TOKYO, Feb. 7, 2014 /PRNewswire/ --Sumitomo Corporation (Head Office:
Chuo-ku, Tokyo; President and CEO: Kuniharu Nakamura) has developed and
installed the world's first large-scale power storage system which utilizes
used batteries collected from electric vehicles (hereinafter : EV). This
commercial scale storage system, built on Yume-shima Island, Osaka, will begin
operating in February 2014.

First Large-Scale Power Storage System Made from Reused EV Batteries

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 safely and
effectively utilizing the huge quantities of discarded used EV batteries which
will become available in the future. This project has been selected as a model
project for "Verification of the battery storage control to promote renewable
energy" for the fiscal year 2013 by the Ministry of the Environment of Japan.

Sumitomo Corporation created the joint venture company, "4R Energy
Corporation", in collaboration with Nissan Motor Co., Ltd. in September 2010,
to address the secondary use of EV lithium-ion batteries. The used EV
batteries that will be recycled into this large-scale storage system have been
recovered and have gone through thorough inspection and maintenance at 4R, to
confirm safety and performance. This prototype system (600kW/400kWh) consists
of sixteen used EV batteries.

Battery Business Development Department General Manager, Norihiko Nonaka said,
"We are pleased to be a part of such an important verification project that
can both utilize 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."

Sumitomo will seek new business opportunities which can make use of the highly
economical storage system, as well as work on developing new applications for
used EV batteries. The company aims to actively promote this approach, which
can both contribute to expanding the use of EV and encourage the use of
renewable energy. Sumitomo is committed to the movement toward lowering the
carbon footprint of a sustainable society.
