Researchers from the US Energy Department’s SLAC National Accelerator Laboratory and Stanford University have designed what they say is a low-cost, long-life “flow” battery that could enable solar and wind energy to become major suppliers to the electrical grid.

The research, led by Yi Cui, a Stanford associate professor, is a product of the new Joint Center for Energy Storage Research (JCESR), a DOE Energy Innovation Hub.

Led by Argonne National Laboratory, with SLAC as major partner, JCESR is one of five such Hubs created by the Department to accelerate energy research and was established last November.

While solar and wind make a substantial contribution to the nation’s energy supply, they also create significant power fluctuations, which can sometimes exceed the tolerances of the electrical grid.
