Sumitomo Sets Up World's First Large-Scale Power Storage System with Used Batteries

Sumitomo developed and installed the world's first large-scale power storage system that utilizes used batteries collected from electric vehicles. This commercial scale storage system, built on Yume-shima Island, Osaka, began operating in February 2014. Over the next three years, the system will measure the smoothing effect of energy output fluctuation from the nearby Hikari-no-mori solar farm, and will aim to establish a large-scale power storage technology by utilizing the huge quantities of discarded used EV batteries.
