Gmunden HT Link


Project Description

The Gmunden cement plant has a waste heat potential of 10 MWth at 400°C. For this reason, the approach of using heat all year round is being pursued. The aim of the present project is therefore to implement heat recovery in the cement works and to transfer the heat at the highest possible temperature level via a 1.5 km long district heating line via public land to industrial heat consumers. This approach is breaking new ground due to the high temperatures. As the site is in a tourist area near a lake, the highest possible environmental and safety standards must be met. Another challenge is the year-round supply of heat: cement works in Austria are shut down for several weeks in winter. A solution should therefore be analyzed in which the security of supply is achieved via an innovative heat storage system. The Energieinstitut accompanies the technical research with techno-economic, business, legal and socio-economic analyses.
