Earlier this year, Goldman Sachs released a report claiming that the world will soon see an “oversupply” of the metals needed to make lithium-ion batteries that power electric vehicles into a greener one. Facilitate economy. Industry experts and consultants disagreed and soon after released a storm of criticism that contradicts the report: There is no imminent surplus of battery materials – metals such as nickel, cobalt and lithium – but a driving shortage, they said.
“I think one of the critical things that may have been misunderstood by this report … is [that] there is a very big difference between capacity and proper supply,” said James Mills, a consultant at Benchmark Mineral Intelligence – a Market intelligence and price reporting critical of Goldman report – said The Dispatch. “As a Chinese chemical manufacturer, I can develop additional capacity to produce the latest chemical materials. However, this capacity will never run at 100 percent utilization, especially during that Ramp Up period.
The Biden administration has often expressed its support for moving the US economy to more sustainable energy sources. On his first day in office, President Joe Biden reconciled with the Paris Agreement, an international climate action plan, from which the Trump administration withdrew the United States in 2020. announced that former Secretary of State John Kerry would serve his administration in the newly created role of the special presidential budget for climate change. “Today’s clean energy technologies are a critical part of the arsenal we must take advantage of to reduce energy costs for families, reduce the risks to our electricity grid and address the urgent crisis of a changing climate,” he said. Administration in a statement in June.
In a 2022 report, the Intergovernmental Panel on Climate Change estimated that simply maintaining existing policies worldwide would still lead to an increase of 3.2 degrees Celsius and average global temperatures around 2100 above pre-industrial levels (1850-1900), much more than 1.5-degree target set by the Paris Agreement in 2015 to avoid the worst effects of climate change.
How do lithium-ion batteries and larger ambitions fit into a green energy future?
Simply put, all renewable energy – whether solar, wind, hydroelectric or anything else – needs to be stored, and lithium-ion batteries have become an important solution to this problem. They are perhaps best known for powering electric vehicles.
Lithium-ion batteries have a high energy density – they store a lot of energy for their size and weight – and they are easier than previous battery technologies to charge and recharge, Daniel Schwartz, director of the Clean Energy Institute at the University of Washington, told The Dispatch .
“They were the battery of preference for consumer electronics, for mobile devices where you want to pack more energy into a small package,” Schwartz said.
Lithium-ion batteries consist of four main parts: a cathode, an anode, an electrolyte and a separator. The cathode often consists of a combination of metals such as nickel, cobalt and lithium; the anode is typically graphite; a lithium salt solution constitutes the electrolyte; and the separator is plastic. (Sometimes the electrolyte and separator are described together as one component.)
These batteries discharge energy as lithium ions move through the electrolyte from the anode to the cathode. The separator keeps the cathode out of the anode while ions pass through the electrolyte. An external power source can charge a discharged battery, bring the lithium ions back into the anode to restart.
Nickel and graphite are extracted by underground or surface mining. Cobalt is usually produced as a by-product of the processing of other minerals, such as nickel.
Lithium is typically extracted in one of two ways. The first, traditional hard rock mining, involves digging into the earth in search of the mineral spodumene, which contains lithium. The second, the salt extraction, involves pumping the underground lithium-rich salt water to the surface and evaporating it, then processing what is left.
So, will the world have the battery metals needed to keep up with the growing demand from the clean energy sector?
The strain on the supply, which Mills and others have warned about, could already be made known. Lithium prices are up a whopping 434 percent year over year, according to Trading Economics.
Mills also pointed to another issue overlooked by the Goldman analysis: Much of the market for these minerals consists of long-term contracts between suppliers and buyers, some with fixed prices and some with variable prices. This factor makes rapid adjustments to prices and supply unlikely. “It’s very hard to say, ‘Right, I’m going to produce this material, and I’m going to sell it on a spot market [a market in which goods and payment are exchanged directly].
“Certainly fixing a problem in 12 months is impossible,” Mills added, though he argued that supply could stop demand later this decade.
Even before the setback to the Goldman report brought the shortage to the forefront, experts were concerned about an undersupply of the metals needed for lithium-ion batteries. “I take everyone’s gigawatt – hour projections and take them back to the lithium required to do it, and most of them are so far beyond what the lithium industry can deliver,” said industry expert Joe Lowry, also known as “Mr. “Lithium,” Bloomberg said in April.
But as experts warn that the world is not producing enough of the battery metals to keep up with the coming years of demand, some observers have concerns about what is already being produced.
“Cobalt is a conflict mineral – it is a mineral where human rights and labor practices are not ideal for where it is extracted,” Schwartz said. The Democratic Republic of Congo (DRC) has supplied over 70 percent of the world’s cobalt by 2021 and holds nearly half of the world’s reserves, according to the U.S. Geological Survey. Of particular concern are the DRC craft mines, small operations responsible for 20 percent of the country’s cobalt production. They are known for their dangerous working conditions and for employing children.
But Schwartz told Dispatch that advances in the field are moving the technology away from its heavy reliance on cobalt. Cobalt, Schwartz said, “was quite common in the positive electrode – the cathode – of lithium-ion batteries, but now we have eliminated about 90 percent of it from the typical battery electrodes that go into vehicles.”
Obtaining other minerals, such as lithium, poses several problems. In the “lithium triangle” – which contains parts of Argentina, Chile and Bolivia – the metal is extracted by salts. Because this process requires evaporation from massive water basins and already arid regions, it destroys nearby ecosystems and communities of much-needed water, activists warn. Argentina and Chile combined accounted for about a third of the world’s lithium production by 2021 and accounted for over half of the world’s reserves, according to the US Geological Survey.
