Metal-Free 'Rhubarb' Battery Could Store #Renewable Grid #Energy

A molecule nearly identical to one in rhubarb may hold the key to the future of renewable energy. Researchers have used the compound to create a high-performance 'flow' battery, a leading contender for storing renewable power in the electric utility grid. If the battery prototype can be scaled up, it could help utilities deliver renewable energy when the wind is calm and the sun isn't shining.Abstract. Shared via feedly // published on Slashdot // visit site
