Huge Redox-flow-storage based on vanadium, close to Karlsruhe in Germany, to work after March 2017. 19 millions Euro used by Fraunhofer Institut for Chemical Technology. Due to the leader of the project, Peter Fischer, they try to make the storage more reasonable in the future. He claims this storage might supply an entire village with energy for around 10 hours. (Dr. von Werz: I do live in a village, what does he mean with these words? My village has 185 adults… ). When they wanted to build up a big wind energy tower close to the project, during the transport one of the big parts had a crash with a bridge.
