GM is investing in a California lithium extraction project – TechCrunch


Normal Motors is investing in domestically sourced lithium. The corporate mentioned Friday it turned the primary investor in an Australian firm’s challenge to extract the mineral, a crucial part of electrical car batteries, from the Salton Sea Geothermal Area close to Los Angeles. The automaker could have first rights on lithium produced by Managed Thermal Assets’ “Hell’s Kitchen” lithium extraction challenge.

The Hell’s Kitchen challenge is predicted to start producing lithium in 2024. That output can be utilized in GM’s Ultium battery cells, that are being manufactured as a part of a three way partnership with LG Vitality Answer, after present process validation and testing. Whereas Tim Grewe, GM’s normal director of electrification technique and cell engineering, declined to supply specifics on how a lot lithium GM will seemingly obtain, he mentioned the corporate expects “it’ll be a major quantity of [GM’s] North American lithium.”

GM and different automakers will want a variety of lithium in the event that they wish to meet their electrification targets. For GM, that features transitioning away from inner combustion engines totally by 2035. However that wide-scale transition will even seemingly imply higher competitors – not just for prospects’ {dollars}, however for the supply minerals that compose important components like batteries.

Typically, lithium is produced both by way of arduous rock mining or by extracting the mineral from brine deposits. Each strategies have been criticized for his or her impacts on the setting. What makes CTR’s challenge stand out is that it’s going to use renewable geothermal power – produced from the Salton Sea Geothermal Area, an enormous space within the Imperial Valley that’s already residence to eleven geothermal energy stations – to course of the lithium.

Along with being powered by renewable power, CTR says the challenge makes use of a closed-loop direct extraction course of that returns spent brine to its underground supply and leaves no manufacturing tailings, a type of waste reside from mining.

Many of the world’s lithium is sourced from a small variety of international locations, predominately Chile, Australia, China and Argentina. There just one lithium manufacturing web site in america, a brine operation in Nevada owned by chemical manufacturing big Albemarle. However there’s been an elevated deal with boosting home manufacturing within the mineral lately, pushed largely by two traits: the anticipated demand for the mineral, which is predicted to quickly enhance due partly to the transition to battery electrical autos; and a bipartisan deal with preserving the US aggressive in rising applied sciences.

In accordance with the California Vitality Fee, as a lot as one third of the world’s present demand for lithium may very well be discovered within the state’s lithium deposits. The CTR challenge is certainly one of many aimed toward extracting lithium from the Salton Sea’s huge brine fields.
