A matrix method to select the more suitable extraction technology for the Campi Flegrei geothermal area (Italy)

This paper presents a Selection Matrix to compare the doublet plant technology proposed in the area of Campi Flegrei (Italy) to a deep borehole heat exchanger power plant. The Selection Matrix is composed of several indices with weight for the calculation of the final score of the project. The aim of the work is to provide an evaluation instrument of two different geothermal power plants, as well as to highlight that the results of the evaluation depends on the weight the decision maker assigns to the indices, considering the specific features of the territory where the plant is located.
