The “world’s first” large-scale energy storage system made from used electric vehicle batteries has been developed in Japan.

The 600KW system consists of 16 used batteries and will be used for three years to monitor fluctuations in electricity generated by a solar farm in Osaka.

The project, built by Sumitomo Corporation, is part of a test under Japan’s Ministry of the Environment (MoE) to expand the development of renewable resources.

Norihiko Nonaka, Battery Business Development Department General Manager said: “We are pleased to be a part of such an important verification project that can both utilise used EV batteries and provide a large-scale power storage facility, which are important issues that need to be addressed for the future of renewable energy.”

The storage system is scheduled for operation later this month.
