Geothermal energy is heat that is generated within the Earth. The small-scale geothermal wellhead power generation system that has been developed by Toshiba ESS generates power from geothermal resources with outputs ranging from 1MW to 20MW. There must be water resources available to inject steam to spin turbines to create electricity. The geothermal power generation, however, has typical two weak points: one is that the conventional geothermal power generation can only be used in the high-temperature hydrothermal fields near active volcanoes and the other is that the small-scale geothermal power generation systems are rarely available until the present. After the suction, the hot water (brine) superheats an organic fluid (R134a) in a Rankine cycle and, then, is injected back underground. Utility-scale geothermal power plants in the United States use either steam power or a binary cycle to generate electricity. However, the electricity generated by the geothermal resources only contributes to 0.2% of the whole electricity supply. Small-scale geothermal power plants have the potential for widespread application, but achieving cost effectiveness in small plant sizes presents The small-scale geothermal wellhead power generation system that has been developed by Toshiba ESS generates power from geothermal resources with outputs ranging from 1MW to 20MW.
