Solar storage from used EV batteries set for testing in Japan

The worlds first large-scale solar power storage system to incorporate used batteries from electric vehicles has been built in Japan.
The commercial-scale energy storage system has been developed and deployed at a 10MW solar farm in south western Japan, having been selected by Japans Ministry of Environment as a model project to test the use of battery storage in conjunction with renewable energy.
The Hikari-no-Mori (Forest of Light) solar farm was built by Sumitomo Corporation and six associate companies, when their mega-solar proposal won the city of Osakas 2010 public tender for ideas on a new use for a landfill site located on Yume-Shima Island, Osaka.
Sumitomo then created a joint venture company with Nissan Motors 4R Energy Corporation to investigate the re-purposing of used EV batteries. This led to the development and installation of a 600kw/400kWh prototype system, using sixteen used lithium-ion batteries from Nissans Leaf model EV.
The idea that the used battery from a hybrid or electrical car can be re-used for such purposes as the storage of renewable energy is an exciting one for the industry...
