SILVER PEAK, NV — On the sting of Western Nevada, hours from a serious metropolis and miles down personal filth roads, lies the USA’ solely lithium-producing plant.
The closest city is Tonopah – inhabitants 2,179 – the place a prospector found silver on the flip of the 20th century. The city’s mining roots are nonetheless on show, however the motion has shifted to the nation’s largest lithium brine operation 45 minutes away.
Silver Peak has been producing lithium for the reason that Sixties. Specialty chemical substances firm Albemarle acquired the positioning in 2015 from Foot Mineral Firm, and has owned it ever since.
Silver Peak has gained newfound consideration in recent times because the power and transportation sectors race to wean themselves off climate-warming fossil fuels. Lithium’s distinctive properties make it the frequent denominator throughout battery applied sciences. Forecasts for simply how a lot can be wanted within the a long time to return varies. Below the Worldwide Power Company’s most formidable local weather situation, lithium provide must develop 40-fold by 2040 from immediately’s ranges.
The U.S. was a frontrunner in lithium manufacturing, however it’s since ceded that place to international nations, together with China. Now the Biden Administration has mentioned that bringing battery provide chains again to U.S. shores is a matter of nationwide significance, and the not too long ago handed Inflation Discount Act – the biggest local weather package deal in U.S. historical past – underscores this new push in the direction of home manufacturing of significant supplies.
A part of the difficulty with bringing new provide on-line, nonetheless, is the sheer quantity of land required. The dimensions of Silver Peak is difficult to know from picturs. It spans 13,000 acres, and appears to seem out of nowhere, tucked between mountain ranges within the Nevada desert.

The solar bears down and it hardly rains – superb situations for the sort of lithium extraction, which is dependent upon photo voltaic evaporation. There’s additionally salt, a byproduct of manufacturing, in every single place.
The massive website will not be bustling with exercise, which makes it appear even bigger than it’s. The solar offers a lot of the labor, and fewer than 80 individuals whole work on the facility. However it’s websites like these – huge, sweeping operations – that can energy the longer term.
“The U.S. is initially of actually increasing and growing its provide chain domestically for this vital mineral lithium, in addition to the broader provide chain for electrical autos and electrification,” mentioned Karen Narwold, govt vice chairman and chief administrative officer at Albemarle.
“From Albemarle’s perspective, we predict the USA can deliver the total provide chain right here.”
From lots of of toes underground…to your automotive
Lithium could be produced from brine, onerous rock or clay, and every methodology requires its personal set of situations and extraction processes. Silver Peak produces lithium from brine tapped from the Clayton Valley basin.
Salty brine that comprises lithium is pumped from between 300 and a pair of,000 toes underground to the floor. Then, over the course of 18 to 24 months, photo voltaic evaporation concentrates the lithium.
This is likely one of the first of 23 ponds that lithium-rich brine travels by means of over the course of 24 months at Albemarle’s Silver Peak website. Brine is pumped from as a lot as 2,000 toes underground to the floor.

The brine flows by means of a sequence of 23 ponds on the website because it turns into extra concentrated, taking over an more and more vivid turquoise shade. The ponds vary in dimension, and the biggest is larger than 700 soccer fields. As extra brine is evaporated, the ponds get smaller and smaller.
About midway by means of the method, lime is pumped by means of the brine, which separates out magnesium that is discovered alongside the lithium. As soon as the brine has moved by means of all 23 ponds, the remaining lithium is chemically processed right into a white powder type often called lithium carbonate.
What occurs subsequent is dependent upon the lithium’s finish use. Lithium is not solely utilized in batteries, however can be present in prescription drugs and glass, amongst different issues. A number of the carbonate from Silver Peak is shipped to Albemarle’s processing facility in Kings Mountain, North Carolina. There it may be additional refined into lithium hydroxide, which is used for electrical automobile batteries. Albemarle counts main automakers, together with Tesla, as clients.
Lithium costs skyrocket
Lithium has garnered important consideration in current months as a result of a pointy value spike, surging greater than 700% since January 2021, in line with Benchmark Mineral Intelligence. In some locations, together with the Chinese language spot market, costs are up much more.
In a boom-and-bust cycle of kinds that mirrors different commodity markets, costs rose over the course of 2017 and into 2018 earlier than cratering midway by means of the 12 months and falling all through 2019. At that time the market was oversupplied, which led to a scarcity of funding in new manufacturing. The consequences of that slowdown are nonetheless being felt. Right this moment, provide is racing to meet up with demand, and a few are warning that it merely will not.
Based on forecasts from Benchmark, 600,000 tons of lithium carbonate equal can be mined this 12 months — that is 10,000 tons lower than wanted. By the top of the last decade, the agency envisions annual provide reaching 2.15 million tons of LCE, which can lag demand by a whopping 150,000 tons.

