<aside> 💡 pHydrogen Inc., established in Tokyo in 2025, is a company specializing in the development and sale of seawater electrolysis systems, led by CEO Takahiro Tobita and CTO Kazuhiro Takanabe.
The company's core technological innovation lies in its newly developed near-neutral electrolyte, a departure from conventional alkaline or acidic (PEM) types. This forward-thinking approach enables the production of green hydrogen by utilizing earth-abundant, inexpensive metals like iron and seawater, suggesting an aim to overcome the reliance on costly noble metals and freshwater prevalent in existing technologies.
A significant strength of this technology is its ability to employ affordable metals even in seawater environments, while having already reported performance comparable to alkaline systems. pHydrogen's solution centers on its innovative seawater electrolysis system, designed to substantially reduce hydrogen prices and initial investment costs, thereby contributing to the accelerated adoption of green hydrogen. The company differentiates itself primarily through its unique near-neutral electrolyte, which facilitates sustainable hydrogen production using readily available and inexpensive resources, serving as a powerful differentiating factor.
pHydrogen's business focuses on the development and sale of these seawater electrolysis systems, driven by a vision to play a crucial role in the future energy infrastructure by significantly lowering costs through technological scaling. The market potential for this venture appears strong, as evidenced by CTO Dr. Kazuhiro Takanabe's leadership in the GteX hydrogen electrolysis team, the company's selection for the "Startup Ecosystem Tokyo Consortium" and "Fukushima Tech Create" programs, and its upcoming exhibition at "Asia-Pacific Hydrogen 2025". In a market increasingly demanding low-cost, sustainable hydrogen production, pHydrogen's technology seems poised to contribute significantly to the green hydrogen sector.　 We have high hopes for its future development.
