The new facilities will produce electrolysis cell frames and membranes supporting two core business areas: alkaline water electrolysis systems for clean hydrogen production, and ion-exchange membrane chlor-alkali electrolysis used to manufacture chlorine and caustic soda. This investment strengthens Asahi Kasei’s vertical integration across key materials in the hydrogen and chlor-alkali markets, ensuring a stable supply and readiness to meet future demand.
Under its medium-term management plan, Asahi Kasei has positioned its alkaline water electrolysis and chlor-alkali electrolysis businesses within the “Growth Potential” category, identifying them as key drivers of future expansion. This initiative forms part of a broader strategy to refine the Materials sector and advance the company’s business portfolio transformation.
In May 2025, Asahi Kasei announced the discontinuation of its MMA, CHMA, PMMA resin, and SB latex operations at the Kawasaki Works. Going forward, the site will serve as a central base for the company’s Energy & Infrastructure businesses.
“These new facilities integrate our long-standing expertise in chlor-alkali electrolysis with our growing capabilities in alkaline water electrolysis, enabling us to respond robustly and flexibly to both the clean hydrogen and basic chemical markets,” said Kenji Takeda, Executive Officer of Asahi Kasei for Ion-Exchange Membranes, Microza & Water Processing, and Green Solution Project Business Development. “We will continue to maximize efficiencies between these key businesses, striving to become a core player in the GX supply chain through stable supply, technological innovation, and long-term strategic growth.”
