New lithium technology can help the world go green — if it works

April 7 (Reuters) – Rio Tinto, Basic Motors and even the U.S. Vitality Division are investing closely in a crop of newer applied sciences that might revolutionize the best way lithium is produced for electrical automobile batteries.

Now these applied sciences simply must show they work on a industrial scale.

In the event that they do, miners will have the ability to enhance international lithium manufacturing with a footprint far smaller than open-pit mines and evaporation ponds, which frequently are the dimensions of a number of soccer fields and unpopular with native communities.

These so-called direct lithium extraction (DLE) applied sciences extract the white metallic from brine utilizing filters, membranes, ceramic beads or different gear that may sometimes be housed in a small warehouse. However they typically use a number of potable water and electrical energy, and none have labored at industrial scale.

International automakers, mining firms and buyers are pouring tens of millions of {dollars} into DLE firms, betting they will provide the majority of the lithium wanted to energy the electrical automobile revolution.

“It is such a recreation changer. There’s large alternatives,” U.S. Vitality Secretary Jennifer Granholm informed an vitality convention final month about DLE.

Granholm’s division has given Warren Buffett’s Berkshire Hathaway Inc (BRKa.N) a $15 million grant to check DLE expertise at California’s Salton Sea, beneath which sit massive geothermal lithium deposits, and is contemplating funding different DLE initiatives.

DLE applied sciences would problem conventional miners similar to Albemarle Corp (ALB.N), the world’s largest lithium producer, and potential miners similar to Lithium Americas Corp (LAC.TO), ioneer Ltd (INR.AX) and Piedmont Lithium Inc (PLL.O).

Albemarle is finding out varied DLE applied sciences however its executives have mentioned DLE seemingly works greatest when engineered for a selected lithium deposit, which may curb enthusiasm.

Giant water utilization by a number of varieties of DLE applied sciences has raised eyebrows. The expertise Basic Motors Co (GM.N) is counting on to produce a “sizeable quantity” of its lithium from the Salton Sea area makes use of 10 tonnes of water for each tonne of lithium produced.

Privately held Lilac Options Inc, backed by BMW (BMWG.DE) and Invoice Gates’ Breakthrough Vitality Ventures, developed that expertise and mentioned it may use a desalination plant to filter brackish water to keep away from utilizing potable water.

“If wanted, we’re prepared to make these capital investments to make sure we’re not jeopardizing anybody’s freshwater,” mentioned Lilac CEO Dave Snydacker. “New expertise is totally important for society to acquire the volumes of lithium which can be needed for electrical autos.”

Outstanding quick vendor Hindenburg Analysis issued a 59-page report in February questioning whether or not the DLE expertise from Normal Lithium Ltd (SLI.V) even works, regardless of backing for its Arkansas challenge from chemical giants Koch Industries Inc and Lanxess AG (LXSG.DE).

“DLE is a kind of applied sciences that is been a hope and a prayer, Hail Mary for many, in order that’s fertile floor for inventory promoters,” mentioned Nathan Anderson of Hindenburg.

Normal disputed the allegations within the report, which erased greater than $300 million in Normal’s market worth in someday and stoked fears in regards to the DLE motion. The inventory has partially recovered.


There are dozens of DLE-focused firms worldwide, some with their very own applied sciences, some with brine-rich acreage and a few with each.

“Direct lithium extraction is changing into a scorching topic,” mentioned Olivier Le Peuch, chief government of Schlumberger Inc (SLB.N), which is creating DLE expertise with Panasonic Corp (6752.T). It hopes to produce Tesla’s (TSLA.O) Nevada Gigafactory, however has acknowledged it should discover a approach to produce the metallic with out potable water.

U.S. and international ambitions to go inexperienced are at stake. Not less than 70% of the U.S. lithium deposits are held in brine reserves, in response to the Vitality Division. Elsewhere, DLE presents an opportunity to supply lithium in areas the place open-pit mines face robust opposition.

In Germany, Vulcan Vitality Assets Ltd (VUL.AX) goals to make use of DLE the produce the metallic for Renault SA (RENA.PA) and different automakers from Germany’s Black Forest.

“Because the EV transition accelerates, we will develop with that market,” mentioned Horst Kreuter, Vulcan’s CEO.

Privately held Luna Lithium Ltd plans to make use of DLE in Nevada, CEO Emily Hersh mentioned. In Utah’s Nice Salt Lake, Compass Minerals Worldwide Inc (CMP.N) has been making an attempt to selected a DLE expertise for greater than a 12 months and hopes to decide this summer season.

Galvanic Vitality LLC goals to promote to promote the 100,000 brine-rich acres it controls in Arkansas if it finds a DLE expertise that works.

“These firms promote and speak about what they will do, however I am a skeptic till confirmed in any other case,” mentioned Brent Wilson, a former Chesapeake Vitality Corp (CHK.O) geologist who fashioned Galvanic in 2018.

Rio Tinto Ltd (RIO.AX)(RIO.L) paid $825 million final December for an Argentina DLE challenge, which it mentioned “has the potential to considerably improve lithium recoveries as in comparison with photo voltaic evaporation ponds.”

Privately held Vitality Exploration Applied sciences Inc, generally known as EnergyX, has developed a DLE expertise that makes use of membranes to filter lithium, however in some circumstances, EnergyX’s DLE membrane expertise might must be paired with one other DLE expertise, mentioned CEO Teague Egan.

“Our DLE membrane expertise is excellent, however DLE does not must imply one expertise or one other. I believe that is what individuals fail to spot,” mentioned Egan, who goals to take EnergyX public by mid-2023.

EnergyX just lately despatched a pilot model of its expertise to Bolivia within the hopes of convincing La Paz to selected it to develop the Uyuni salt flat, one of many world’s largest lithium deposits.

Lilac, in addition to a number of Chinese language and Russian firms, are additionally competing for the Bolivian challenge, pointing to the rising international consideration paid to the trade.

“DLE will not be a magic wand, however it’s a very precious instrument within the toolkit,” mentioned Luna Lithium’s Hersh.
