Study finds that Germany's lithium reserves can sustain domestic demand for decades

Study finds that Germany's lithium reserves can sustain domestic demand for decades

A study released on Thursday showed that Germany has enough lithium reserves for its own needs over several decades. Berlin is trying to increase its production of electric vehicles and reduce its dependence on imports.

According to the German Raw Materials Agency, Germany's lithium consumption could reach up to 0.17 millions metric tons annually by 2030. The German automotive industry imports lithium from Australia, Argentina Chile and China in order to meet its battery production requirements.

Researchers and companies are exploring ways to extract the lithium byproduct from geothermal energy in Germany's Upper Rhine Valley, to increase domestic supply as well as renewable heating and electricity solutions.

The Federal Institute for Geosciences and Natural Resources and Fraunhofer IEG found that Germany has up to 26,51 million metric tonnes of lithium in deep underground water, especially in the North German Basin and central Thuringian Basin.

This assessment of potential was new. "When you add it all up, there are surprisingly large lithium reserves lying dormant below the earth's surface," Katharina A. Alms, Fraunhofer IEG research leader, said.

Geologists estimate that in 2021 the Upper Rhine Valley, located in the Black Forest region of southwest Germany, will hold enough lithium to power more than 400,000,000 electric vehicles.

Despite concerns about the difficulty of extracting lithium, Lithium exploration in Germany has increased.

Esso Deutschland, a subsidiary of ExxonMobil, received four exploration licenses in Lower Saxony last December. Neptune Energy, a German oil company, announced in August that it had received exploration permits in the eastern state Saxony Anhalt.

Alms stated that extracting lithium from Germany is not easy as there are no high concentrations everywhere, and exploration can be unpredictable.

She added that many of the lithium deposits are trapped in rocks with low permeability, which makes extraction difficult. Surface extraction methods can also be time-consuming and complex to implement at large scales.

According to the ZVEI trade group, Germany will import 23.7 billion Euros worth of lithium batteries by 2023.
