Geothermal Energy (ENP130)

This course offers an in-depth exploration of geothermal energy, covering the scientific principles, technological advancements, and practical applications of both shallow and deep geothermal systems. Students will gain a thorough understanding of geothermal resource assessment, extraction technologies, and the integration of geothermal energy into the existing energy infrastructure. The curriculum emphasizes sustainable practices, environmental considerations, and the economic aspects of geothermal energy utilization.

This course offers the students with petroleum specialization an opportunity to connect their acquired knowledge in drilling and well construction to renewable and sustainable geothermal energy applications. Access to UiS living lab, i.e. the energy central which is providing the campus with geothermal heating and cooling energy, provides students with opportunity to work with real world systems and practical design considerations.

NB! This is an elective course and may be cancelled if fewer than 10 students are enrolled by August 20th.

The course covers the following key areas:

Fundamentals of Geothermal Energy

• The Earth’s heat flow.
• Heat transfer mechanisms in the subsurface: conduction, convection, and advection.
• Geological and hydrogeological principles affecting geothermal energy potential.
• Shallow vs. deep geothermal systems.

Shallow Geothermal Systems

• Closed-loop systems: Borehole heat exchangers (BHE), horizontal collectors
• Open-loop systems: Well systems and direct groundwater utilization.
• Geothermal energy storage in aquifers Thermal Energy Storage (ATES) and Borehole Thermal Energy Storage (BTES)

Deep Geothermal Energy Systems

• High-enthalpy geothermal reservoirs and their role in electricity generation.
• Enhanced Geothermal Systems (EGS): Hydraulic fracturing and deep heat extraction.
• Drilling technologies and well completion for deep geothermal projects.
• Case studies and global applications.

Geothermal Exploration and Resource Assessment

• Geological, geophysical, and hydrogeological site investigations.
• Thermal response tests (TRT) and ground conductivity testing.
• Modeling of shallow and deep geothermal applications.

Design and Engineering of Geothermal Systems

• Borehole heat exchanger design: Depth, spacing, and configuration.
• Heat transfer fluids: Properties, selection criteria, and environmental impact.
• Geotechnical considerations for shallow geothermal systems.

Environmental and Risk Assessment in Geothermal Energy

• Groundwater protection and regulations.
• Hadrochemical interactions and effect on geothermal performance.
• Induced seismicity and land subsidence.

Throughout the course, students will analyse case studies and practical examples to deepen their understanding of how geothermal resources can contribute to the global energy. Python programming will facilitate the analysis. The course is designed to equip students with a robust understanding of geothermal energy systems, preparing them for careers in the energy sector, environmental engineering, and energy policy.

Upon successful completion of this course, students will be able to:

1. Apply Engineering Methods to explore, assess, and develop geothermal resources.
2. Evaluate the environmental risks associated to geothermal energy projects, including induced seismicity and groundwater contamination.
3. Apply theoretical knowledge to real-world cases, evaluating the success and limitations of geothermal projects across different geologic settings.
4. Work effectively in multidisciplinary teams to design and propose solutions for the exploration, extraction, and utilization of geothermal resources.
5. Communicate geothermal concepts and findings to both specialists and non-specialists.

Skills

By the end of the course, students will have the following skills:

1. Ability to apply engineering principles to geothermal resource assessment and management.
2. Modeling and simulation skills to predict geothermal reservoir behavior and optimize production.
3. Competence for assessing environmental risks related to geothermal exploitation.
4. Ability to design and manage geothermal projects, including exploration, drilling, power generation, and heat distribution.
5. Verbal and written communication skills for geothermal projects.
6. Analytical skills for evaluating the feasibility and impact of geothermal projects

The course will have 2 hours of lecture and 2 hours of tutorial per week.

Hands-on Python programming will be used throughout the course to illustrate concepts and facilitate data analysis and modelling.
