As a part of Fortum's vision of a future Solar Economy, a feasibility study of a Solar
District Heating facility was conducted. The focus of this study was to determine the
technical, economic and environmental potential of a Solar District Heating facility,
combined with a seasonal thermal storage, in the district heating network in
Three different cases have been studied. The cases differ on the size of the available
land area, on what type of storage technology utilized and if excess heat from
different production facilities in the network is included or not. The results indicate
that it is technically possible to implement a Solar District Heating facility in
Stockholm, no obvious limitations in the network has been identified. The thermal
storage should preferably be charged throughout the year and be discharged during
December to March.
The economic results indicate that none of the studied cases are economically feasible
without any subsidies, increased revenues or other reductions of initial investment
costs. The most economically beneficial system configuration was to utilize a smaller
land area for solar collector installations, include excess heat from local production
facilities and to utilize existing rock caverns and infrastructure in the area.
The Solar District Heating facility could decrease the climate impact and the net
primary energy use compared to the production of a biofuel production facility, but a
further study is needed.
