EnerDel, ITOCHU Announce Second Smart Grid Battery Storage Project

January 19, 2010 by Jeff Shepard

EnerDel announced that it is partnering with the real estate arm of Japan’s ITOCHU Corp., to develop and produce the advanced battery systems for a residential smart grid energy storage project to be installed in a major apartment building near Tokyo. The system will provide a critical link between renewable energy, high-speed charging for electric cars and the local utility grid.

It is the second such venture between the two companies, following the announcement last month that they are teaming up with Mazda Motor Corp. on a similar system using vehicles converted to electric drive using a platform designed and built by EnerDel and its partner THINK, which will be stationed at a Family Mart convenience store.

"These are the first projects anywhere in the world to bring all the critical elements of a smart, sustainable network that connects renewable energy and transportation in the places where people live and work," said Naoki Ota, Chief Operating Officer for EnerDel. "It will also demonstrate that EnerDel’s lithium-ion battery systems are equally capable, whether it is in a car or a stationary grid application. Our longstanding partnership with ITOCHU has provided the means to set another exciting industry precedent."

"We are delighted to be partnering again with ITOCHU to develop this industry leading project," added Charles Gassenheimer, Chairman and CEO of EnerDel parent company, Ener1. "We are pushing hard to drive pioneering initiatives like this to develop a secondary market for automotive grade lithium-ion batteries. I believe this secondary market will be a key enabler to reducing battery costs for automotive buyers and accelerating the growth of the market for electric powered vehicles."

Sales in the five-story building begin this month, with the first move-ins scheduled for early 2011. Going forward, ITOCHU Property Development, Ltd. aims to introduce the ’secondary use’ system to twenty percent of its new apartment buildings. Secondary use implies a battery that has been redeployed from its primary application, normally an electric vehicle, with significant storage capacity remaining. The residual life in that battery can then be sold into a secondary market application, such as community or residential grid storage. Importantly, a viable battery aftermarket could lower upfront costs for automotive buyers given that the cost of the battery can be spread over its useful life.

The two projects will also gather a continuous stream of long-term performance data on new, stationary battery systems in real time, showcasing system longevity and demonstrating the valuable second life on the grid once battery packs have cycled through their automotive lifecycle, where operating parameters are much more taxing.
