5th Expert Meeting of IEA ES Task 39 - Large Thermal Energy Storages for District Heating

15. - 16. September 2022
Hjulmagervej 55 - 9000 Aalborg - Denmark, Aalborg, DK

The content of the two-day event includes expert discussions, workshops and project presentations on large-scale thermal energy storage systems.


AEE INTEC supported and hosted by the local company Aalborg CSP.

Content Description

Large-scale thermal energy storages make it possible to increase the use of renewables in existing energy supply systems, achieve supply independence and security, and enable the coupling of individual energy sectors, for example through Power2Heat solutions.

In four subtasks (ST), the international experts will address the following issues:

  • ST A: Application scenarios, assessment of concepts and integration aspects
  • ST B: Components and material database
  • ST C: Round robin simulations
  • ST D: Knowledge base for decision makers

AEE - Institute for Sustainable Technologies (AEE INTEC) was founded in 1988 and is today one of the leading European institutes for applied research in the field of renewable energy and resource efficiency. In the three target group areas "Buildings", "Cities & Networks" and "Industrial Systems" as well as three technological working groups "Renewable Energies", "Thermal Storages" and "Water and Process Technologies", the range of R&D projects carried out extends from basic research projects to the implementation of demonstration plants.


The program of the Task 39 meeting will be two days of discussion along the Subtasks of the Task 39 and an excursion to the pit thermal energy storage in Dronninglund.

More information can be found in the tables (see downloads).


Target Audience

The target audience is very broad and ranges from plant designers for thermal energy supply, material manufacturers and installation companies of large scale thermal energy storages or individual components thereof, to simulation experts for the evaluation and optimization and the distribution of such plants.

Participant Information

The event will take place following the International Smart Energy Systems Conference in Aalborg, Denmark.
