Asahi Kasei, located in Kawasaki, Japan, has received governmental support to enhance its manufacturing capacity for alkaline water electrolyzers, a crucial step in Japan's journey towards carbon neutrality by 2050. This move aligns with the global trend towards green hydrogen as a cleaner energy alternative. The projected surge in global water electrolyzer capacity to 31 GW by 2030 necessitates an increase in manufacturing capabilities to meet the rising demand for hydrogen production. Japan has a longstanding reputation for advancements in hydrogen technology, with green hydrogen being a key component of its 'Green Transformation (GX)' strategy for carbon neutrality. The 'GX Supply Chain Construction Support Project' exemplifies Japan's commitment to fostering a domestic supply chain for innovative technologies. Asahi Kasei's expansion plans include constructing new plants for cell frames and membranes, with an estimated total investment of ¥35 billion, to bolster its capacity to over 3 GW annually. This strategic move aims to leverage synergies between hydrogen production and the established chlor-alkali electrolysis business, enhancing the company's ability to meet market demands and uncertainties in the evolving hydrogen market.
