From Seawater to EV Batteries: A New Critical-Minerals Frontier

The world’s oceans contain enormous quantities of magnesium, lithium, and other critical minerals needed for electric vehicles, batteries, and advanced manufacturing. New research is exploring how those materials could be extracted from seawater, potentially through systems integrated with existing desalination plants.

In this episode of TechMobility Topics, I examine how seawater extraction could supplement traditional mining, strengthen domestic supply chains, and reduce dependence on imported materials. The technology still faces questions involving cost, scale, and environmental impact, but it could transform desalination from a process that produces freshwater and concentrated waste into a platform for recovering valuable industrial resources.
