The Chair for Geochemistry and Economic Geology deals with the cycle of elements in the Earth and its atmosphere. Inspired by this definition three research groups with the focus on different aspects were formed

Our well equipped laboratory forms the basis of our work.

We develop by our research innovative technological solutions for the societal challenges like change to low-carbon energy and mobility systems, global welfare and resilient adaption to as well as reduction of anthropogenic climate change. We focus on sustainable access to raw materials and protection of our environment.

Alle unsere „Wenden“, vor allem die Mobilitätswende und die Energiewende, hängen davon ab, dass wir über diese Rohstoffe frei verfügen können - Prof. Jochen Kolb

Article in "The Parliament" - Europe's quest for home-grown lithium

Local energy company Energie Baden-Württemberg (EnBW) is working with researchers from Karlsruhe Institute of Technology (KIT) to develop a process to extract tonnes of battery-grade lithium from the hot, salty water that powers the Bruchsal plant. If their project succeeds, it could produce Europe’s cleanest supply of lithium.

New project ResOpt launched

ResOpt is concerned with optimizing the combustion properties of biogenic residual and waste materials. The aim is to understand the formation mechanisms of deposits, to reduce their quantity and thus to increase the energy efficiency of biomass power plants.

Lithium for e-cars from thermal water

Most batteries and rechargeable batteries today contain lithium. In nature, this light metal only occurs in bound form, so it has to be dissolved in a complex process. This is not always done in an environmentally friendly way. Now a company wants to extract lithium in Germany as well - from Europe's largest groundwater reservoir.

Discovery of "rare earths" in Sweden

Interviews with Prof. Dr. Jochen Kolb on the latest discovery of a rare earth deposit in Sweden:

NDR (5:53): "Mining takes time".

SRF (7:01): What is the significance of the find?

SWR (4:31): Opportunity for environmental protection and less dependence on China.

Nothing works without China

An e-car without Chinese supplies? Completely unthinkable at present. Germany and Europe are trying to become less dependent on Chinese raw materials. But that is not so easy.
