The European Spallation Source for Neutron Research (ESS) in Lund, Sweden, has chosen German utility E.ON as its energy partner throughout the research facility’s lifespan until 2065.

E.ON is to provide cooling, compressed air and the recovery of surplus energy as well as the supply of renewable energy to the large-scale research facility.

The facility requires different types of cooling, which simultaneously generates heat for Lund's district heating network.