The surge in lithium demand comes from international locations and corporations doubling down on local weather targets prior to now few years. That features automakers, that are saying formidable all-electric fleets.
Lithium is not the one mineral in these batteries — additionally they require cobalt, graphite and nickel. Every has its personal limitations, and scientists are experimenting with totally different battery chemistries.
However whereas it is potential to swap out some supplies, at this level there is not any viable different to lithium.
Though lithium will not be a scarce useful resource, getting a brand new mine up and working can take about seven years. These initiatives are capital intensive and require many permits, all of which suggests the business is sluggish shifting.
Lithium Americas has been attempting for greater than a decade to get manufacturing going at its Thacker Go clay mine in Nevada, towards opposition from environmentalists and Native American tribes. Piedmont Lithium is within the means of growing a spodumene mine in North Carolina, which it hopes will start producing by 2026.
Albemarle is working by itself North Carolina mine at Kings Mountain. It is a brownfield mine – which means it was beforehand producing – which the corporate hopes will assist it pace previous the hurdles that delay new initiatives. Albemarle additionally has processing services within the state.
Extractive industries are resource-intensive by their very nature and could be extremely disruptive to native ecosystems. However it’s onerous to see how the world can transfer away from fossil fuels with out new lithium manufacturing. An electrical automobile requires greater than six occasions as many mineral inputs relative to inside combustion autos, in line with the IEA. Below the Paris-based company’s most formidable local weather situation, it forecasts 230 million electrical vehicles, buses, vans and heavy vehicles on the street by 2030.
That is the final of the 23 evaporation ponds at Albemarle’s Silver Peak lithium website. From right here, the lithium is shipped for on-site processing the place it is changed into lithium carbonate.

Nonetheless, some imagine these forecasts are far too formidable, and the world ought to as an alternative deal with present sources slightly than growing new websites.
Recycling might additionally change into an possibility – Albemarle is likely one of the corporations engaged on this – however the market hasn’t but reached vital mass. Applied sciences are additionally being developed to make operations extra environment friendly in order that mines yield as a lot as potential.
Albemarle units its sights on growth
Silver Peak is Albemarle’s largest U.S. lithium manufacturing website at current, however it constitutes solely a small portion of the corporate’s general lithium manufacturing. Silver Peak produces about 5,000 metric tons per 12 months of lithium carbonate equal (LCE), whereas Albemarle’s Chile operation – within the Salar de Atacama area – has the capability to supply 85,000 metric tons per 12 months. The operation there makes use of the identical brine manufacturing course of that was first developed in Nevada.
The corporate additionally co-owns two mines in Australia, and operates quite a few processing services, together with in China.
Albemarle can be rising its footprint at Silver Peak. In Jan. 2021 the corporate introduced plans to double capability to 10,000 metric tons a 12 months, which the corporate mentioned is sufficient to energy round 160,000 electrical autos.

Albemarle’s Narwold mentioned the growth, initially slated for completion in 2025, is forward of schedule. The corporate spent the final 12 months and a half establishing 22 new brine-pumping wells, finishing the primary stage of the growth.
By the top of this 12 months Albemarle can be pumping at 20,000 acre toes yearly, which is equal to roughly 18.5 million gallons of water per day. That represents the total extent of Albemarle’s water rights, which can be the whole thing of the rights obtainable within the Clayton Valley.
Albemarle isn’t just a lithium firm: it additionally has bromine and chemical substances divisions. However the lithium section has grown in significance following the worth spike and Albemarle’s growth plans. Lithium now accounts for about two thirds of the corporate’s income, in line with Meredith Bandy, vice chairman of investor relations and sustainability at Albemarle. That is up from a number of years in the past, when every division was about one third of general income.
“We have been investing within the lithium marketplace for the final couple of years, and that is beginning to repay by way of volumetric progress in addition to value efficiency,” she mentioned.
Historically Albemarle had long-term, fastened contracts with clients. However this 12 months the corporate restructured a few of these contracts in an effort to seize upside from rising costs. It appears to be paying off.

Throughout the second quarter, Albemarle mentioned internet gross sales from its lithium division jumped 178% 12 months over 12 months. The corporate raised its full-year steerage 3 times between Could and August, when Albemarle posted second-quarter outcomes. The corporate will report third-quarter earnings on November 2.
For the total 12 months, Albemarle now expects adjusted EBITDA for its lithium division to develop between 500% and 550% on a year-over-year foundation. That is up from prior expectations of a 300% soar.
“There is a large quantity of demand. The business actually is having to work onerous – Albemarle is having to work onerous – to maintain up with that demand,” mentioned Bandy.
Traders have rewarded the corporate’s efficiency. The inventory climbed to an all-time excessive on September 14, throughout a rocky interval within the broader market. Shares have since fallen 18%, however the inventory continues to be up about 8% for the 12 months, with an organization valuation round $30 billion.
By comparability the S&P 500 and Nasdaq Composite are down 25% and 33%, respectively, for 2022.
Local weather invoice: a recreation changer?
Whereas the overwhelming majority of battery manufacturing takes place exterior the U.S. — China is a key participant, at the moment refining 56.5% of worldwide lithium, in line with Benchmark — the Biden Administration is attempting to vary that.
In February, the White Home introduced funding for home manufacturing of supplies and minerals vital to the power transition. Then, in March, Biden invoked the Protection Manufacturing Act for these supplies.

“To advertise the nationwide protection, the USA should safe a dependable and sustainable provide of such strategic and demanding supplies,” a March assertion from the White Home learn, citing lithium as among the many “vital supplies.”
However essentially the most significant initiative, by far, is the not too long ago handed Inflation Discount Act. The invoice, which is the biggest local weather funding package deal in U.S. historical past, focuses on incentives and credit aimed toward accelerating the U.S.’ shift in the direction of renewable power whereas additionally jumpstarting home manufacturing.
The invoice contains measures that can assist battery corporations on each the provision and demand aspect. Over time, a higher portion of an electrical automobile’s battery supplies should be sourced from the U.S. or one among its free-trade allies to ensure that customers to qualify for the tax rebates. Producers may also make the most of the manufacturing tax credit.
Narwold referred to as the Inflation Discount Act a “nice step ahead.”
“It actually does give the impetus to begin focusing domestically on constructing that provide chain. No purpose why the USA cannot be a big contributor to that provide chain with the suitable assist, each from the federal government – state and federal – in addition to from the business,” she mentioned.
