A great E&E News report looks at how salty wastewater from oil and gas drilling is being eyed as a source of lithium, a mineral critical to batteries in EVs and energy storage.

At the risk of sounding cliched, no stone should be left unturned to find domestic sources of lithium. The U.S. also needs more facilities to refine the mineral for use.
