Georesources beneath our feet

16 Jun 2022, 09:30 → 17 Jun 2022, 13:00 Europe/Berlin

House H (GFZ Potsdam)

The North German Basin (NGB) underlies the southernmost North Sea and Baltic Sea as well as most of Northern Germany (including Kiel and Potsdam). It contains many sedimentary formations of interest for i) geothermal energy systems (including heat/cold storage); ii) sub-surface storage of nuclear waste, CO2 and H2; and iii) Europe’s largest Cu deposits.

The T8 Workshop “Georesources beneath our feet” will bring together researchers working on these different aspects of the NGB. The major aim of the workshop is to learn about NGB related research activities (recently finished, currently running, planned) of T8 scientists in GFZ, Geomar and UFZ; discuss the potential for future collaboration; and make use of existing expertise, data and models.

Corona Info: Please wear FFP2 masks when moving in House H. We kindly ask you to self-test before the workshop and do not participate if you feel any Covid Symptoms.

30 General Discussion

Guiding Questions:
Could we produce a "road map" document on the NGB describing potential uses of different Formations in the sub-surface and the associated ESG issues?
What would need to be done in terms of environmental baseline studies, monitoring, remediation if we want to use Formation X for Georesource Y etc. (coupling underground and above ground aspects)?
How do stakeholders choose if there is more than one potential use? What about governance of underground usage?

Where do we see the biggest potential for future research in the NGB?
Where do we see potential fields for cooperation between different centres and scientific fields?
What competences are missing?
How to make best use of new models, technical developments, existing infrastructure and generated data?
