Energietübbing is the registered trademark of a component for the development of geothermal heat through mechanically constructed (i.e. with a tunnel boring machine , TBM) tunnel structures. The thermal energy obtained in this way can be used for heating and air conditioning purposes in the operating systems belonging to the tunnel or in buildings standing on the surface (near the tunnel). The energy segment can also be used for sewers to extract heat from the sewage.

Description of the technology

In the energy segment, the structural component segment is used as a heat exchanger. The name energy tubbing is derived from the words " energy " and "tubbing" and is to be understood analogously to energy piles or energy fleece, in which a component is used energetically in addition to its static function. The principle of energy tubbing is comparable to tunnel thermal energy , which activates the tunnel shell of conventionally driven tunnels (with shotcrete construction ) as a heat exchanger.

In a pilot project as part of the construction of the new Lower Inn Valley Railway, a 54 m long section in the Jenbach municipality was equipped with energy segments. From the 2010/2011 heating period onwards, this is to supply a company building in the Jenbach community with thermal energy.
