NREL: Longer Duration Battery Storage Can Combat Even More of the Polluting Peak in US
The US National Renewable Energy Laboratory (NREL) has put numbers on the significant potential for energy storage to replace peaking capacity on the grid in the US, albeit with an understanding that as the peak changes, the goalposts will also move. NREL has said in a report just-published that around 70GW of peaking capacity in the US – from a total base of about 261GW – could be served by energy storage systems of four, six and then eight hour durations.
