Solar energy for district heating

Solar district heating (SDH) plants are a very large scale application of the solar thermal technology.

These plants are integrated into local district heating networks for both residential and industrial use. During warmer periods they can totally replace other sources, usually fossil fuels, used for heat supply. Thanks to the developments in large scale thermal storage it isnow also possible to store heat in summer for winter use. Solar thermal can also meet a share of the heating demand during the winter.

The economic and environmental benefits derived from the acknowledged reliability of this solar thermal application, allied to the technical expertise gained over decades, have contributed to the growing interest in its commercial operation. Currently there are many plants in operation in Sweden, Denmark, Germany and Austria.
