Geothermal energy and storage

This course presents the fundamental concepts for understanding the genesis and functioning of geothermal reservoirs.

First, the different types of geothermal energy, from very low energy to high energy geothermal energy for electricity production are discussed in detail and are the subject of real case studies. An overview on a global scale is proposed in order to evaluate the energy potential of geothermal resources.

The course 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 through 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 the reservoir rocks, as well as the interactions between the stored fluids and the surrounding rocks, will be highlighted in order to consider the feasibility and durability of these storage devices.

This course aims to provide a general knowledge of the very current 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 in the field of mass and heat transfer and in the field of interactions between fluids and rocks, which are important for the operation of geothermal reservoirs and storage tanks.

In-depth knowledge of reservoir geology.
