Sustainability and green

ESS will not just be one of the world’s most modern research facilities; it will also be one of the most sustainable and energy-intelligent.

The objective is that the facility will use a minimum amount of energy, that all energy will derive from renewable energy sources and that a maximum amount of residual energy is recycled. Each area has concrete goals that represent the conditions for how the facility is designed and constructed.

Energy consumption – a major challenge

The major challenge is energy consumption. Consequently, an energy inventory is conducted twice annually to monitor future energy consumption.

The latest results point to a total energy consumption of 265 GWh. Despite the large figures, it may be compared with the original plan for ESS, which would have required 610 GWh per year.

Excess heat to be recycled

A key aspect of the sustainability efforts is the utilization of excess heat. Some of the heat will be used in the district-heating network, which is expected to replace other forms of heating and thus be capable of cutting carbon dioxide emissions in Lund.

To optimize heat recovery, the facility’s cooling system will operate using three temperature levels: – 30 ° C, 55 ° C and 80 ° C, where the highest temperature can be transferred directly to a district heating network. For the lower temperatures, ESS has a unique potential to set a new standard for how energy can be recycled. It is hoped that it will prove possible to utilize the energy for commercial food production.

However, the most important and most long-term environmental and sustainability effect of ESS is the future application of the research results permitted by the facility.
