This workshop, jointly organized by the EU-Horizon Action “SAPHEA” (, the EU COST Action “Geothermal-DHC” ( and VIA University college (Aarhus, DK) will address key questions related to make investments into geothermal energy solutions in heating (and cooling) networks more attractive, such as:

  • How to address legislation and policymakers? “The hen or the egg” type of problem
  • How to construct the right value proposition?
  • How to secure consistent financing of geothermal DHC?

The workshop aims to learn from good practices across Europe and transfer ideas and solutions between the industry, municipalities and research in different European regions. Learn from the different approaches and further develop replicable and systematic concepts for future business models, which meet current legal and financial challenges.
The workshop especially addresses the following target groups:

  • R&D representatives focusing on geothermal, district heating / cooling and the heating and cooling sector in general
  • Energy suppliers, energy contractors, district heating operators
  • Representatives from municipalities
  • Energy planners and energy agencies

On this second day, we will explore the exciting realm of geothermal district heating and cooling projects and their proven success. More than 400 geoDH plants are in operation and 300 projects are under development.
We will first set a policy session. The conference will then focus on securing the financing of renewable-based heat networks, considered riskier by investors.
It will showcase a selection of district heating geothermal projects that have achieved remarkable results, sharing valuable lessons learned and providing general guidelines to inspire and guide future developers. Furthermore, we will present thriving business models that have demonstrated exceptional effectiveness in the geothermal sector and discuss how to provide heat to the industry and sell your heating to clients.
Topics to be presented:

  • Market trends
  • Market conditions
  • Best practices and developments
  • Improving the socio-economic boundary conditions (financing, competitiveness, acceptance)
  • GeoDH in 2030 and in 2040: potential & opportunities
