NREL says energy storage will likely become a key piece of a future U.S. power grid

In the reference case of a new report, NREL suggests battery deployments in the U.S. will boost storage capacity to 200GW and 1200GWh in 2050.

The “Storage Futures Study” concludes that lithium-ion batteries will continue to have the highest market share “for some time,” as system costs for 4-hour storage, including all system components and installation, fall to $200 per kWh capacity by 2030.

Across all modelled scenarios, NREL found diurnal storage deployment could range from 130 gigawatts to 680 gigawatts in 2050, which is enough to support the renewable generation of 80% or higher.
