Heat Highway-Interregional heat transmission networks to enable industrial waste heat usage and fossil-free industry

While the electricity transmission grid is connecting many generation, storage and consumption units on an interregional scale, similar options for heat networks are limited. Heat Highway investigates interregional heat transmission networks (HTN), focusing on the utilization of multiple waste heat sources. Heat Highway will go far beyond the state of the art in terms of number of players involved, interregionality and interaction.

Ausgangssituation

While there is a supra-regional electricity grid connecting many generating, storage and consumption units, district heating networks (DHN) are locally limited infrastructures. Currently, around 2,400 district heating networks exist in Austria.

Projektinhalt

Heat Highway will use these innovations to elaborate two 100 km long HTN in Austria and push three sections towards realization: it prepares KPC investment funding applications for the sections “Zentralraum” and “Linz” and initializes next steps and stakeholder participation in Styria. The investigations in four follower regions ensure replicability.

Projektverlauf

Heat Highway aims to develop a multi-level toolbox for optimizing the HTN implementation and operation, anticipate industrial waste heat potential from current and breakthrough processes in a decarbonization scenario, develop and prototype a cost-effective pipe system to significantly reduce the investment costs in HTN, and  set up a 3D simulation based “virtual HTN demonstrator” for showcasing the feasibility of HTN systems despite their complexity.

"Fernwärme-Übertragungsnetze sind neben den großen Strom- und Gasnetzen die „dritte Dimension“, die in einem nachhaltigen, hocheffizienten, exergieorientierten Energiesystem fehlt ."
