Chiyoda Corporation and Toyota Jointly Developing Large-scale Electrolysis System

Chiyoda Corporation (hereinafter “Chiyoda”) and Toyota Motor Corporation (hereinafter “Toyota”) have agreed to jointly develop a large-scale electrolysis system and construct a strategic partnership and have signed a basic agreement on cooperation.

The goal is to contribute to achieving the government targets*1 for the introduction of electrolysis equipment both in Japan and overseas as part of the Basic Strategy on Hydrogen formulated by the government.

*1The government targets for the introduction of electrolysis equipment are set at about 10% (approx. 15 GW) of the share of Japan-based companies (including parts manufacturers) within the 134 GW forecast for introduction globally by 2030. (Source: IEA, Global Hydrogen Review 2022)

The production and mass production technologies for electrolysis cell stacks using the fuel cell technology held by Toyota and the processing plant design technologies and large-scale plant construction technologies held by Chiyoda will be brought together to develop a large-scale electrolysis system that can be competitive. This will allow adaptation to the rapidly expanding hydrogen production markets both inside and outside Japan.

Specifically, the goal is to develop an electrolysis system with high hydrogen production efficiency while being the world’s smallest in size.

To be able to respond to the various needs of customers, such as the amount of hydrogen used or limitations on plant floor area, 5 MW-class equipment will be used as the basic unit (floor area: 2.5 m x 6 m, hydrogen production capacity: approx. 100 kg/hr) for development, and will be combined to create a standard package, allowing the construction of large-scale electrolysis systems.

The merits of this equipment include the fact that it only takes up about half the floor area of conventional equipment and offers ease of maintenance while allowing easier shipping, shortened on-site construction times, and lower civil engineering and construction costs. Toyota’s particular expertise in industrial products and Chiyoda’s particular expertise in plant engineering will be combined and optimized, allowing benefits such as lower costs, increased production efficiency, and more stable quality for the electrolysis systems required to produce green hydrogen.

With the signing of this basic agreement on cooperation, the introduction of an electrolysis system in Hydrogen Park at the Toyota Honsha Plant will start in FY2025. It will be expanded in the future to the 10 MW class and used for verification and development. Any further developments will be released as they happen.

Both companies will exhibit at the H2&FC EXPO (organized by RX Japan Ltd., held from Feb. 28 to Mar. 1, 2024) held at Tokyo Big Sight (Koto-ku, Tokyo).

Toyota will continue working on “Producing Happiness for All” with the aim of achieving a hydrogen-based society through a multi-pathway approach in the value chain of “Produce / Transport / Store / Use” which aims for the social implementation of hydrogen.

Beyond Zero

“Achieving zero, and adding new value beyond it”

As part of efforts to pass our beautiful “Home Planet” to the next generation, Toyota has identified and is helping to solve issues faced by individuals and overall society, which Toyota calls “Achieving Zero,” hoping to help reduce the negative impacts caused by these issues to people and the environment to zero. Additionally, Toyota is also looking “Beyond Zero” to create and provide greater value by continuing to diligently seek ways to improve lives and society for the future.
