Sustainable heating and cooling for cities

Over the past decades, Stockholm and Sweden have reduced CO2 emissions and increased resource efficiency, while maintaining high and sustainable economic growth. A major part of the recipe for success has been the development of the infrastructure for district heating and cooling. The district heating and cooling networks cover the Greater Stockholm Area. A set of large production plants, where waste and biomass are utilized to simultaneously produce heat and electricity, form the basis of district heating supply. In addition, sea water, chillers and a range of large heat pumps supply the district cooling network. All in all, these systems make for a virtually unmatched large scale solution to the challenge of sustainability, cost efficiency and security of supply.
