could again be part of a revolution — even if by name only — thanks to researchers in the nation’s capital.

That’s because a team at The George Washington University, collaborating with experts elsewhere, claimed to have developed an innovative process to capture lithium. That’s the crucial element in batteries that power electric vehicles and other tech needed for the cleaner energy shift.

Details about the findings, highlighted in a news release and in the journal

, are captivating because the breakthrough is sans invasive mining and harmful chemicals soaking in vast brine pits. The typical extraction methods can be harmful to the environment, as

Instead, GW’s team developed an electro-driven method using a “special material that selectively captures lithium ions from the brine.” It is eventually turned into lithium hydroxide that can be used in EV power packs. What’s more, the cleaner technique can be completed at a “competitive cost,”

that about 600,000 tons of lithium could be extracted from the sea annually, “far exceeding” the nation’s yearly needs.

The innovation could open the door for an abundant domestic supply of the material, which is currently dominated by foreign markets,

The GW innovation includes a complicated-sounding setup called an “intercalation deionization cell,” a production well, an injection well, and other tech. Hot brine is pumped to the surface, and byproduct steam can power a turbine to make electricity. The cooled brine, typically a geothermal industry waste stream, is where the lithium is harvested. The other briny elements are pumped back underground. The converted lithium hydroxide is turned into a powder for battery makers, all
