Germany plans to mine major lithium deposit, the ‘gold of the electronic industry’

German-Australian startup Vulcan Energy resources plans to extract the rare earth element lithium, enough for 400 million electric cars, from a major deposit in the upper Rhine valley several kilometers underground, the company announced last week.

Lithium, dubbed the “white gold of the car industry”,  is one of the strategic rare earth elements that has become increasingly valuable with the growth of the electric car industry and is a key element for battery production. While actual worldwide reserves are difficult to estimate, the four countries with the biggest ones are Chile, Australia, Argentina, and China, with Chile’s confirmed reserves larger than the next three countries’ combined ones.

Vulcan Energy reserves co-founder Horst Kreuter recently told Reuters that they would start with the construction of five geothermal power plants, through which the extraction would work: the generators would be powered by hot water rich in lithium brought from deep underground, thus generating electricity with them and then chemically separating the lithium from this water and pumping the remaining water back underground.

The company plans to invest €1.7 billion for the venture, for which it currently has raised €75 million. They plan to bring in 15,000 tons of lithium hydroxide a year by 2024 and 40,000 tons a year from 2025.

Even with the projected demand growth — the European Commission expects demand to rise 60-fold by 2050 — the amount the company plans to mine is still very significant. Germany imported a total of 5,300 tonnes of lithium last year.
