Unstable Mineral Supply Threatens Electric Car, Green Projects

Unstable Mineral Supply Threatens Electric Car, Green Projects.

“Oceanic or space-base mineral reserves will become a plausible source”

The advent of the electric car is threatened by a few known knowns like range anxiety, high prices, and a thin recharging network, but now, according to a report from the University of Sussex, lurking in the background are possible shortages of the raw materials at the heart of this low-carbon revolution, which threaten to derail the whole project.

Making sure of adequate supplies is so important, mining under the sea, or even on other planets, would be justified, according to the report.

The automotive industry in Europe has been spending massively to embrace the electric car. On Thursday, Europe’s number one auto maker, Volkswagen, raised the stakes of its electric plans by bringing forward its target of producing one million electric cars a year by two years, to the end of 2023. By 2025 this will reach 1.5 million a year.

VW has a 33 billion euro ($37 billion) electric car investment plan through 2024. It has said by 2025, at least 25% of its global sales will be all-electric. Other giants of the European and global industry have similar, if perhaps not quite so adventurous, electric plans.

But what if the steady supply of crucial minerals was disrupted, like cobalt, copper, lithium, cadmium, and rare earth elements needed for autonomous cars’ photovoltaics, batteries, electric motors, wind turbines, fuel cells? 

According to a report published Friday by Britain’s University of Sussex, the green revolution could be at risk unless new international agreements and government mechanisms are put in place to ensure a sustainable supply of these crucial mineral components.

According to Benjamin Sovacool, Professor of Energy Policy at the University of Sussex and a co-author of the report, not only is the mining of some of these important minerals often dangerous to miners, but some countries which source these rare minerals are unstable and this could lead to unreliable supply.

The adequate supply of these crucial components for a low-carbon future is so important, it might be justifiable to open up mining at undersea locations, or even seek them on other planets.

Moon, here we come
“As the extraction through terrestrial mining becomes more challenging, the on-land reserves of some terrestrial minerals dwindle or the social resistance in some countries escalates, even oceanic or even space-base mineral reserves will become a plausible source,” Sovacool said in the report.

Sovacool said the Clipperton Fracture Zone, a 4,500 mile-long area in the Pacific Ocean off Central America, has huge reserves of manganese, nickel, copper and cobalt.

In an interview, Sovacool said cobalt demand in electric vehicle batteries was predicted to grow 200% between 2018 and 2020, and by another 500% by 2025.

“Previous studies have shown that demand will outweigh reserves in the not too distant future; estimates put the demand for cobalt at over 400% of current reserves by 2050, with Lithium demand also exceeding 100% of reserves by then,” Sovacool said.

“Three of the top five countries – Bolivia, China and Argentina with largest recoverable lithium stocks are associated with high forms of institutional risk and are not producing relative to their reserves. The U.S. Geological Survey’s 2019 mineral commodities summary cites Chile as having roughly three times the lithium reserves of Australia, despite Australia producing 51,000 tons to Chile’s 16,000 tons. Similarly, Argentina’s 14.8 million tons of resources and 2,000,000 tons of reserves only produced 6,200 tons of the 85,000 mined in 2018 while Bolivia has yet to even develop its resources despite the supposed 9 million tons of lithium embedded in its geological formations,”  Sovacool said.

Government intervention required
The mining industry isn’t taking the low-carbon revolution seriously and needs to make it a priority. Governments need to intervene to refocus minds, but he didn’t say how.

“The mining industry has yet to adequately shift its focus and resources on to these vital minerals and metals in order to meet the projected demand. The U.S. Geological Survey’s most recent exploration review shows that gold and silver still accounted for the majority of active exploration sites, and that the renewable materials market is not a priority. Government intervention will also likely be necessary to aid in addressing knowledge externalities,” Sovacool said.

    An intersting read, but shouldn’t the industry be focussing on reasearch and development of new battery tech that does not rely on rare minerals. We appear to be lurching from one crisis to another. Don’t we need to have a cognitive plan to invest heavily in renewable energy technologies that could provide a beter solution than the one available at present?
    Furthermore, has anyone considered that if everyone shifts from fossil fuels to electic vehicles, that the world’s electric generation capacity and distribution is somewhat underdeveloped to cope with the increased demand that this will bring.
