ABSTRACT:
A system is disclosed for generating energy from a geothermal heat source. The system includes a fluid injection system configured for injecting fluid into a subterranean formation and a fluid extraction system configured for extracting fluid from the subterranean formation after being heated by the formation. The system further includes a heat transformer configured to receive a first fluid heated by the geothermal heat source at a first temperature and adapted to heat a second fluid to a second temperature via a series of chemical reactions. Furthermore, the system includes an energy generation unit configured to receive heated the second fluid at the second temperature from the heat transformer to increase the temperature of a third fluid which is used to generate energy.
