Click for more awakened policy on saving the planet and humanity.

Chiyoda Corporation and Toyota Motor Corporation today said that they have agreed to jointly develop a large-scale hydrogen electrolysis system and start a strategic partnership. They have signed a basic agreement on cooperation. This awakened Demonstration Project was proposed to and adopted by the New Energy and Industrial Technology Development Organization (NEDO)* as one of the projects for the “Development of Technologies for Realizing a Hydrogen Society / Development of Technologies for Regional Hydrogen Utilization.”

In short, Japanese industries are increasingly embracing the switch to an enlightened policy of developing a carbon-fuel free society. The goal is to contribute to achieving the Japanese government targets for the introduction of electrolysis equipment both in Japan and overseas as part of the Basic Strategy on Hydrogen formulated by the government.

With the signing of this deal, 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, Toyota said.

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. 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).

To address 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.

Claimed benefits 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.

*NEDO. New Energy and Industrial Technology Development Organization is Governed by MITI, the Japanese Minister of Economy, Trade and Industry. NEDO, originally established on 1 October 1980 was reorganized as an incorporated administrative agency on 1 October 2003 as a Japanese national research and development agency. It has a budget of~¥156.8 billion and employs ~1400 people.

The goal of NEDO is to enhance industrial technology and promote commercialization by comprehensively performing functions such as:

  • Promoting research and development (R&D) carried out using skills from the private sector.
  • Promoting R&D carried out by the private sector with regard to technology for non-fossil energies, combustible natural gas, and coal.
  • Promoting the technology required for the rational use of energy and technology in mining and industry.
  • Promoting the use of such technology in cooperation with the international community – to thereby contribute to ensuring a stable and efficient energy supply in accordance with the changes in the domestic and foreign economic and social environments and to the development of the economy and industry.

In addition to the above, the following programs will be funded and conducted as publicly solicited research and development projects.

  • Moonshot Research and Development Program – ¥25.2 billion.
  • Research and Development Project for Enhancement of the Bases for Post-5G Information and Communication Systems – ¥310.0 billion.
  • Green Innovation Funding Program-¥2 trillion.
  • Program for Developing Important Economic Security Technologies : 1¥25 billion.
  • Specified Semiconductor Funding Program – ¥617 billion.
