Giant wind power battery begins operation
A large new battery capable of storing 20 megawatt hours of its integrated wind power turbine has started operating on the premises of the Fraunhofer ICT research institute near Karlsruhe, the Heilbronner Stimme reports. The so-called redox-flow-battery, which costs 19 million euros, can store enough power to supply a small village for ten hours, the article says.
In a press release, Fraunhofer ICT says “redox-flow batteries are efficient (>75%), safe, and have a longer service life than conventional batteries such as lithium ion.”
