ZBB Energy

ZBB Energy makes and sells energy storage systems designed to store surplus energy for use at times when energy demand is higher than the utility company (or other generator) can provide. Its products -- based on the company's zinc-bromine battery technology -- also provide a source of power protection from voltage, current, or frequency deviations that can cause brownouts or power outages. While ZBB Energy markets its products primarily to utility companies and renewable energy generators in Australia, China, Europe, and North America, it has had only one customer to date, the California Energy Commission. ZBB Energy operates one manufacturing facility in Menomonee Falls, Wisconsin.
