Moderation: Hjalti Páll Ingólfsson, Managing Director of GEORG
Meeting Chair: Dr. Marta Rós Karlsdóttir, Director of Sustainable Use of Natural Resources Orkustofnun, National Energy Agency of Iceland

Hosted by the Support Unit for IWG Geothermal (SU-DG-IWG), this is the second geothermal Roundtable, the first having been convened in Leiden back in 2019. Since then, the need to develop the geothermal sector further has become even more apparent and our community needs to press on towards Europe’s sustainable energy goals. This Roundtable aims to inform and coordinate the activities of the multiple different actors involved in geothermal, and hopefully shape the role of geothermal in the energy transition.

The IWG Geothermal has since its inception broadened the focus beyond the technical and set its sights on four key areas that underpin the strength of geothermal and its contribution to the energy transition: Heating & Cooling, Power Production, Thermal Storage and Geothermal Minerals. 

These areas will guide the discussion.

Morning session keynotes with focus on technical aspects of heating & cooling and power. Afternoon session with focus on innovation and the multi-use of geothermal

Time: 5:00- 6:30 PM

Venue: Oberrheinhalle, Conference Room 3
Moderation: BVG & the BWP and the Bavarian Geothermal Energy Association
Study presentation: "Contribution of geothermal heat pumps to the heat transition - obstacles and recommendations for action", Fraunhofer IEG

"Heat pumps have a key role to play in achieving the climate targets in the building sector. However, the market growth to date has mainly been driven by heat pumps with air as the heat source. Ground source heat pumps have hardly been able to participate in the strong market growth so far, although they are considered the premium solution for heating and cooling with heat pumps.  This short study was prepared by Fraunhofer IEG on behalf of BVG & BWP and the Bavarian Geothermal Energy Association. The study analyses the status and potential of ground-coupled heat pumps in Germany. Recommendations for action to improve the regulatory framework are derived from the description of current barriers. "

Presentation: Extraction technologies from geothermal brines for lithium recovery -
Time: 9.00-12.30 AM
Venue: Oberrheinhalle, K3
Moderation: Elif Kaymakci (EnBW, Project UnLimited)

As  the  impacts  of  climate  change  continue  to  increase  worldwide,  the  conversion  of energy supply to renewable energy sources becomes more urgent than ever. Not only electricity and heat but also the mobility sector represent key factors in that context. Along with the decarbonization of the automotive industry, the demand of lithium has increased significantly over time, due to its application  in  lithium-ion-batteries.  Currently,  the  extraction  of  lithium  from  geothermal brines  is researched in many places within Europe. Thereby, deep geothermal waters are associated with high 
salinity and mineralization and may contain high concentrations of dissolved lithium between 125 to 480  mg/L.  The production  of  sustainable  lithium  from  geothermal  waters  within  Central  Europe therefore offers the chance to make a valuable contribution to achieving global climate goals. 

Various methods are available for lithium extraction from geothermal water, referred to as “direct lithium extraction (DLE) processes”. In this regard, this session will address the different technical approaches of  lithium  extraction  from  geothermal brines  as  well  as the  subsequent  processing  of lithium after DLE. Participants of several R&D pilot projects in Germany, France and the UK will provide insights into the scientific and technical aspects and challenges.
