11:00-18:00 CEST


Geothermal energy as well as district heating have a long tradition of use but still cover a marginal niche of around 1% of the European heating and cooling supply. In contrast, both concepts have a significant potential to cover future heating and cooling demands in the future at low costs, low emissions, high level of efficiency and supply guarantee. The benefits of Geothermal District Heating and Cooling must be made available to users so that society contributes to the increase in demand for these technologies.


The Geothermal District Heating and Cooling Day connected science and society by presenting recent developments and prospects, supporting the interlinking of stakeholders across Europe and jointly address present challenges and barriers for the deployment of geothermal energy supported heating and cooling networks in Europe.

Due to the special opportunity given by the European Geothermal Congress 2022, the first Geothermal District Heating and Cooling Day event had a strong focus on interconnecting researchers related to geothermal energy use in heating and cooling networks from a trans-disciplinary perspective.

During the afternoon session, CROWDTHERMAL held its final conference. During the Conference, the project team presented a set of reports, addressing social, environmental, financial, and risk mitigation aspects of community-financed geothermal projects.

The event was held in Berlin on 20 October 2022 as a side-event of the European Geothermal Congress

The mission of the Horizon 2020-funded CROWDTHERMAL project is to empower the European public to directly participate in the development of geothermal projects, with the help of alternative financing schemes and social engagement tools. CROWDTHERMAL aims to initiate a new form of public dialogue, during which it will be possible to jointly tackle concerns and increase interest in geothermal energy. The aim is to take public engagement to a new level, empowering citizens to directly participate in the development of geothermal projects with the help of alternative financing, such as crowdfunding. This will only be possible if public trust can be gained, and the transparency around geothermal projects (and their social and environmental impacts) can be maximised.

The EU COST Action CA18219 Geothermal-DHC represents a network addressing the integration of geothermal energy into decarbonized heating and cooling networks addressing the full range of geothermal technologies. Geothermal-DHC investigates concepts related to shallow geothermal in local heating and cooling networks (“5th generation networks”) towards direct geothermal energy use for district heating supply. Geothermal-DHC offers an inclusive European network currently covering more than 100 researchers and non-scientific stakeholders from around 40 countries around the world.