Another potential concern is China’s track over critical metals mining and processing – 15 of the DRC’s 19 cobalt-producing mines have links to Chinese companies.
“We can not build a future that is made in America if we ourselves are dependent on China for the materials that make up the products of today and tomorrow,” Biden said in February.
“[Here] today, China refines 60 percent of lithium and 80 percent of world cobalt, two core inputs to high-capacity batteries – which presents a critical weakness for the future of the U.S. violent automotive industry,” a June 2021 White House report states. The document raised concerns that China could restrict the export of these materials due to tensions with the US, sell substandard materials or involve the US in supply chains linked to human rights violations, including genocide – presumably a reference to the US-recognized genocide of China. Uyghur Population.
Battery metal mining is also not without environmental impact. The salt extraction used in South America pushes water to save areas with little water. In traditional mining, surrounding body water or contaminated groundwater can be used for agriculture or human consumption. A proposed mine on Thacker Pass, Nevada, for example, could contaminate groundwater under and around the mine over drinking water standards for hundreds of years.
Plus, mining itself requires immense amounts of energy, which often comes from burning fossil fuels. However, Argonne National Laboratory estimates that the life cycle of greenhouse gas emissions for an electric vehicle is less than half that of a comparable gas car. These figures take into account the energy used for the required materials, the manufacture of the battery and the charging of the electric vehicle.
The disposal of lithium-ion batteries exacerbates further environmental problems. When used lithium batteries are dumped in landfills, they can discharge pollutants as they degrade, or even lead to landfill fires.
“We’re still learning about recycling and recycling,” Schwartz told The Dispatch. “So, that’s something that really, I think, is a border area.” He added that while economic considerations could lead to technological advances in battery recycling, “recycling will be driven by sound policies.”
Schwartz said that in the end, the total environmental cost of mining for battery metals should be weighed against that of fossil fuel extraction: .
So what is the US response to these issues?
The answer, for the most part, seems to be “dig, baby, dig” – or at least try. In recent years, a series of executive actions have pushed the U.S. to produce more battery metals in-house.
In June 2021, the Federal Consortium for Advanced Batteries released a “national blueprint for lithium batteries”. It recommended, among other things, that the United States encourage more domestic mining. By 2021, the U.S. will produce less than 1 percent of the world’s cobalt and nickel, according to the U.S. Geological Survey. The agency did not report international lithium production to protect the proprietary data of the only lithium mine operating in the United States.
On February 24, 2022, the Secretary of the Interior updated a 2017 executive order issued by former President Donald Trump that directs federal agencies to increase U.S. involvement in the supply chain of “critical minerals” as well as deliver and streamline better data. Permission processes for their house building. The update added nickel to the list of critical minerals that already contain graphite, cobalt and lithium.
On 31 March, Biden enacted the Cold War-era Defense Production Act to ensure the reliable production and supply of materials critical to the clean energy economy, including metals such as graphite, lithium, cobalt, and nickel.
“While it is too early to assess the impact of that order, the signal it has sent to markets, the global community and miners has been significant,” said Conor Bernstein, a spokesman for the National Mining Association (NMA), the Dispatch in a statement. “The engagement is well underway between the Ministry of Defense and industry and there is significant interest from our members. Without a doubt, the administration’s early and intensive focus on mineral supply chain challenges and the recognition of the importance of minerals for key pieces of the agenda reaching out to the President has raised issues that we have been talking about for years and the middle stage.
Mills agrees: “I think [Biden’s series of executive actions] puts a lot of downward pressure on those regions that are developing some of these assets.”
But the US can be a challenging environment for mining. Attempts to found battery metals in the home have seen varying degrees of success. In Minnesota, Nevada, Idaho, North Carolina, and a handful of other sites across the country, problems have arisen: environmentalists worry about damage to ecosystems, indigenous peoples groups against disruption to culturally significant land, homeowners who do not want mines and their backyard, and government regulators are moving slowly.
“[Where] the administration wants to go with the speed at which it has articulated, it requires immediate attention to the bottlenecks and redundancies in our mine clearance processes,” Bernstein said. “The administration needs to commit to building the safe, secret industrial base of tomorrow and that starts with the permit.”
A 2017 report prepared for the NMA by SNL Metals & amp; Mining, an industry data firm, estimates that mining projects in the United States have a seven- to 10-year licensing process that passes through various state and federal agencies and opportunities for public contest. According to the report, the average permit period in Canada and Australia is a relatively short two years.
“I think if there is a clear framework on how these projects can get positive support, in essence, that will speed up that process,” Mills said. And he believed that the recent pressure from the Biden administration could encourage that.
Twin Metals Minnesota, a company that hopes to build a copper and nickel mine in northeast Minnesota, is an example of a less than successful attempt at home construction. The company presented its first of many permit applications, this one for a “pre-feasibility study”, back in 2012. But in a big profit for locals concerned that the contamination of the proposed mine would harm the nearby Boundary Waters Canoe Area wilderness would. The Biden administration canceled the Twin Metals mineral lease earlier this year after concluding that it had been unfairly renewed under the Trump administration in 2019.
Glenn Miller, an Emeritus Professor in the Natural Resources and Environmental Science Department at the University of Nevada, is typically a critic of the mining industry. But the importance of lithium for lithium-ion batteries in a green economy led him to support the development of the lithium mine in Thacker Pass, Nevada, a project that drew fierce opposition from local indigenous groups. “I have been teaching environmental science courses for years and realize that the importance of climate change is not to be underestimated,” he told The Dispatch.
“I think lithium is really important. I’m a strong supporter of a home source of lithium,” Miller added. “And the Thacker Pass seems to be pretty good compared to some of the other, gold mines we have.”
