Acquis d'apprentissage (objectifs d'apprentissage) de l'unité d'enseignement

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.

Savoirs et compétences prérequis

Basic knowledge and understanding of geology and hydrogeology.
Elementary notions of physics (essentially thermodynamics) and chemistry.
No official prerequesite course is compulsory.

Activités d'apprentissage prévues et méthodes d'enseignement

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 d'enseignement (présentiel ; enseignement à distance)

Face-to-face for theory teaching.
In groups of 2 for practical work.

Lectures recommandées ou obligatoires et notes de cours

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.

Modalités d'évaluation et critères

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.
