Description
Large scale solar district heating has increased fast recently and is a commercial industry
in Denmark with over 100 systems. Pit storage with high solar fraction exist in several of
these systems. Economic factors in Sweden are not as good as in Denmark, but many
scenarios show increased competition for biomass with higher prices and thus better
viability for solar. Sweden’s potential for solar district heating was shown in a recent
study by the Swedish Energy Agency to be 0.17 – 6.0 TWh depending on assumptions.
This project will start with a list of locations shown by this study as most viable. More
detailed techno-economic studies of solar district heat will be made for three towns from
this list that have the right conditions for a pit storage that will also be used with a heat
pump during low electricity prices. Finally, results from these case studies will be
extrapolated by using spatial analysis to estimate the number of systems that could be
realistic to install in Sweden.
