Toyota and Chiyoda agree to develop large-scale electrolysis system

Japanese companies Toyota and Chiyoda have teamed up to jointly develop a large-scale electrolysis system with an aim of achieving the government targets for the introduction of electrolysis equipment both in Japan and overseas as part of the  Basic Strategy on Hydrogen.

To this end, the two companies have formed a strategic partnership and signed a basic cooperation agreement.

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, Toyota explained.

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

Under the basic cooperation agreement, the introduction of an electrolysis system in the Hydrogen Park at the Toyota Honsha Plant will start in 2025. It will be expanded in the future to the 10 MW class and used for verification and development.

Recently, Chiyoda Corporation signed a joint venture agreement with Kawasaki Heavy Industries, Toyo Engineering Corporation, and JGC Corporation to enhance the front-end engineering design (FEED) execution for a liquefied hydrogen supply chain in development by Japan Suiso Energy (JSE).
