Accelerator-based research facilities use a lot of energy. ESS’s yearly power requirement has been estimated at approximately 250 GWh. This is the equivalent of a medium-sized paper mill or another major industry.

The excess heat that arises in the facility will also be able to be reused. ESS AB is working together with Lunds Energikoncernen AB ad E.On to find solutions for reusing excess heat in the local district heating system.
Compared to other accelerator-based laboratories, ESS will both use less energy and act to ensure the used energy is not ventilated directly into the atmosphere via cooling towers.
