Now we come to geothermal electricity production via Hot Dry Rock technique (HDRt).
The principle of the Hot Dry Rock technique is shown in this slide. At least two wells have to be drilled to a depth of approximately 4000m. One of the wells is used to press water into the porous rock. Here the water heats up and within the second well it flows up to feed a thermal power unit which produces electricity. The HDRt enlarges the geothermal potential since the places where steam or hot water is found which could be used directly to drive a thermal power plant are very rare.
