The paper illustrates the realization of an experimental real-scale energy tunnel prototype in the tunnel under construction of the Turin Metro Line 1 South Extension. The aim is to test a new concept of energy segment (Enertun) that will be here described by outlining advantages, possible configurations and applications. A comprehensive view of the different phases needed for the installation of the prototype will be given together with the description of its main components. An illustrative test performed at the site is also described and discussed by showing the amount of heat that can be exploited from the ground.
