Transregional heat transfer grids for industrial waste heat and fossil free industry
While the electricity transmission grid is connecting many production, storage and consumption units at 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 surpasses the state of the art in terms of number of players involved, trans-regionality and interaction. 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.
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.
The chair of Energy Network Technology is responsible for the development of a district heating load flow calculation tool as well as for the investigation of the Styrian use case.
Heat Highway is part of the innovation network NEFI (New Energy for Industry), which is facilitating the energy transition through technology development together with the Austrian industry.
