Promote Geothermal District Heating Systems in Europe (GEODH)

Download PDFDownload PDF
The objective of the GEO-DH project is to accelerate the uptake of geothermal district heating (GEODH), for ensuring security of supply and substitution of fossil fuels.Today, geothermal district heating (DH) technology is under developed although deep geothermal potential is significant and competitive. To reverse this situation it is necessary to identify and address the current barriers affecting the development of geothermal district heating.GEODH aims to remove administrative and financial barriers and to work alongside decision makers to facilitate the adoption of the right framework.The GEO-DH project focus on developing geothermal district heating systems in Eastern and Central Europe (BG, CZ, HU, PL, RO, SI) and in other EU countries with ambitious 2020 target (NL, DE, IT, FR) or with geothermal DH projects under development (DK, UK, IE).Recommendations (administrative, legal, financial and managerial) will be drafted to address the identified barriers and to contribute accelerating the market penetration of this technology. The sharing of best practice on technologies and on the implementation and delivery mechanisms will be achieved through the celebration of targeted workshops within regions and local authorities within 14 target countries. The accompanying promotional campaign will also increase the awareness on the applications and benefits of geothermal DH technologies.


  • Acceleration of approval procedures for geothermal DH by simplifying regulations of geothermal DH. In order to simplify these procedures, GeoDH project has proposed a set of recommendations for a favourable regulatory framework which have been presented to over 60 public authorities in 14 countries.
  • Attract more financing for geothermal DH systems . Innovative financial solutions have been proposed to finance Geothermal DH projects which are capital intensive. The project has elaborated a maual for support schemes, a guide on business models for geothermal DH and a guide on project management in order to attract more investments to the sector.
  • A total of 16 new plants (circa 16 MWth) have come to operation since the project started and 9 projects are under development.
  • Increased awareness of regional and local decision-makers on deep geothermal potential and its advantages. Know-how has been achieved via the elaboration of  best practices and by training national and local authorities (more than 500  trainees) . An online GIS viewer showing the potential of geothermal district heating in 14 EU MS is ready

Lessons learned

  • There are no technical limitations to the deployment of geothermal DH in Europe. This project received many interest during the 14 workshops organized in 2012/2013.
  • Long discussions took place to define the best methodology for collecting data on geothermal and DH potential. In the end, a solid methodology has been adopted in order to be used for reaching our final objectives: create a web-GIS on geothermal potential in Europe for geothermal DH.
  • The financial issue is the number one all over Europe to finance geothermal DH projects. The geological risk associated to (deep) geothermal district heating projects remain a key barrier. These risks should be covered with  risk insurance schemes. Examples of this exist in Europe.
The project is now closed.
