Learning outcomes of the learning unit
At the end of the course, the student will have a strong basic skill in geothermy. He will be able to:
- be familiar with the main characteristics of geothermal systems;
- make adequate conceptual choices in function of the local energy demand and local geological and hydrogeological conditions;
- collect and organise the needed data for a first assessment and then a feasibility study of the geothermal system;
- calculate basic feasibility aspects of a deep as well as of a shallow geothermal system;
- detect advantages and drawbacks in the choice of an site for geothermal use;
- assess / calculate the mid- and long-term behaviour of a geothermal system in function of the undeground characteristics;
- assess possible impacts on the groundwater resources of a geothermal system.
Prerequisite knowledge and skills
Basic knowledge and understanding of geology and hydrogeology.
Elementary notions of physics (essentially thermodynamics) and chemistry.
No official prerequesite course is compulsory.
Planned learning activities and teaching methods
The course is composed of "ex-cathedra" lectures (see content above).
Practicalwork/exercise (30h) consists in a comparative study of the different geothermal systems in one given site and for a given specific energy demand (i.e. on the basis of geological, hydrogeological, geomechanical and thermal basic data, each group of students must prepare concurrent projects).
Mode of delivery (face to face, distance learning, hybrid learning)
Face-to-face for theory teaching.
In groups of 2 for practical work.
Organisational adjustments related to the current health context
Some video recordings (mp4) will be available on the eCampus platform. Either it will be ppt commented with 'off voice' over and the visible pointer, or it will be recorded classes (podcasts).
If, and only if, the health context requires it, the modifications below may be applied.
Each group is preparing an urban geothermal project. Each group must record a commented powerpoint (or video), with an mp4 export, to be uploaded on eCampus min 24 hours before the exam.
On the day of the exam, an individual oral remote interview by lifesize will be organized to ask more precise questions to each student about the geothermal project. All students of a group will pass sequentially before doing the same for the next group.
We will ask the students to bring a white sheet of paper and a black marker to show us a diagram/schema via the camera to explain/illustrate what they have to say.
Recommended or required readings
A pdf copy of transparents and different publications will be made available on eCampus.
For the shallow geothermy with open systems, it could be useful to check chapter 11 of the following book: Dassargues, A. 2018. Hydrogeology: groundwater science and engineering. Taylor & Francis CRC Press, 472p.
Assessment methods and criteria
Below you will find information on the evaluation methods planned for in-person and remote exams as well as those planned for hybrid sessions. Depending on how the health crisis evolves, the chosen method will be communicated to you no later than one month before the start of the exam session.
Any session :
- In-person
oral exam
- Remote
oral exam
- If evaluation in "hybrid"
preferred in-person
Additional information:
Oral exam consists in a short 'professional' ppt presentation of the main results from the practical work, then questions by the professors acting as 'stake-holders' of the geothermal operation ...
A good knowledge and a perfect command of the fundamentals from all the concerned topics of this geothermy course are indeed needed for being able to provide adequate answers.

Organizational remarks
The course will be given during the 2nd semester. The schedule and the room should be checked on CELCAT.
