Lecture 09 Energy Transition - Geothermal Energy

Geothermal Energy: Renewable Energy with constant power output and a maximum of full load hours / capacity factors: Principle and conversion processes of geothermal energy use. Geological parameters. Costs for exploration, set-up and operation. Application and comparison of cycles and processes: Carnot, OCR, Flash, Double Flash, Binary, Kalina. Examples from Iceland and the US. Exercise at the end of the lecture.

All lectures:
7. Wind Energy: Historical and actual development of wind power conversion.
Extractable power from the wind. Parameters of wind energy: Height, pressure, temperature, density. Weibull- and Rayleigh-distribution of wind velocity.
Theoretical conversion efficiency of wind power conversion, Betz efficiency. Types of wind power converters, tip speed ratio, cost, complementarity, software tool, literature.

This is a great youtube clip... thanks for uploading...

Sir why temperature decrease when heat rejected in kalina cycle as phase change process should happen at const temperature

Hi, if i have a well that is 3000 m deep offshore and a bottomhole temperature of 124 degC, Expecting to produce 15000 barrels/day of water. what would be expected fluid temperature at the wellhead? Just an estimation will be fine, what is the expected temperature difference (heat loss) from the bottom to the surface

Guten Tag.
Werden bis zu der Prüfung noch alle Themenfelder in Videos abgedeckt?
Und wenn nicht, sind die nicht besprochenen Themen Klausurrelevant?
Vielen Dank schon einmal.
Grüße Robin

Hello,
Will there be an exercise video for Geothermal Energy? In Exercise 9a Q2 Where does the W_heater req = 25.21 GW required for the natural gas mass calculation come from? Should it be 2.877MW?
