The TEMPOTemperature Optimisation for Low Temperature District Heating across Europeproject develops technical innovations that enables district heating networks to operate at lower temperatures. By decreasing the temperature in the systems, it reduces heat losses and allows a higher share of renewable and excess heat to be used as heat sources. The use of these heat sources will be crucial to adapt current district heating systems and create new ones suitable for a sustainable energy system.

Six technological innovations that contribute to minimising the temperature in networks and enables a cost-efficient implementation of low temperature networks will undergo final development in TEMPO. Each of the innovations can bring value to most district heating networks individually. However, the main strength of this project lies in the combination of the individual technologies into solution packages for dedicated application areas. Three solution packages customised to three different application areas, that together covers 90% of the district heating market in Europe, will be tested in selected representative demos:

  • New urban low temperature district heating networks
  • New rural low temperature district heating networks
  • Existing high temperature district heating networks

Additionally, TEMPO will develop innovative approaches to consumer empowerment enabled by digital solutions. The project will also develop new business models and demonstrate their replication potential for the roll-out of sustainable and economically viable district heating networks across the EU.
