Read more about the SDH-Project.
By end of December 2010, four SDH projects in the region of Styria, two in Carinthia and one each in Upper Austria and Salzburg were approved by Klimafonds, a federal funding authority.
Allbohus Fastighets AB, a municipal housing company, has built a roof-integrated solar collector field of 350 m2 on a multi-family building in Vislanda, Sweden, which is connected to the district heating network via a pre-fabricated sub-station.
Thanks to the participation of AIRU (Italian District Heating Association) and Ambiente Italia in the SDHtake-off project, Italy could be able to install, in a couple of years, the first solar thermal plants connected to district heating networks.
The results have convinced the sceptics: The interest in large solar thermal systems between 100 and 2,000 m2 of collector area has been enormous in Austria.
The main objective of this Task is to assist in a strong and sustainable market development of large solar district heating and cooling systems. The systems can include seasonal storages and/or heat pumps/chillers.
Ritter XL Solar is finalist of the German Industry’s Innovation Award 2010 („Innovationspreis der Deutschen Wirtschaft“).
Jan-Olof Dalenbäck from CIT Energy Management AB presents the Micro Analysis Study ‘Success Factors in Solar District Heating’, which was prepared in the frame of the IEE SDHtake-off project.
In 1996, the Eon Hanse Wärme GmbH built up a local heating network supported by a solar system. With the knowledge gained in this period, Eon decided to reconstruct the storage tank by putting a new steel storage in the old concrete foundation.
The largest solar district hot water project in the world is being built in Riyadh, Saudi Arabia for the University for Women Project. The collectors built from the Austrian company GreenoneTec, with a gross surface of 10 m² should supply the campus with heat. The company based in St.Veit upgraded the capacity of production line. Large-surface collectors are only a small share in the production.
Austria’s climate and energy fund supports solar plants of 100 up to 2000 m² collector are at 40% of invest.
In Denmark happens in those years a veritable boom in connecting large solar thermal plants in combination with district heating and CHP. In addition to the already installed capacity of 80,000 m², new plants in Ringkøbing with 15,000 m² and in Jægerspris with 10,000 m² have just been taken into service.
