- New facilities at Kawasaki Works will produce electrolysis cell frames and membranes.
- The project started on December 18, 2024, with support from Japan's GX Supply Chain Development Program.
- Asahi Kasei's medium-term plan includes growth in alkaline water and chlor-alkali electrolysis.
- Kawasaki Works will focus on 'Energy & Infrastructure' businesses after discontinuing certain resin and latex operations.
Project Overview
Asahi Kasei is expanding its Kawasaki Works to manufacture components for electrolysis systems, focusing on alkaline water electrolysis and chlor-alkali electrolysis. This expansion is driven by the anticipated growth in demand for clean hydrogen production.
Strategic Investment
The new facilities will produce electrolysis cell frames and membranes, supporting two key business areas: clean hydrogen production and ion-exchange membrane chlor-alkali electrolysis for chlorine and caustic soda. This investment aims to enhance vertical integration and ensure a stable supply to meet future market demands.
Government Support
Initiated on December 18, 2024, the project has been selected for financial support under the Japanese Ministry of Economy, Trade, and Industry’s “GX Supply Chain Development Program.” This backing will help Asahi Kasei increase production and deliver advanced solutions to the hydrogen, chlorine, and caustic soda markets.
Business Strategy
Under its medium-term management plan, Asahi Kasei has categorized its electrolysis business as having “Growth Potential,” viewing it as a key driver for future growth. This aligns with the company's broader initiative to refine its Material sector through strategic investments and business portfolio transformation.
Site Focus
In May 2025, Asahi Kasei announced the discontinuation of its MMA, CHMA, PMMA resin, and SB latex businesses at Kawasaki Works. Moving forward, the site will focus on managing “Energy & Infrastructure” businesses, integrating expertise in chlor-alkali and alkaline water electrolysis to address both clean hydrogen and basic chemical markets.
