ABSTRACT:
Disclosed is a system for transporting geothermal hot water taken up at an underground bottom portion of a geothermal production well up to the ground surface, efficiently with a loss suppressed to minimum of the energy possessed by the geothermal hot water, which comprises a downhole pump disposed at an underground bottom portion of the geothermal production well for taking up and pressurizing the geothermal hot water and a rotary separation two-phase flow turbine adapted to be driven by the transported geothermal hot water, the downhole pump being adapted to be driven by the rotary separation two-phase flow turbine. Also disclosed is a system for utilization of underground geothermal hot water, which comprises a downhole pump disposed at an underground bottom portion of a geothermal production well and a rotary separation two-phase flow turbine for pressurizing geothermal hot water taken up and supplied thereto by the downhole pump and supplying pressurized geothermal hot water to a direct contact heat exchanger so as to generate power through the medium of a low boiling-temperature medium, while at the same time separating and supplying steam to a steam turbine to generate power, whereby a power generation by a binary cycle is carried out.
