How Batteries Are Reshaping the Global Energy System

As the global energy system adds more intermittent renewables, one fact is becoming increasingly clear: Affordable, large-scale energy storage remains the enabling holy grail for these clean energy sources.  Solar and wind are providing exponentially growing amounts of zero-carbon electricity, but they are still beholden to the weather and the rotation of the Earth. The sun sets and the wind dies down, but the grid must still hum along at perfect balance. That’s where grid-scale battery storage steps in. The reality is that power must…
