Cheap Battery Can Store Energy for a Rainy Day (Mark Peplow and Nature magazine)
Posted by Orrin Judd at January 9, 2014 7:21 PMPower harvested from the Sun and wind is pouring into electricity grids by the gigawatt. That makes it ever more important to find an efficient and convenient way to store renewable energy for those times when the breeze dies or the skies cloud over."Now we have a good chance of solving that problem," says Michael Aziz, a materials scientist at Harvard University in Cambridge, Massachusetts. His solution is a flow battery that packs a high energy density with no need for the expensive metals found in other models.
