Dear colleagues,

we cordially invite you to our two-day retreat:

Lithium co-extraction with geothermal heat from Rotliegend formations in the Brandenburg area

Time: 7^th to 8^th of November, 2024; each day: 9 am to 6 pm

Language: The Workshop language will be mostly in German.

Place: Seminar- und Gästehaus Flussbad Gartenstraße, Gartenstraße 42-48, 12557 Berlin

The Rotliegend Sandstone formation in Brandenburg offers strong advantages such as high lithium content and high temperatures for co-extraction of geothermal heat and lithium from the fluids. However, so far, the feasibility has not been demonstrated due to many uncertainties, associated risks and unanswered research questions. To answer those questions and provide a pathway for future co-extraction, the consortium plans to write a research proposal that involves the set-up of a demonstrator well. The workshop addresses many disciplines from both, research (geoscientists, chemical engineering, chemists) and industry. We will work in six groups: (1) geology/site selection; (2) drilling technology; (3) extraction technologies (4) fluid-rock-interaction (5) upscaling and above ground technology (6) acceptance, market, economic aspects.

Since the space is limited, we ask interested people who want to join to contact the organizers before for more detailed information (Simona Regenspurg: regens@gfz-potsdam.de). If you plan to attend the workshop for one or two days, please get also informed about the regional geology (Brandenburg) and formulate your research questions before.

On behalf of the organizing team,

Simona Regenspurg (GFZ Potsdam)
