Risk mitigation in decarbonization of urban heating networks through grid temperature reductions and flexibility use
Many urban district heating networks are mainly based on natural gas-based combined heat and power plants. To secure and decarbonise their heat supply, significant amounts of alternative heat sources are needed such as heat pumps, waste heat, solar and geothermal energy.
The aim of the DeRiskDH project is to solve the challenges associated with the integration of those alternative heat sources. Challenges are in the optimisation of the building stock with regard to return temperatures and flexibilities, in network hydraulics, bidirectional operation, the integration of seasonal storage and in the inclusion of consumers and business models. Concrete solutions are demonstrated and tested in Vienna, Graz, Linz, Salzburg, and Klagenfurt.
Funding tool
This project is supported with the funds from the Climate and Energy Fund and implemented in the framework of the RTI-initiative “Flagship region Energy”.
