“…In recent years, an EGS technology has been developed to artificially create a reservoir by hydraulic stimulation, thus enhancing the permeability and fluid saturation of hot dry rock. Such technology is still in the development stage with few pilot plants in operation, but not yet commercialized (Matek, 2016;Mohais et al, 2016). Other than electricity generation, geothermal energy can be used for various direct heat applications such as space and district heating, geothermal heat pumps, agricultural applications, drying and evaporation processes, heat requirements in animal husbandry, aquaculture, etc.…”
