Recommended Qualifications -
Learning Outcomes a) Geothermal Resource Identification and Development
After the successful participation in the course Geothermal Resource Identification and Development the students are able to:
  • identify and characterize the geothermal prospects and the techniques for drilling wells into geothermal formations to extract hot fluids.
b) Geothermal Applications
After the successful participation in the course Geothermal Applications the students are able to:
  • discuss the general concepts of geothermal power plants
  • define the main characteristics of the geothermal fluids used in space or district heating
  • describe the main features of the absorption cycles used for air conditioning and industrial refrigeration in geothermal applications
  • discuss the factors influencing greenhouse climate.
Contents a) Geothermal Resource Identification and Development
  • Geology of geothermal regions: the earth and its atmosphere; active geothermal regions; model of a hydrothermal geothermal resource and other types of geothermal resources; exploration strategies and techniques; objectives and phases of an exploration program; synthesis and interpretation.
  • Geothermal well drilling: site preparation and drilling equipment; drilling operations; safety precautions.
  • Reservoir engineering: reservoir and well flow; well testing; calcite scaling in well casings; reservoir modelling and simulation.
b) Geothermal Applications
  • Electricity generation
    • technical features of plant options: atmospheric and condensing exhaust conventional steam turbines; binary plant; biphase rotary separatorturbo-alternator.
    • well-head generating units: economic considerations regarding small geothermal plants.
  • Space and district heating: resource considerations; space heating (or cooling) needs; hot water collection and transmission system; equipment selection; economical and environmental considerations; tariffs; integrated uses.
  • Space cooling: air conditioning; commercial refrigeration; absorption research; materials.
  • Greenhouse heating: energy aspects of protected crop cultivation; characteristics of heat consumption; technical solutions for geothermal greenhouse heating; geothermal greenhouse heating installations; factors influencing the choice ofheating installation; final considerations.
Media Black board and beamer; introductory class meetings, power point presentations, discussions, practical exercises, case studies in groups; formal &interactive.
