Data & Viewers
This section provides access to SAPHEA’s key data-driven resources developed to support the strategic planning and market uptake of geothermal-based district heating and cooling systems.
At its core is the interactive GIS viewer, built on outcomes from the COST Action CA18219 (Geothermal-DHC) and enhanced by SAPHEA, showcasing existing geoDHC implementations across Europe. This tool offers users an intuitive visual interface to explore current projects, technical configurations, and regional distribution patterns.
Complementing this is the EU27 Financial Mapping Tool (Deliverable D4.2), which offers a structured overview of available funding schemes and financial instruments at national and regional levels—essential for early-stage project development and investment planning.
Additionally, SAPHEA’s Catalogue of Spatial Datasets (D2.3) is made available here as a curated collection of publicly accessible geodata relevant for geothermal planning. These datasets support regional assessments and can be integrated with local planning tools.
While the section is grounded in SAPHEA’s own deliverables, it also links to selected platforms developed in related EU projects—such as Hotmaps and EnerMaps—for extended insights and modelling capabilities.
Together, these resources offer a solid analytical foundation for stakeholders seeking to explore, evaluate, and plan geothermal heating and cooling systems across Europe.

Mapping of financial instruments (EU 27)
Through the joint efforts of three EU funded Projects (CoolLIFE (LIFE21-CET-COOLING Grant ID: 101075405), SAPHEA (Horizon Europe Grant agreement ID: 101075510) and Act!onHeat (H2020 Grant ID: 101033706)) it was possible to derive a full-European mapping of financing instruments relevant for Geothermal DHC. Right below, the mapping tool is embedded.
You can also download the excel file and the Status Report to be used offline.

GeoPLASMA-CE
The Central Europe project GeoPLASMA-CE dealt with the shallow geothermal potential in 6 Case Study areas: Walbrzych / Broumow (PL, CZ), Krakow (PL), Vogtland / W-Bohemia (DE), Vienna (AT), Bratislava – Hainburg – Kittsee (SK, AT) and Ljubljana (SL).
The project launched a web-platform including a Web GIS, Glossary and a Knowledge platform.
Geo-DH Project
The GeoDH project aimed to overcome the non-technical barriers to the development of Geothermal District heating, specifically by:
- Increasing awareness amongst policy and decision makers from national authorities about the potential of this technology.
- Developing strategies for the simplification of the administrative and regulatory procedures and, in some cases, the filling of regulatory gaps.
- Developing Innovative Financial Models.
- Training technicians, civil servants and decision-makers of regional and local authorities in order to provide the technical background necessary to approve and support projects.
