Objective
Detailed feasibility study for the exploitation of a geothermal resource to heat the runway and buildings at Milano-Linate Airport. The study is to examine the application of geothermal heat to reduce Airport blocks due to frost-snow and fog which close the Airport for 400 H/Y. This project already supported by the Commission (see GE/447/86/IT) would be widened on the following : analysis of new seismic lines-simulation, water bearing strata -analysis, temperature gradient, economics and well drilling programmes.
According to the study, interseasonal storage/destorage of geothermal heat can be technically possible in Linate Milano Airport. Using the doublet system, 300 m3/h of water could be stored at 25 deg. C in the shallow aquifer during summer. Thus water could be repumped during water to supply heat to the airport heating system. The nominal efficiency of the aquifer storage facility would be close to 70%. The choice of the aquifer at 60-70 m depth is a compromise between drilling cost and heat losses in the shallower aquifers.
The study "Evaluation of the underground geothermal and hydrogeological resources" includes : - an evaluation of the existing shallow fresh water aquifer in Linate.
- a simulation for a" multiplet system consisting of two production wells and two injection wells.
- a simulation to determine the best system to store the interseasonal heat by means of aquifer
storage. An additional seismic interpretation has carried out.
