US Seeks New Lithium Sources as Demand for Batteries Grows

The race is on to supply extra lithium in the US. The US will want much more lithium to realize its clear power targets — and the business that mines, extracts and processes the chemical ingredient is poised to develop. However it additionally faces a bunch of challenges from environmentalists, Indigenous teams and authorities regulators.

Though lithium reserves are distributed broadly throughout the globe, the US is house to only one lively lithium mine, in Nevada. The ingredient is vital to growth of rechargeable lithium-ion batteries which are seen as key to lowering climate-changing carbon emissions created by vehicles and different types of transportation.

Worldwide demand for lithium was about 350,000 tons (317,517 metric tons) in 2020, however business estimates mission demand might be as much as six occasions larger by 2030. New and potential lithium mining and extracting tasks are in numerous phases of growth in states together with Maine, North Carolina, California and Nevada.

“Nobody really foresaw this huge spike in demand,” stated Tim Crowley, vp of presidency affairs for Lithium Nevada, a subsidiary of an organization growing a mine in Thacker Move, Nevada. “We owned the lithium space for a long time, and we forfeited it to China.”

A lot of the world’s lithium comes from South America and Australia, and China dominates the worldwide provide chain for lithium-ion batteries. The US produces lower than 2 p.c of the world’s provide of lithium, though it has about 4 p.c of the reserves. The biggest reserves on the planet are in Chile.

Increasing home lithium manufacturing would contain open pit mining or brine extraction, which includes pumping a mineral-rich brine to the floor and processing it. Opponents together with the Sierra Membership have raised issues that the tasks may hurt sacred Indigenous lands and jeopardize fragile ecosystems and wildlife.

However the tasks may additionally profit the surroundings in the long term by getting fossil fuel-burning vehicles off the highway, stated Glenn Miller, emeritus professor of environmental sciences on the College of Nevada.

“A domestic source has tremendous value. Then we can do things that only China is doing with production,” Miller stated.

Lithium — the lightest steel on Earth — was found by Swedish chemist Johan August Arfwedson greater than 200 years in the past. Since then, lithium and its compounds have been utilized in the whole lot from psychiatric drugs to lubricating grease.

However curiosity in lithium has exploded in recent times due to its use in rechargeable batteries for electrical and hybrid vehicles, lawnmowers, energy instruments and extra. Lithium batteries additionally energy laptops and cell telephones.

The Biden administration has made a plan for half one million charging stations for electrical autos a signature piece of its infrastructure targets. That effort, and the expansion of electrical car corporations such as Tesla, would require way more lithium to make batteries.

The brand new lithium mining mission closest to growth is the one proposed for Thacker Move by Lithium Americas. That northern Nevada mine would make tens of millions of tons of lithium out there, however Native American tribes have argued that it is positioned on sacred lands and must be stopped.

Building may begin late this 12 months, stated Lithium Americas CEO Jonathan Evans, noting that it will be the primary lithium mission on federal land permitted in six a long time.

Evans stated there’ll seemingly be extra US makes an attempt to extract lithium due to the rising demand. “It has been a small business and it has grown rapidly,” he said. “I do expect larger companies to enter the space via acquisitions or other means.”

Australian-based Ioneer also wants to build a large lithium mine in Nevada, which the company says is expected to produce 22,000 tons (19,958 metric tons) of lithium — enough to power hundreds of thousands of electric vehicles annually.

Lithium mining projects represent a challenge for environmentalists because they carry the promise of decarbonisation in exchange for heavy impacts on ecosystems and local communities. Lithium mining could jeopardize water quality and ranching in some states, the Sierra Club has argued.

The big challenge is making sure lithium mines are located in places where they do the least amount of damage, said Lisa Belenky, senior attorney for the Center for Biological Diversity.

“It really is very site specific as far as what impacts it would have to the local species, water,” Belenky said. “Almost every energy project we look at for climate change has its own greenhouse gas footprint.”

The drive for extra home lithium has opened the potential for mining and extracting in states past Nevada. An Australian firm known as Piedmont Lithium desires to develop an open-pit mining mission it has proposed for the Kings Mountain space west of Charlotte, North Carolina. The realm was a serious provider of lithium from the mid-Twentieth century into the Nineteen Eighties, the corporate stated.

California’s largest lake, the salty and shrinking Salton Sea, can be primed to host lithium operations. Lithium will be extracted from geothermal brine, and the Salton Sea has been the location of geothermal vegetation which have pumped brine for a long time. Proponents of extracting lithium from the lake stated it will require much less land and water than different brining operations.

One mission, led by EnergySource Minerals, is predicted to be operational subsequent 12 months, a spokesperson for the corporate stated. Common Motors Corp. can be an investor in one other mission on the Salton Sea that would begin producing lithium by 2024.

Gov. Gavin Newsom, a Democrat, envisions that California’s lithium can place the state to turn out to be a pacesetter within the manufacturing of batteries. He known as the state the “Saudi Arabia of lithium” during a January address.

Dee Dee Myers, a senior adviser to Newsom focused on business, said that lithium is an “increasingly critical resource” as California and the world pursue clean energy development to slow climate change impacts.

The state has an opportunity to produce “epic quantities of lithium” given the resources around the Salton Sea, Myers said. But she said it wants to ensure lithium is extracted and produced sustainably.

State government could play a role in regulating the extraction process. In 2020, California also created the Lithium Valley Commission to review and analyse incentives for lithium extraction. They must file a report with their findings by October.

In Maine, Plumbago Mountain in the western part of the state has attracted mining interest. The mountain is “a potentially significant new lithium resource,” with a higher average lithium content than similar deposits around the world, according to a 2020 paper in the scientific journal Mineralium Deposita.

However, Maine mining regulations could make it difficult to extract the lithium. The Maine Department of Environmental Protection is reviewing the possibility of quarrying for lithium at Plumbago at the request of the property’s owners, state mining coordinator Mike Clark said.

Plumbago Mountain is the kind of site that could be significant for the US as it seeks to fulfil its clean energy goals, said Alicia Cruz-Uribe, an associate professor of petrology and mineralogy at University of Maine.

The country’s lithium reserves rank among the largest in the world, Cruz-Uribe said. “But the amount that we produce is peanuts.”
