Fraunhofer claims "breakthrough" in electricity storage - Renewable Energy Focus

More and more electricity is being generated from variable sources of power, such as solar and wind energy. Powerful electric energy storage devices are necessary to level out corresponding irregularities in the power supply. There are more storage technologies than one may imagine. Batteries are the primary format, but other technologies are being developed . However, in general battery technologies remain a growing option for storing variable renewable energy sources such as wind and solar. Increasing amounts of solar and wind energy have to be stored for use during the night, or for times when there is less wind. Electric batteries are an option, and Redox flow batteries offer an effective way to balance out fluctuations in the supply of renewable energy and thus guarantee its constant availability. The batteries store electrical energy in chemical compounds, the liquid...
