The lecture „Geothermal Energy – Geological Fundamentals and Applications“ conveys the fundamental knowledge necessary to understand Geothermics and current options of geothermal energy utilization. The lecture is held in English.
In addition to presenting general academic knowledge of Geothermics, special emphasis is put on geothermal regimes of the earth, potential and technically accessible geothermal resources, and current options of exploration and utilization. This is presented in regard to “shallow” geothermal systems (down to approx. 300 m below ground), as well as deep geothermal systems (down to several kilometres of depth). Generally, the point of view is that of the geosciences, but select topics of exploration, reservoir and heat engineering are included.
One special teaching goal is an understanding of the entire energy flow as pertaining to various utilization scenarios. Finally, potential environmental impacts, as well as the importance of geothermal energy for the Energy Turnaround, in accordance with Sustainable Development Goal SDG 7, are adressed.
As for the practical exercises, students are presented with case studies, involving, on the one hand, the qualitative assessment of geothermal potential, including potential problems, on the other hand, uncomplicated quantitative methods of estimating reservoir productivity, energy flow, and use efficiency, under various given conditions.
