The present innovation focuses on a method for cleaning up groundwater containing polluting substances having a density of less than 1 g/cm3, such as hydrocarbons. This proposition presents a novel method for removing the layer of floating contaminants based on skimming technology. The method consists in heating the contaminated saturated area until the required temperature is reached, for a time sufficient to reduce the viscosity of the contaminants constituting the floating layer. Skimming technology focuses on the accurate extraction of this floating layer. The present invention aims to combine the use of solar energy for heating the contaminants present in the floating layer of the saturated area, with the skimming method. This aims to optimize the treatment time of the saturated area by heating the contaminants, thus increasing their mobility in order to facilitate their extraction by skimming.

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.
