A geothermal power system includes a pressure exchanger fluid ically coupled to a heat exchanger. A first fluid enters the pressure exchanger at a first inlet, and flows in a first fluid path to a first outlet. The first fluid flows from the first outlet to the heat exchanger, where the first fluid heats a second fluid. The first fluid flows from the heat exchanger to a second inlet of the pressure exchanger. The first fluid flows in a second fluid path through the pressure exchanger to a second outlet. A pressure of the first fluid reduces as the first fluid transits through the pressure exchanger along the first fluid path. A pressure of the first fluid increases as the first fluid transits through the pressure exchanger along the second fluid path. The first fluid flows from the second outlet to a turbine which drives a generator.
