  • Hot dry rock generation system
    Patent number: 8661818
    Abstract: A hot dry rock generation system, having: a recharge well that is formed from the ground to an underground hot dry rock into which a heat carrier streams through the recharge well; a production well that is formed from the underground hot dry rock from which the heated heat carrier is streams through the production well; a power generation plant that converts the thermal energy of the heat carrier streaming out of, into electric energy; a collecting tank that stores the heat carrier discharged from the power generation plant; a sealing water pump that sucks the heat carrier collected in the collecting tank and makes the heat carrier stream into the recharge well, whereby the hot dry rock generation system is provided with a heat exchanger into which the heat carrier streaming out of the production well streams.
