The diagram below illustrates how geothermal energy is used to generate electricity.
Overall, there are five distinct stages in the process of electricity production from geothermal power. Beginning with the injection of cold water underground and concluding with electricity generation by a turbine-driven generator.
At first, cold water is pumped through a pipeline approximately 4,5km long into the injection well. Here, the water flows through the geothermal zone rich in hot rocks, where the high temperatures from these rock layers heat the water. This stage transforms the coldwater into hot water, preparing it for the subsequent steps in the electricity generation cycle.
After that, the hot water is directed into the production well, where it is pumped to the condenser. Here, the water is converted into steam and directed into the turbine to generate electricity. As the turbine spins, it activates the generator, producing electricity. The electricity generated by the generator is then distributed through the electrical grids. This process not only facilitates efficient electricity production but also remains environmentally friendly, as geothermal energy is a renewable, clean, and stable energy source.
