Weird Reality

The intermittent supply of green electricity requires large-scale storage to keep our power grids stable. Since normal batteries do not scale very well, the idea of using flow batteries, which store electricity in a fluid is attractive. However, these batteries contain rare metals and are expensive. Scientists at the University of Groningen, the Netherlands, have designed a flow battery electrolyte that may solve both problems. Their results were published in the Journal of the American Chemical...
