How geothermal power generation works

1

3

Two wells are drilled into granitic rock

Steam produced is fed through a heat exchanger

2

4

Water is pumped from the deepest well where temperatures are expected to be about 180C

Extracted heat is converted into electricity

5

Water is reinjected into the ground to pick up more heat in a continuous cycle
