DOE-funded researchers at Sandia National Laboratories have developed new chemical technology that could lead to batteries able to cost-effectively store three times more energy than today's batteries. The new family of liquid salt electrolytes, called MetILs, might enable economical and reliable incorporation of large-scale intermittent energy sources, like solar and wind, into the nation's electric grid.
The research team is funded by the Department of Energy's Office of Electricity Delivery and Energy Reliability (OE). Imre Gyuk, OE's energy storage systems program manager, notes that the new solution could "lead to innovative, cost-effective storage systems with major impacts on the entire US grid." Better energy storage techniques help even out the fluctuating power flow from renewable sources and improve integration with the grid, which was designed for steady power sources.
