharply cut the production cost and capital investment of green hydrogen. Its core innovation is a proprietary near-neutral-pH electrolyte that lets cheap metals work in seawater while matching the performance of conventional alkaline electrolyzers. Founded in 2025 in Tokyo by CEO Takahiro Tobita and CTO Kazuhiro Takanabe (a University of Tokyo professor), the company raised a ¥300 million (~$2M) seed round from Incubate Fund in June 2025 to scale up its electrolysis system and pursue business partnerships.
