Default Vanadium Redox Batteries (VRBs) Hanover

In the future, the growing amounts of solar and wind energy will need to be stored for dark or low-wind periods. One solution is redox flow batteries that can supply current for up to 2000 households. Several Fraunhofer Institutes are working jointly on these fluid batteries of the future. The researchers will present their large battery installation at the Hannover Messe (April 4-8, 2011).

At the Hanover Fair (Hannover Messe), the researchers will demonstrate the operation of the redox flow battery using a 2-kW plant. Three Fraunhofer institutes are involved in the consortium working to expedite the development of these storage batteries. The process already works reliably, notes Dr. Christian Dtsch, business unit manager for Energy Efficiency Technologies at UMSICHT, one of the participating institutes. The challenge lies in the upscale version, the enlargement of these plants. Redox flow batteries are large-scale vanadium-based liquid batteries in which chemical vanadium bonds alternately pick up and emit electrons along membranes. Because these batteries use only vanadium bonds and not two different fluids at the same time as found in other systems, impurities are eliminated. This makes it possible to build very robust and durable batteries a decisive advantage of this battery technology,emphasizes Dr. Tom Smolinka, in charge of coordinating the work at the Fraunhofer Institute for Solar Energy Systems ISE.

If you have been following Australia's largest Potash resource company REWARD: ASX RWD that rose 44% yesterday, you might be interested to know that Dr M Ruane who is a major shareholder of RWD also holds and is a director of IRC.
