Course description
In the field of renewable energies, the course is devoted to the geothermal resources. The program will highlight the origin and dynamics of geothermal resources and fluids and the main exploration and exploitation technologies aimed to their use. It will consider both high and low enthalpy systems in terms of origin, behavior, potential and real uses, environmental and economic benefits and impacts.
Expected Learning Outcomes
At the end of the course students should know the main principles related to high and low enthalpy geothermal energy systems, the main techniques of the geothermal exploration and the technologies for their exploitation in several environmental, territorial and geological contexts. Through practical exercises and field trips students will be involved in the processes of resources estimation and in the design and sizing of the geothermal plants.
Pre-requirements
Intermediate knowledge of the main natural physical phenomena, fundamental of mathematics and thermo-physics.
Course topics
INTRODUCTION TO GEOTHERMAL ENERGY Fundamentals of geology, the structure of the Earth, origin of geothermal resources, geothermal gradient and geothermal anomalies, the thermal properties of the ground, field methods to assess ground thermal properties. Geothermal exploration techniques.
FUNDAMENTALS OF HYDROGEOLOGY Introduction to groundwater and hydrodynamics in porous media. Water wells and wells design. Unsaturated zone and aquifers properties. Heat propagation in the aquifers.
LOW ENTHALPY GEOTHERMAL SYSTEM Open-loop geothermal systems. Closed-loop geothermal systems. Thermal Response Test, Heat pumps and plants. Legal, technical and economic elements. Sustainability and assessment of resources. Environmental impact and implementation with particular focus on urban areas.
HIGH ENTHALPY GEOTHERMAL SYSTEM Geothermal reservoirs (water and vapour dominated geothermal systems, hot dry rock systems). Deep geothermal exploration techniques. Uses of high enthalpy geothermal systems. Estimation, sustainability and environmental impact. Economic highlights in the energy world market.
