TEMPO

10/2017 – 09/2021 (4 years)

5.0 m. EUR

The TEMPO project 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:

• Supervision ICT platform
• Visualisation tools
• Smart DHC controller
• Innovative pipe system
• Optimisation of building installations
• Decentralised buffer tanks

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 are customised to three different application areas, that 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

The project is structured into the following parts:

• Final innovation development for solution package integration
• Vattenfall demonstrator
• Enerpipe demonstrator
• A2A demonstrator
• Evaluation und knowhow transfer
• Replication and Business models
• Dissemination and communication
• Project management

Solites is responsible for the Vattenfall demonstrator and for the individual monitoring concepts in all three demonstrators. Therefore, a comparable evaluation is possible. In a simulation study for the Enerpipe demonstrator Solites will furthermore examine the ecological and economic potential of the decentralised buffer concept in small DHC systems.

Complete solutions packages are developed to minimise the temperature in networks and enables a cost-efficient implementation of low temperature networks. These packages are tested in three representative demo networks.

The monitoring of the demo networks which realised the technological innovations will be the basis for the established dissemination and communication plan. This will implicate the transfer of improving innovations to other district heating networks.

The reports will be available on the project website directly after finalisation.
