Hydrothermal Systems, Geothermal Doublets | SpringerLink

Abstract. Hydrothermal systems use the thermal energy of an aqueous fluid at greater depths. Depending on the heat content of the fluid, systems with high enthalpy can be distinguished from low enthalpy systems. High enthalpy systems produce electrical power directly from hot steam or from a high-temperature two-phase fluid.
