New “Flow” Battery Does that Cheap Energy Storage Thing: Filed under: Energy News

Scientists on the lookout for utility-scale, high efficiency batteries are developing new “flow”systems that that store energy more effectively than lead-acid or lithium-ion batteries, but there’s a catch. The flow batteries in operation now are about the size of a house and they cost more than the equivalent in lithium-ion batteries. The race is on to find smaller, cheaper alternatives and researchers at Sandia National Laboratories believe that they are on to the solution, which is, in fact, a solution of liquid salts called MetILs . The limits of lithium-ion for wind and solar Lithium-ion batteries have been the gold standard of energy storage solutions for a long time, but they fall short when it comes to the utility-scale systems needed to keep up with new high efficiency wind turbines and advanced solar technology . The cost of lithium-ion batteries is one factor. An...
