The diagrams illustrate the process by which geothermal energy is harnessed to generate electricity.
Overall, the process consists of five distinct stages where in cold water is transformed into steam, ultimately yielding electrical energy for use.
Initially, cold water is introduced into the system via an injection well, descending to a depth of 4.5 kilometers where it reaches the geothermal zone, characterized by hot rocks that elevate the water’s temperature. Upon absorption of heat, the water transitions into a heated state and is subsequently pumped up through the production well. In this stage, the now heated water transforms into steam, which is a critical component in the electricity generation process.
The steam generated from the heated water then powers a turbine, effectively converting thermal energy into mechanical energy. This turbine is connected to a generator, which is responsible for producing electricity. Following this, the steam is cooled in a condenser, reverting back to cold water, which is then reinjected into the geothermal reservoir, thereby completing the cycle and ensuring the sustainability of the geothermal energy production process.
