Geothermal energy

Written by  Dušan Majcin | Published in: Geothermics

The methods of the geothermal energy sources parameters determination and their application in the region of Slovakia.

 

Depth distribution of the reservoir temperature 160 °C for effective application of the binary cycle power plant technology in Slovakia and adjacent areas. The depths of the isothermal surface are plotted with the isoline step of 500 m.
