Some lithium could come from wastewater
Water from Marcellus shale gas wells could supply up to 40% of U.S. demand for the metal, according to a new Pitt study.
Most batteries used in technology like smart watches and electric cars are made with lithium that travels across the world before even getting to manufacturers. A new analysis using compliance data from the Pennsylvania Department of Environmental Protection suggests that if it could be extracted with complete efficiency, lithium from the wastewater of Marcellus shale gas wells could supply up to 40% of the country’s demand. Already, researchers in the lab can extract lithium from water with more than 90% efficiency according to Justin Mackey, a researcher at the National Energy Technology Laboratory and PhD student in the lab of Daniel Bain, associate professor of geology and environmental sciences in the Kenneth P. Dietrich School of Arts and Sciences.
