Geothermal energy and storage

This EU presents the fundamental concepts needed to understand the formation and functioning of geothermal reservoirs.

First, the different types of geothermal energy, from very low energy to high energy geothermal energy for electricity generation, are discussed in detail and examined through real-life case studies. A global overview is provided in order to assess the energy potential of geothermal resources.

The EU will then focus on several points specific to geothermal energy, such as mass and heat transfer mechanisms in reservoirs. These will be addressed and illustrated using real-life cases via numerical modeling. The geological signature of geothermal reservoirs, such as mineral alterations, will also be studied in detail through case studies.

The issue of storage will be addressed by considering applications such as underground storage of CO₂, heat, or energy. The influence of the mechanical properties of reservoir rocks, as well as the interactions between stored fluids and host rocks, will be highlighted in order to assess the feasibility and sustainability of these storage systems.

This course unit aims to provide a general understanding of the highly topical applications of geothermal energy and underground storage. In addition to a general presentation of the underlying concepts and associated technologies, this course unit will provide basic knowledge in the field of mass and heat transfer and in the field of interactions between fluids and rocks, which are predominant in the operation of geothermal reservoirs and storage reservoirs.

In-depth knowledge of reservoir geology.

Continuous assessment consisting of two tests.
