U.S. Department of Energy targets vastly cheaper batteries to clean up the grid

The New York Times    ·    July 14, 2021

The U.S. Department of Energy has announced a new goal to reduce the cost of grid-scale, long-duration energy storage by 90 percent by 2030. MITEI’s Nestor Sepulveda SM ’16 PhD ’20 says, “One big obstacle right now is that there’s no policy requirements for utilities to build long-duration storage.”

'Big storage' is the next big technology in the climate fight

Innovative, low-cost long duration energy storage technologies could make a large impact in a more affordable and reliable energy transition. A new paper in Nature Energy by researchers at MITEI and Princeton University’s Andlinger Center for Energy and Environment evaluates the role and value that these technologies could have in securing a carbon-free electric grid and find that they have the potential to lower electricity prices in a carbon-free system by up to 40%.
