Work is in hand to construct Sweden’s largest District Heating (DH) system based on concentrating solar technology. The 3,000 m2 field of parabolic trough collectors (1.5 MWth) is part of a EUR 1.6 million demonstration project.
Initiator and developer of the solar district heating plant is Absolicon Solar Collector, manufacturer of the T160 covered parabolic trough collector and the supplier of complete production lines for this sort of equipment. To efficiently transfer the heat to the DH network, Absolicon has selected SWEP to deliver a number of its high-end B649 Brazed Plate Heat Exchangers.
Absolicon is co-financing the construction of the demonstration plant along with the Swedish Energy Agency and will sell solar heat to Härnösand Energi & Miljö (known as HEMAB), the owner and operator of the town of Härnösand’s DH network, 400 kilometres north of Stockholm. Another partner is Umeå University, which is carrying out third-party monitoring and validation together with the Research Institutes of Sweden (RISE).
