What and why did we win?

The award in the category “New Scheme” is given to a new type of district energy system with high ambition and aspiration – and which have achieved a high level of energy efficiency.

That’s a good description of Cool DH and the low-temperature district heating (LTDH) demo site in Lund, Sweden.

The LTDH grid in Brunnshög is the world’s largest and has been in use since 2019 – and is still evolving. The grid is based on fossil free energy from recovered waste heat from research facilities nearby. Many new technologies are introduced in the production, distribution and use of the heat resulting in less energy losses and cheaper energy for the customers. Making sure that the residual heat from the nearby research facility MAX IV, and soon ESS, come to good use.

What’s next?

As Brunnshög grows, more and more clients are connected and new and innovative uses of heat has been implemented. A tramway connects Brunnshög to the center of Lund and all tram stops will have shelters that will be heated by the LTDH system. Bike ways and sidewalks will be heated to make them free of snow and ice in the winter, amongst many other ideas and plans.

As the same time as the demo sites in Sweden and Denmark develops the people behind the project Cool DH gather insights, results and lessons learned from the work and cooperation. Register to our newsletter and you won’t miss a thing.
