Western governments should consider stockpiling critical battery metals, such as cobalt and lithium, the International Energy Agency (IEA) said in a report yesterday, in a stark warning of the geopolitical risks that accompany the green energy transition.
That call comes as some policymakers worry the shift from burning fossil fuels to a greener economy would expose the world to new threats.
Unlike oil, a relatively ubiquitous commodity, production and processing of minerals, such as lithium, cobalt and some rare earth elements, is highly concentrated, with the top three producers accounting for more than 75 percent of global supply.
Stockpiling programs could provide a valuable buffer as leading industrial nations look to develop reliable supplies of metals and minerals that would play a critical role in a decarbonizing world, the energy watchdog said.
“Meeting our climate change goals will turbocharge demand for mineral resources,” IEA executive director Fatih Birol said by telephone. “Voluntary strategic stockpiling can in some cases help countries weather short-term supply disruptions.”
The IEA was founded in 1974, following the first global oil shock as leading industrial nations, including the US, Japan and Germany, sought to enhance energy security through stockpiling.
Those strategic oil reserves have been used several times, including during the Gulf War in 1990-1991 and during the Libyan civil war in 2011.
The influential watchdog is urging governments to brace against new supply risks as the world becomes increasingly reliant on an array of critical minerals that are often only produced at scale in a handful of countries.
Building new strategic reserves could have unintended consequences, potentially boosting demand and prices as governments vie with automakers for scarce metals.
Commodities from copper to palladium are already soaring, as the global economy rebounds from the pandemic.
While China and Japan have strategic inventories of critical metals, such stockpiles are not widely held by Western nations.
China also has a strong presence in the processing of such metals, as well as producing about 60 percent of the world’s rare earth elements.
The US maintains a stockpiling program through the Defense Logistics Agency, but there have been few large-scale purchases since the Cold War, when metals, such as cobalt, first gained strategic importance as an alloy in jet engines.
Now cobalt plays a crucial role in high-capacity lithium-ion batteries of the type used by Tesla Inc.
Cobalt has become a particular concern because the Democratic Republic of the Congo — a conflict and poverty-wracked African nation — accounts for more than 70 percent of the supply worldwide.
Earlier this year, the US Department of Energy said that the nation lacked “sufficient domestic resources to meet expected demand for certain critical materials, such as cobalt and gallium.”
Partnerships with allies to build supply chains and developing substitutes were among the department’s recommendations.
To address the looming challenges, the IEA advocates boosting recycling of raw materials and setting a clear policy agenda to encourage miners to develop new sources of supply.
The agency also joins investment banks and commodities trading houses in warning that rising demand during the energy transition could drive markets like copper into deep deficits.
MARKET BOOST: Elon Musk said Tesla would resume bitcoin transactions once there is ‘reasonable’ clean energy usage by miners and denied selling a big part of his holdings Bitcoin yesterday hit a two-week peak just shy of US$40,000, after another weekend reacting to tweets from Tesla Inc chief executive Elon Musk, who fended off criticism over his market influence and said Tesla sold bitcoin, but might resume transactions using it. Bitcoin has gyrated to Musk’s views for months since Tesla announced a US$1.5 billion bitcoin purchase in February and said it would take the cryptocurrency in payment. He later said the electric vehicle maker would not accept bitcoin due to concerns over how mining the currency requires high energy use and contributes to climate change. “When there’s confirmation of reasonable
China Steel Corp (中鋼), the nation’s biggest steelmaker, yesterday said that it would not be raising prices for some products next month, ending 12 consecutive months of increases. “There is a discrepancy between China Steel’s prices and international prices, but in consideration of price stability, we have decided not to adjust upward monthly-priced products,” the company said in a statement. That means the price of hot-rolled steel plates, hot-rolled steel coils, cold-rolled steel coils and other monthly-priced items would not change next month. However, the cost of other items priced seasonally would be going up, the company said, adding that prices of products
Synopsys Inc, a US-based electronic design automation solutions provider, yesterday said that it has signed up more than 20 of its clients for the latest device made using the most recent advanced process developed by Taiwan Semiconductor Manufacturing Co (TSMC, 台積電). Synopsys’ DesignWare IP, which is used by designers of integrated circuits, has been used by more than 20 clients in a wide range of industries, including automotive electronics, artificial intelligence, high-performance computing devices and servers, the company said in a statement. The DesignWare IP solution was made using TSMC’s advanced 5 nanometer process, its latest technology, which the semiconductor giant launched
MOVING ON UP: Taiwan improved in all four areas measured by the IMD, making its biggest leap, from 17th to sixth place, in economic performance Taiwan moved up three spots from last year to place eighth, its best performance since 2013, in the latest annual world competitiveness rankings, released yesterday by the International Institute for Management Development (IMD). Innovation, digitalization, welfare benefits and social cohesion are critical to economic performance, with Switzerland, Sweden, Denmark, the Netherlands and Singapore making up the top five on the list this year, the Switzerland-based institute said, after grading 64 countries and regions based on economic performance, infrastructure, and government and business efficiency. “Leading performers are characterized by varying degrees of investment in innovation, diversified economic activities and supportive public policy,” IMD
