In the valley alongside Germany’s Black Forest lies a potential answer to one of the crucial vexing points going through Europe’s transition to sustainable transport.
Some two miles underground is sufficient lithium for no less than 1 million electric automobiles a year, and one miner says it will possibly faucet these reserves at roughly half the price of competing sources and with out discharging greenhouse gases.

With the vital useful resource for battery-powered cars normally coming from far-flung areas utilizing strategies that scar the panorama, Vulcan Energy Resources’s 1.7 billion-euro ($2 billion) project could possibly be key for Europe’s ambitions to turn out to be the world’s first climate-neutral continent.
“We will produce a product locally that’s not only cheaper but also greener than the alternatives,” Horst Kreuter, Vulcan’s managing director in Germany, stated in an interview.
The company — backed by Australia’s richest girl Gina Rinehart — has signed provide agreements with Renault SA, Jeep-owner Stellantis and Korean battery producer LG Chem Last week, it landed its largest fish: a five-year cope with German auto big Volkswagen AG.

The Australian miner has now contracted most of its lithium manufacturing and plans to begin deliveries by 2026 on the newest.
But there are doubts. The project relies on know-how that hasn’t been deployed on a broad scale, and there have been indicators of native opposition over dangers that pumping lithium-laced brine to the floor might trigger tremors.
Short-seller J Capital Research criticised the group as being too optimistic. Vulcan stated the October report was “false and misleading” and sued the agency.
Despite the considerations, the project is pushing forward because it addresses the rising considerations over the environmental influence of constructing battery-powered cars. From lithium to cobalt, manufacturing a zero-emission automobile entails much more hard-to-get resources than standard cars and that comes at a price to the surroundings.
Amid intensifying world jostling for dominance of the electric-vehicle sector, the International Energy Agency in May really helpful that Western governments take into account stockpiling vital minerals comparable to cobalt, nickel and lithium. Already, automakers are stepping up battery-recycling efforts and pushing for a foothold in mining to achieve larger management over the resources wanted to make electric cars.
Volkswagen has arrange a facility in Germany to finally reuse 90% of battery elements. Mercedes-Benz maker Daimler AG is backing an initiative for extra sustainable manufacturing of cobalt, which has been linked to human rights abuses. Tesla Inc. struck a nickel cope with BHP Group Plc in July and agreed to a cobalt pact with Glencore Plc in June.
But the important thing useful resource is lithium. It was not often wanted within the petroleum-based economic system, however some 8 kilograms (18 kilos) are required for a trendy electric automotive.
Right now, the silvery-white metallic typically comes from open-pit mines in Australia or from South America, the place there are considerations about water waste and poisonous supplies launched from large evaporation swimming pools. The uncooked supplies are then shipped to Asia for processing. By the time the lithium results in European or American electric cars, a lot of carbon dioxide has been emitted.
As the transition gathers tempo, BloombergNEF expects demand for the minerals in lithium-ion batteries to develop fivefold by 2030. A world index of lithium costs has greater than tripled this year, buoyed by surging electric-car gross sales in China, the US and Europe.
Automakers are beneath stress to clear up their provide chains to meet sustainability targets, and Vulcan says Germany’s lithium can play a function.
For many years, geothermal vegetation within the Upper Rhine Valley have been pumping up scorching fluids from beneath the earth’s floor to generate electrical energy — a type of renewable energy. The services by no means bothered in regards to the lithium within the brine, however Vulcan plans to add an extraction step earlier than the fluid is reinjected.
About half of the electrical energy created within the course of would energy the lithium manufacturing, whereas the opposite half could possibly be bought. Vulcan has arrange a small pilot plant and in late September produced its first batch of battery-grade lithium. It plans to begin larger-scale manufacturing in 2024, Kreuter stated.
There are challenges to Vulcan’s technique. The brine is a sophisticated slurry together with potassium, iron, manganese and sodium — impurities that want to be filtered out earlier than the lithium could be put into batteries.
Public opposition has derailed new geothermal tasks, and locals are on the alert after previous incidents. In the Black Forest city of Staufen, dozens of buildings suffered cracks following geothermal drilling within the early 2000s. Just a few miles throughout the Rhine in France, authorities final year shuttered a geothermal plant close to Strasbourg after boring sparked minor earthquakes.
Producing industrial portions of the metallic from deep-well brines has by no means been carried out earlier than, and Vulcan nonetheless has to show it will possibly supply the money to arrange the vegetation. So far, the company has raised about 200 million euros.
Still, with lithium demand booming, the idea is catching on. BMW AG invested in Lilac Solutions, a US startup backed by Bill Gates that goals to extract lithium by way of a comparable technique from California’s Salton Sea. German utility EnBW AG can be learning the feasibility of manufacturing deep-well lithium within the Rhine valley.
Kreuter stated he’s assured Vulcan can persuade regulators and the general public that its project will make lithium manufacturing extra sustainable. For the company, the economics of the plan are simply as engaging.
“We can fund production of the brine via the sale of renewable energy,” Kreuter stated. On prime of that, “we don’t have the costs of developing and operating a mine.”
