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

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).


Preliminary program of the workshop


8:30 Registration and get together
9:00 Opening of the workshop and welcome addresses
Riga Technical University
COST Action Geothermal-DHC: Gregor Goetzl (chair)


9:30 – 12:00 Morning session – technical lectures on low temperature heating and cooling grids in context of shallow geothermal
Invited speakers will share theoretical and practical experience on:
• low-temperature heating and cooling grids
• multivalent heating and cooling grids using underground heat storage
• geothermal DHC lighthouse projects and 5GDHC
• economic aspects and business models


Confirmed speakers: Rao Martand Singh (NTNU, Norway), Peter Altenberg (The Heat Academy, Sweden)
Each lecture is scheduled for 30 minutes including Q&A round

12:00 Lunch break
13:00 – 15:20 Open forum on policies and R&I linked to geothermal energy use in the Baltic region


Local research and energy industry stakeholders will present the state of the art and future development challenges of the DHC networks and energy infrastructure in the Baltic region. Topis will cover:

  • State of the art of DHC networks
  • Geothermal potential in Baltic region
  • Lessons learned from existing geothermal case studies
  • New business opportunities and challenges for existing energy infrastructure

Each lecture 20 minutes


15:20 - 16:00 Panel discussion: “Pathways to introduce geothermal energy supported DHC networks and use of geological potential in heating sector”
All speakers will be involved.
