Research: EVALUATION OF THE GEOTHERMAL POTENTIAL IN CENTRAL ITALY

My research activity focuses on the evaluation of the geothermal potential in Central Italy. Considering the current global importance of renewable energies, research on geothermal potential in Central Italy is nowadays fundamental and innovative because of its energy possibilities and because of its still underestimated potential. The project intends to standardize and integrate geological, stratigraphic, structural and hydrogeological knowledges, from the peri-Tyrrhenian belt to the Adriatic coast of Central Italy, in order to quantitatively and qualitatively assess deep geothermal resources. Italy, and in particular the central peri-Tyrrhenian belt, offers great geothermal potential, with flow values from 100 to 450 mWatt/m2. Today, the most interesting areas from a geothermal point of view are located in Central-Southern Tuscany, where occur many of the geothermal fields currently in operation (Larderello, Travale/Radicondoli and Monte Amiata - Northern Italy - high enthalpy - ENEL) such as the first geothermal energy field in the world of Larderello, founded in 1904 (Benelli et al., 2008). While the VIGOR project (for medium - low enthalpy fields - shallow and deep ones) exists for Southern Italy. Despite its promising geological-structural configuration and the promising geothermal features, Central Italy does not show systematic, homogeneous and organized studies of the geothermal potential in a single database. The general objective of this project consists in an accurate characterization of geothermal systems in Central Italy, defining the regional circulation model and defining their potential in terms of geothermal energy planning. The target is the development of an unifying and reliable Map of the Geothermal Potential of the area. The specific target of the project consists in the geological, structural, hydrodynamic and thermal characterization of a case study geothermal system and in the definition of the related parameters. GIS database rendering and 3D contour mapping from seismic stratigraphy (reservoir modelling - Petrel) will allow to produce output data necessary for the subsequent 3D Computational Fluid Dynamics modelling. The input dataset on which the research will be based, comes from the public VIDEPI, VIGOR and CNR databases, but will be complemented by data collected during the PhD project such as thermal conductivity values from laboratory data, 3D geological modelling and new field surveys. In some cases, geochemical data will also be collected, with geochemical monitoring of transitional waters. Finally, heat flow, thermal conductivity, gravimetric and magnetotelluric data will be evaluated, which, with the integration of stratigraphic well data and seismic reflection profiles, will allow to detect any inhomogeneity in the distribution of point data of the area considered (DGISSEG-UNMIG Guidelines, 2016).
