Innovative Energy Efficiency Solution at Arlanda Airport
Arlanda Airport, a major hub for Scandinavian air traffic, has successfully optimized its energy efficiency, achieving annual energy savings of 19 GWh, equivalent to the energy used by 2,000 average-sized Swedish single-family houses. The key to this success was the use of an underground thermal water storage system, which utilizes the largest known aquifer located under the airport. The system, provided by Alfa Laval, stores hot water during the summer for use in the winter and vice versa, eliminating the need for chillers, heat pumps, and fossil fuels.

The system, provided by Alfa Laval, stores hot water during the summer for use in the winter and vice versa, eliminating the need for chillers, heat pumps, and fossil fuels. Since its implementation in 2009, the system has not only achieved the projected energy savings but also reduced CO2 emissions by nearly 7,000 tonnes annually. This project serves as a model for energy efficiency and has earned recognition for its significant contribution to reducing environmental impact.
