Ultra-Low-Cost Electricity Storage

Back to Electricity

Increasing penetrations of intermittent renewables, such as wind and solar power, on the world’s power grids will require the deployment of growing amounts of energy storage to balance out the momentary, daily, and seasonal power fluctuations of these resources. In order for power grids with large amounts of grid-scale energy storage, solar, and wind power to be cost competitive with more traditional power systems, a wide array of ultra-low cost new transformational energy storage technologies will need to be developed and perfected in the years and decades ahead.
