Lithuania: Can Solar Thermal Beat Low Biomass Heat Prices?

Submitted by Baerbel Epp on August 14, 2017
Lithuania District HeatingWith biomass prices on the rise, solar district heating could become profitable in Lithuania. But without investment grants, payback periods were still too long, it said in the conclusion of a 2015 SDH market study by LEI, the Lithuanian Energy Institute (see the attached document in Lithuanian). The photo shows the country’s first SDH system set up in 2011. Installed on the roof of the boiler house, it preheats water for a wood chip boiler in the district heating station of Dūkštas, a town in eastern Lithuania. The demonstration unit with 82 m² of vacuum tube collectors received funding from international organisations.

Europe: 23 New and Upgraded Solar District Heating Plants of 190 MWth Start Operation in 2015

Submitted by Baerbel Epp on April 5, 2016
District Heating EuropeAs in previous years, Denmark remained the country dominating Europe’s solar district heating market. Twenty of the 23 new and upgraded district heating plants in Europe above 350 kWth (500 m²) from the statistics compiled by Jan-Olof Dalenbäck from the Chalmers University of Technology, Sweden, went into operation in Denmark – whereas Austria, Italy and Sweden had only one each to show for. Dalenbäck’s database shows 211 large-scale district heating plants currently in operation, with combined output at 708 MW (1.01 million m²). This means that only every fourth district heating plant in Europe uses solar energy compared to the 5,400 district heating systems a database from Swedish Halmstad University lists from across the EU-27. The map shows 2,188 cities with 2,445 larger district heating systems. The highest plant densities can be found in Denmark, Poland, the Czech Republic and Slovakia.

France: Third Solar District Heating Conference Call for Paper

Submitted by Baerbel Epp on January 3, 2015
BalmaAfter Denmark and Germany, it will now be France’s turn to host the Solar District Heating Conference. Researchers, as well as representatives from municipality utilities and solar thermal system suppliers will meet in Toulouse on 17 and 18 June 2015 to discuss international case studies, new business models and marketing strategies. The two-day event will consist of a mix of panel discussions, presentations by industry experts and site visits. In Toulouse, conference participants can visit the first French solar district heating plant, which is located in the eco-district of Balma and boasts 458 m² of vacuum tube collectors on a shade structure on top of a parking lot (see photo).

Europe: Online Database on Large-Scale Solar Heating Plants

Submitted by Baerbel Epp on November 18, 2014
District Heating per CountryThe database on Europe’s largest solar heating plants, which can be found on the EU project SDHplus website, dates back to 1997. In the meantime, it has grown to 131 solar heating plants totalling a collector area of 586,000 m² (410 MWth). The first plants included in the database were installed in 1979. 124 of 131 systems are solar heating plants, most of them for district heating (particularly those in Denmark, Sweden, Germany, Austria, Poland and France), but also for large buildings, industrial use and other applications, whereas seven are cooling installations. The database contains "close to 100 % of all plants which have a minimum thermal output of 700 kW and started operating until the end of 2013,” says Jan-Olof Dalenbäck from the Chalmers University of Technology, who is in charge of updating the database as part of the SDHplus project. Eleven of these systems, with a joint output of 22 MW, have been shut down by now. The pie chart shows the installed collector area of district heating systems broken down by country.

Call for Abstracts: Second International Solar District Heating Conference in Hamburg, Germany

Submitted by Baerbel Epp on January 17, 2014
The second International Solar District Heating Conference invites market actors and experts on the topic to Hamburg, Germany, on 3 and 4 June 2014 to offer an exchange of experiences, as well as networking opportunities at an international level. The SDH 2014 Call for Abstracts has just commenced: Solar professionals are welcome to submit their presentation proposals for the conference before 14 February 2014. The photo shows participants of last year’s conference having joined the technical tour around the so-called Bo01 Sustainable City Development area at the Western Harbour in Malmö, Sweden, at which solar heat is fed into the city’s district heating network. The first conference on solar district heating in April 2013 sparked great international interest and attracted 120 participants from 19 countries.

Norway: Solar Collectors Support District Heating

Submitted by Baerbel Epp on February 11, 2013

In November 2012, the Norwegian power supplier Akershus Energi celebrated the inauguration of its new 13,000 m² solar district heating plant in the town of Lillestrøm close to Oslo. Built by Danish company Sunmark, it is the largest solar thermal plant in Norway to date. The plant is to deliver 20 to 30 % of the heat required by the district heating network during the summer time. All year round, it is to produce 4.2 GWh of solar heat (323 kWh/m² of collector area), which equals little more than 3 % of the network’s total heat supply.

Europe: SDHplus Gathers Experts and Newcomers to Solar District Heating

Submitted by Baerbel Epp on April 5, 2012

 SDH Logo Just after the Intelligent Energy Europe (IEE) project SDHtake-off will have ended in June 2012, there will be a follow-up project called SDHplus. Six new countries will join it: Spain, France, Lithuania, Croatia, Poland and Slovenia. Experienced partners from the former SDHtake-off project will help them promote solar district heating by launching awareness-raising campaigns and assessing the potential of their heat supply network. SDHplus comes with a budget of EUR 1.8 million from the IEE fund and will run over three years.
