Low-medium temperature geothermal heating and cooling solutions

GEOTHERMICA Initiative, CETPartnership TRI4 Heating & Cooling, and Geological Survey Ireland organised a workshop at the EPIC Museum in Dublin on 10 October 2023. The workshop focused on low-medium temperature geothermal heating and cooling solutions for campuses and cities. Around 50 people from 11 countries attended the workshop (from Ireland, the United Kingdom, Canada, Sweden, Iceland, Scotland, Germany, Belgium, The Netherlands, Switzerland, and the United States). 

Representatives from the European Geothermal Energy Council, Geological Survey Ireland, GEOTHERMICA Initiative, and CETPartnership TRI4 Heating & Cooling gave an overview of the geothermal sector in Europe and insights into the latest developments. 

Speakers from academia, research, and industry presented projects from the Netherlands, Ireland, Canada, the United States, Scotland, Switzerland, and Iceland on geothermal heating and cooling solutions for campuses and cities. Below, you can find their presentations.

The workshop highlighted promising concepts for utilizing low- and medium temperature geothermal energy for the heating and cooling transition of cities and campuses. Discussions during the workshop underlined the potential, as well as the need take a broad perspective on low- and medium temperature geothermal in future activities, for example in the Calls of CETPartnership TRI4 Heating and Cooling.
