The day opened with a keynote by Argo Jõeleht (University of Tartu) exploring the Geothermal Energy Potential in the Baltic States, with a particular focus on Estonia and Latvia. This set the stage for a diverse series of talks spanning technological innovations, regional case studies, policy and permitting frameworks, and environmental considerations.

Presenters addressed both shallow and deep geothermal approaches, the integration of geothermal energy into district heating networks, and novel concepts like geopressured storage and “huff & puff” geothermal systems. Talks such as “Thermonet – An Enabler for Shallow Geothermal District Heating and Cooling” (by Søren Skjold Andersen, Termonet Danmark) and “Deep Geothermal Energy for District Heating in Denmark” (by Carsten Møller Nielsen, GEUS) offered valuable cross-border perspectives.

The importance of regulation and risk management was also highlighted through insightful presentations from Martin Bloemendal (TU Delft), Teppo Arola (GTK), Florian Smit (GEUS), and David Boon (British Geological Survey), who examined permitting procedures and environmental frameworks across Europe.

We are grateful to all of today’s presenters for their contributions:

Argo Jõeleht, Mayur Pal, Kimmo Korhonen, Aivar Auväärt, Simonas Valadkevičius, Søren Skjold Andersen, Anna Volkova, Andres Veske, Carsten Møller Nielsen, Martin Bloemendal, Teppo Arola, Florian Smit, and David Boon.

Their expertise, insights, and discussions are helping to shape a more integrated and innovative geothermal future.

We now look forward to tomorrow’s field excursion to the EGT Arbavere Research Center and the new geothermal site at Roosna-Alliku, where participants will gain hands-on experience and see promising technologies in action.
