Final Project Report: Heat Highway

Heat Highway - NEFI

The use of industrial waste heat is essential for the decarbonisation of heat supply. While the electricity transmission grid connects many generation, storage and consumption units, current options for waste heat injection and interregional exchange are limited. Heat Highway is therefore investigating interregional heat transfer networks (HTN), which combines four areas: industrial waste heat and other sustainable sources, district heating networks, industrial process heat sinks and storage. These HTNs connect consumption centers and industrial sites, by travelling through areas with other heat sources and sinks. The project reduces risks by including many supply and demand nodes and creating innovative business models. The concept will go far beyond the state of the art in terms of the number of actors, interregionality and networking.
