Geothermal energy and storage

This course introduces the fundamental concepts needed to understand the genesis and functioning of geothermal reservoirs.

Initially, the different types of geothermal energy, from very low-energy to high-energy geothermal energy for electricity production, are discussed in detail, with real-life case studies. A global overview is provided to assess the energy potential of geothermal resources.

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

The problem 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 interactions between stored fluids and surrounding rocks, will be highlighted, with the aim of considering the feasibility and durability of these storage devices.

The aim of this course is 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 will provide basic knowledge of mass and heat transfer, and of the interactions between fluids and rocks, which are essential for the operation of geothermal reservoirs and storage tanks.

In-depth knowledge of reservoir geology.

Continuous assessment with two tests.
