Anti-icing using the heat recovered in the Lagoscuro tunnel

In the context of promoting local energy sources with low environmental impact, energy geostructures are more and more being explored. This paper will describe an example of a technological system able to achieve the anti-icing of the motorway pavement through the exploitation of heat from the adjacent tunnel. Taking advantage of the current motorway refurbishment plan fostered by Autostrade per l'Italia (ASPI) and the activities planned for the Lagoscuro tunnel, located along the A26 motorway in the Genova province, the opportunity for geothermal energy exploitation is being tested in a full-scale prototype. The details of the experimental site setup will be revealed together with the characteristics of the pavement anti-icing solution.
