Invitation to the Lithium Workshop at Geotherm 2022

The UnLimited research project invites you to participate in the workshop "Extraction technologies from geothermal brines for lithium recovery" at this year's Geotherm in Offenburg. The focus will be on the technical approaches and processes of lithium extraction from geothermal brines, as well as further processing. Participation in the workshop is free of charge for all Geotherm visitors.

Experimental research on alternative lithium sorbents

As part of the UnLimited project, various sorbents are currently under research considering a sustainable lithium extraction from geothermal fluids in Germany. Experiments in the laboratory revealed a higher lithium adsorption capacity of zeolites. Thus zeolites may represent promising alternatives to manganese oxides.

Sustainable Geothermal Lithium Triangle in the Upper Rhine Graben

Currently, the co-production of lithium from deep geothermal plants is being discussed worldwide and has already been implemented locally on a pilot basis. Especially in the field of electro vehicles, the demand for lithium is increasing rapidly. In Europe, there are well identified exploitable resources for lithium in the Upper Rhine Graben from Alsace in France to Germany near Mannheim where the deep geothermal brines reveal lithium contents up to 200 mg/L.

First UnLimited annual general meeting

The first general meeting was successfully held on November 26, 2021. Due to the pandemic situation, the project partners came together digitally and presented the results of the UnLimited project so far. Since the start of the project in December 2020, relevant outcomes have already been achieved in the individual work packages.

Lithium products: Different types of lithium

Pure lithium is very reactive in air. It is therefore produced and processed in the form of various lithium salts. Lithium carbonate and lithium hydroxide dominate here, but also lithium chloride. Due to the different densities of these compounds, the term "lithium carbonate equivalent" (LCE) was introduced for better comparability.

UnLimited meets Li+Fluids

BGR is coordinating an interdisciplinary research network to develop the basis for a raw material strategy for lithium extraction from thermal water in Germany. The client of the "Li+Fluids" project is the German Federal Ministry for Economic Affairs and Energy (BMWi).
