1st Geothermal-DHC regional cluster workshop

The first Geothermal-DHC regional cluster workshop 

“Geothermal energy – unleashing the potential of supplying district heating and cooling networks in the Baltics”

Date and time of the workshop: 30th of September 2022, 09:00 am – 16:00 am (CEST)

Location: Riga, Latvia

About the workshop

Geothermal energy offers many advantages for the clean and sustainable energy transition by covering the demand of low temperature heat 10°C up to 150°C. Geothermal energy is a long-term stable and reliable heat source providing high system efficiencies and low surface space occupation. However, the overall share of geothermal inside the H&C market is still less than 2%, and in the Baltics almost negligible.

Our workshop focuses on a science to policy and industry dialogue on the opportunities and prevailing barriers towards a better integration of geothermal energy in multivalent heating and cooling networks at various temperature levels. These sessions will cover presentations regarding the state of the art in the Baltic countries and sharing the experience and consultancy on the introduction of geothermal energy followed by a moderated panel discussion focusing on strategies and needed measures to better integrate this technology into the DHC market in the Baltic region. Event will be held in a hybrid mode (in person and online).
