Geothermal Energy and Storage

This learning unit introduces the fundamental concepts needed to understand the formation and operation of geothermal reservoirs.

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

The EU will then focus on several topics specific to geothermal energy, such as mass and heat transfer mechanisms in reservoirs. These will be discussed and illustrated using real-world examples through 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 examining applications such as the underground storage of CO2, heat, or energy. The influence of the mechanical properties of reservoir rocks, as well as the interactions between the stored fluids and the surrounding 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 relevant applications of geothermal energy and underground storage. In addition to a general overview of the underlying concepts and associated technologies, this course unit will provide basic knowledge in the areas of mass and heat transfer and fluid-rock interactions, which are critical to the operation of geothermal reservoirs and storage reservoirs.

In-depth knowledge of reservoir geology.
