International Summer School in Thermogeology, taking place from 3rd to 8th July 2023 in Ljubljana / Slovenia


Topic: Advances in developing geothermal resources for heating, cooling and electricity production


Within this summer school, attendees will use geothermal concepts to investigate and couple available geothermal potential with various technologies, regarding if it is shallow or deep geothermal.

At the end of the course, the participants should:

-          Explain geothermal concepts and exploration methods used to characterize geothermal resources.

-          Explain various existing technologies for geothermal use, cascade use, and heat or cold production from the ground

-          Explain interactions between heat and flow fields in the subsurface and their change during the project lifetime.

-          Describe the concept of sustainable exploitation of renewable resources and proper project development.

-          Be able to illustratively present the student project prepared during the course.

The course is available for

-          PhD and postdoc students interested in geothermal energy use and impacts

-          MSc students interested in geothermal

-          Professionals who deal with any aspect of geothermal within their work.


-   EEA Grants supported project INFO-GEOTHERMAL - Supporting efficient cascade use of geothermal energy by unlocking official and public information
-   COST action project CA18219 Geothermal-DHC - Research network for including geothermal technologies into decarbonized heating and cooling grids
-   Geological Survey of Slovenia (GeoZS)
-   Faculty of Natural Sciences and Engineering in Ljubljana (NTF UL)
-   Iceland School of Energy (ISE)


Day 1: Geothermal concepts & student conference
Day 2: Field trip to NE Slovenia (a heat pump factory, a well drilling site, a spa with cascade use and a pilot geothermal power plant on a re-worked abandoned oil and gas borehole (project Si-Geo-Electricity))
Day 3: Advanced technologies in using geothermal and project economics
Day 4: New opportunities in direct use and high temperature resources & field work exercises
Day 5: Environmental issues, heat and power grids & preparation of student projects
Day 6: Preparation and presentation of student projects & final exam

Attendance at the summer school is free, including the travel during the 1-day field trip. Trainers and trainees must sign the attendance list each day.
Attendees should provide for their own travel arrangements and accommodation, but they can apply for a grant to cover part of their costs.
EEA Grants project INFO-GEOTHERMAL will provide for part of the travel and accommodation costs for 4 trainees from E and SE European countries and 4 trainers. It provides a lump sum of 600 € per scholarship. Project INFO-GEOTHERMAL will also provide coffee breaks and light lunch during the summer school, printing of the student conference abstract book, and costs of the field trip.
COST Project CA18219 Geothermal-DHC will provide for part of the travel and accommodation costs for up to 11 trainees and 4 trainers and part of LOS. It may cover up to 300 € of your long-distance travel expenses (based on invoices) and a daily allowance rate of 100 € per day for a maximum duration of 7 days (no proof needed) for trainees and 150 € for trainers. For further terms and conditions as well as instructions please see COST Annotated rules, Annex 1, A1 3.1. Travel reimbursement rules. Cancellation insurance is an eligible expense included in long-distance travel expenses. The Geothermal-DHC Action MC reserves all rights to reduce the daily allowance rate in case of unforeseen circumstances. In this case, applicants will be informed about possible reductions prior to formal invitations via the eCOST system.


The applications are open until Wednesday 26th of April 2023.
The application should be done following several steps:
1. Create/update your profile on eCOST (
2. Submit your application documents to as unsigned Word documents named LAST NAME first name file type (e.g. RMAN Nina application, RMAN Nina CV).
2) CV with list of publications.
3. Carefully read the COST Annotated rules, Annex 1, A1 3.1. (
4. Opional (in case of interest): Create or update your profile on the Yellow Pages of Geothermal-DHC (

The selection results will be delivered to the applicants by the 20th of May 2023 latest.
We will select trainees trying to reach the following goals:
- up to 30 trainees
- quality of proposed contributions by the trainee & the student conference
- background from at least 3 different thematic groups (e.g. geologists, machine engineers, environmental specialists, social or economy sciences...)
- country balance (at least 3 countries represented)
- at least 4 trainees from ITC countries
- institutional balance (more than one trainee from the same faculty/institution will be selected in exceptional and well justified cases only)
- an average share of at least 40% of each gender, if possible
- priority will be given to trainees who will attend such summer school for the first time.
