Japan has inaugurated its largest green hydrogen production facility in Hokuto City, Yamanashi Prefecture—a ¥18.6 billion ($122 million) project that could redefine the role of hydrogen in industrial decarbonization.
The Green Hydrogen Park Hakushu, developed by the Yamanashi government alongside ten major corporate partners including Suntory Holdings, Toray, Tokyo Electric Power Company Holdings (TEPCO), Canadavia, Siemens Energy, and Miura, marks a critical evolution in Japan’s clean energy transition.
With a 16MW capacity, the Green Hydrogen Park Hakushu has begun supplying renewable hydrogen through a dedicated two-kilometer pipeline to Suntory’s Minami Alps Hakushu Mineral Water Plant and Hakushu Distillery. The hydrogen fuels low-NOx boilers and supports key production processes—such as steam sterilization and whisky distillation—replacing fossil fuels with carbon-free energy sources.
At full capacity, the facility will produce approximately 2,200 tonnes of hydrogen annually, offsetting around 16,000 tonnes of CO₂ emissions per year. The initiative demonstrates the feasibility of integrating large-scale hydrogen systems into industrial operations, particularly in sectors such as food and beverage manufacturing, where continuous heat and steam are essential.
The project’s technological backbone relies on polymer electrolyte membrane (PEM) electrolysers supplied by Siemens Energy and Canadavia. Installed in dual production halls, the systems convert renewable electricity—sourced primarily from solar power—into hydrogen with high efficiency and flexibility.
The project’s funding stems from Japan’s New Energy and Industrial Technology Development Organization (NEDO) under its Green Innovation Fund Program, reflecting the government’s commitment to scale hydrogen beyond pilot projects. The facility is also designed to act as a regional supply hub, potentially exporting hydrogen to the Tokyo metropolitan area, strengthening both industrial resilience and regional energy security.
Project partners including Toray, TEPCO, and Miura are engaged in a multi-year research effort to enhance system reliability and cost-effectiveness. Operational data collected through 2026 will inform strategies for performance optimization, maintenance efficiency, and storage management. The results are expected to shape Japan’s broader hydrogen rollout strategy and support the creation of exportable technology standards.
This research focus underscores a key challenge for hydrogen’s scalability: cost reduction. While Japan’s technological leadership in electrolyser design and materials science is strong, commercial viability remains limited without continued public investment and clear market signals. The consortium’s data-driven approach seeks to close that gap, demonstrating that hydrogen can become both an environmental and economic asset for heavy industry.
A central ambition of the Hakushu project is to establish a fully circular hydrogen energy system by 2026. The facility integrates solar power, electrolysis, hydrogen storage, and combustion for industrial heat—creating a self-contained, zero-carbon supply chain. By achieving a renewable-to-hydrogen-to-heat cycle, the project aims to prove that local, decentralized hydrogen systems can operate independently of fossil fuels.
For Suntory, the initiative supports corporate sustainability targets while reducing exposure to volatile fossil energy markets. For Japan, it offers a replicable model for industries dependent on heat-intensive processes—demonstrating how hydrogen can be embedded into production lines without disrupting efficiency or output.
