Defining the Shallow Geothermal Heat-Exchange Potential for a Lower Fluvial Plain of the Central Apennines: The Metauro Valley (Marche Region, Italy)

In this work we assessed the shallow geothermal heat-exchange potential of a fluvial plain Central Apennines, lower Metauro Valley, where about 90,000 people live. Publicly available geognostic drilling data from Italian Seismic Microzonation studies have been exploited together with hydrogeological and thermophysical properties main geological formations area. These averaged over firsts 100 m subsoil to define thermal conductivity, specific heat extraction rates ground establish area (expressed in MWh y?1). The investigation revealed that is mainly controlled by bedrock lithotypes saturated conditions sedimentary infill. A general increase mapped moving coast, higher infill thicknesses found, towards inland carbonate approaches surface. investigated Valley mostly between ~9.0 ~10 y?1 average depth be drilled supply standard domestic power demand 4.0 kW ~96 (ranging 82 125 all valley). This emphasizes represent huge database for best assessment throughout regions, which can addressed implementation heating cooling through vertical closed-loop borehole exchanger systems coupled pumps.
