Start of green chemical plant demonstration projectutilizing large-scale hydrogen production system

Asahi Kasei Corporation (“Asahi Kasei”) and JGC Holdings Corporation (“JGC”) have jointly applied for aproject entitled “Large-scale Alkaline Water Electrolysis System Development and Green Chemical Plant
Demonstration” (“the Project”) under the “Green Innovation Fund /Hydrogen Production by Water
Electrolysis Using Renewable Energy” envisioned for fiscal 2021–2030 by Japan’s New Energy andIndustrial Technology Development Organization (“NEDO”), and the Project has been accepted.
1. BackgroundHydrogen is expected to play an important role for achieving a carbon neutral society. Asahi Kasei has
advanced developments to commercialize hydrogen production technology including development of theworld-leading 10 MW large-scale alkaline water electrolysis system at the Fukushima Hydrogen Energy
Research Field (FH2R) as part of a NEDO project1 while JGC has developed ammonia production
technology using CO2-free hydrogen through the Cross-ministerial Strategic Innovation Promotion
Program (SIP)2 led by the Cabinet Office of Japan.
2. Overview of the Project
Asahi Kasei and JGC will work together in the Project to jointly demonstrate the large alkaline waterelectrolysis system on a scale of up to 100 MW3 and the green chemical plant using hydrogen fromrenewable energy, leveraging the hydrogen-related technology both companies have accumulated overan extended period, to enable practical application in society as swiftly and surely as possible.
Demonstration and commercialization of the large alkaline water electrolysis system on a 2-digit MW
scale will utilize feedback from FH2R in constituent technology developments together with module
technology for parallel installation of electrolyzers to meet market needs from the perspectives of safety,durability, performance, and cost.
For the green chemical plant, Asahi Kasei and JGC will jointly develop an integrated control system
which controls the amount of hydrogen supply and optimizes plant operation in the process supplied byhydrogen feedstock originating from fluctuating renewable energy. Feasibility study (FS) andtechnological demonstration will also be performed on plants utilizing the integrated control system forchemical synthesis of products such as green ammonia.
To accelerate commercialization and market creation by elucidating benefits and challenges related topractical application in society, companies involved in the supply chain of green hydrogen and green
chemicals are invited to participate in the Project. In fiscal 2021, Mitsubishi Corporation and JERA Co.,
Inc. are scheduled to join as consigned companies.
