Stanford researcher Yi Cui and his team say they have designed a new flow battery that will make it easier for solar and wind energy to power the grid, especially since their combined contributions to the grid nears the 20 percent mark.
The problem with the grid at present is that it is unable to adapt to huge variations in power provided by intermittent renewable sources. Flow batteries already counter that problem, but Stanford’s new flow battery will be cheaper and is less of a maintenance hassle.
The new battery does away with the membrane in current models, which is usually composed of expensive metals. Their battery can also last about 5.5 years with daily cycles, and that’s just results from preliminary lab tests.
