CDGP - Data Center for Deep Geothermal Energy
Project
The LabEx G-EAU-THERMIE PROFONDE
is a research program on deep geothermal energy founded by the French Ministry of Research and Education in the framework
of the "Laboratories of Excellence" initiative.
CDGP is set to archive the high quality data collected in the Upper Rhine Graben geothermal sites and
to distribute them to the scientific community for R&D activities, taking Intellectual Property Rights into account.
The Interdisciplinary Thematic Institute for Geosciences for the Energy System Transition – ITI GeoT succeeds the LabEx for a new 2021-2028 period.
CDGP is part of EPOS-IP Anthropogenic Hazards and provides Episodes. An Episode is a comprehensive data description of a geophysical (e.g. deformation) process, induced or triggered by technological activity, which under certain circumstances can become hazardous for people, infrastructure and environment.
CDGP in involved in the Geo-INQUIRE project.
Data available on the platform
Data distributed by the CDGP consist of seismological and hydraulic data that have been acquired during stimulation or circulation phases at Soultz-sous-Forêts pilot plant. They are gathered into "episodes": time-correlated collections of geophysical, technological and other relevant geo-data over a geothermal area. Other geophysical data (gravimetric, magnetic, InSAR) will be also inserted into the datastore in the future.
News and Agenda
Events & Presentations
At the end of 2025, ITI GeoT organized the Symposium on Anthropogenic Hazards in Strasbourg. An oral presentation on the CDGP was given.
In November, the CDGP team attended 3rd Geo-INQUIRE Project Annual Meeting 2025 in Naples, Italy
In October 2025, the CDGP team participated in the European Geothermal Congress in Zurich. An oral presentation on the CDGP was given.
Read (in french) the Lettre de l'EOST (October), which mentions the mid-term evaluation of ITI-GeoT
