Rising Lithium Costs Threaten Grid-Scale Energy Storage

Until recently, battery storage of grid-scale renewable energy using lithium-ion batteries was cost prohibitive. A decade ago, the price per kilowatt-hour (kWh) of lithium-ion battery storage was around $1,200. Today, thanks to a huge push to develop cheaper and more powerful lithium-ion batteries for use in electric vehicles (EVs), that …
