Germany: “Performance-based incentives for all solar thermal plants”

Submitted by Baerbel Epp on November 11, 2016
In spring 2015, Germany´s Federal Office for Economic Affairs and Export Control (BAFA) introduced a performance-based incentive for solar heating as an alternative to the scheme offering incentives based on collector area. Recently published statistics have shown the new programme to grant higher financial support for about one-third of the currently funded projects. The others still receive funding from the previously established scheme.

Denmark/Germany: Consumer-Owned Utilities Spearhead Energy Market Transformation

Submitted by Baerbel Epp on November 2, 2016
Webinar SpeakersSolar district heating is becoming increasingly attractive to small towns and municipalities which are looking for energy independence and stable heat prices, a trend which was discussed at length during the October webinar by the International Solar Energy Society (ISES). Entitled Renewable district heating – Small local grids and cooperative utilities, it offered an opportunity for German and Danish experts to present successful case studies, underline the political frame conditions which foster renewable integration into district heating and explain the advantages of cooperatives (recording available online). The photo shows the experts participating in this first webinar of a three-part series coordinated by Riccardo Battisti, Head of EU Project SmartReFlex: Per Alex Sørensen and Per Kristensen from Denmark as well as Oliver Miedaner from German Solites (from left). The second webinar – Think big: Design rules and monitoring results of solar district heating systems – will be organised in cooperation with solarthermalworld.org and is scheduled for 6 December (online registration). 
 

France: Is This The New Solar District Heating Country?

Submitted by Baerbel Epp on October 26, 2016
France District Heating ResultsAfter France had become involved in a couple of EU-supported projects as a newcomer, the country is now ready for take-off in the solar district heating (SDH) market. Monitoring data from the first two French pilot plants show performance to be quite good and the systems to be highly reliable. The chart depicting the performance of the 458 m2 evacuated tube collector field in Balma-Gramont was presented by Fabrice Renaud, Research Engineer in the R&D centre Cylergie at the French group Engie, during the 4th International Solar District Heating Conference in Billund, Denmark. There is also a new strategy document being devised to advance the development of SDH in the French region of Auvergne – Rhône-Alpes.

IEA SHC Task 51: German Summer School Educates Students on Solar Urban Planning

Submitted by Baerbel Epp on October 18, 2016
Summer School BerlinThe summer school called City in Transition (Stadt im Wandel) ended with a public presentation of the project designs from four student groups on Monday, 26 September, in Berlin, Germany (see photo). During the previous week, students from different fields and German universities had developed a master plan for solar-optimised buildings in an area of Berlin’s Adlershof district. ”We educated students on how to combine town planning and solar energy usage,” explained Tanja Siems, one of the organisers of the summer school and Head of the Institute of Urban Design & Studies, Faculty of Architecture and Civil Engineering of the University of Wuppertal, Germany. Several experts from the IEA Solar Heating and Cooling programme’s Task 51, Solar Energy in Urban Planning, had supported the summer school as tutors or evaluated the final presentations.

Solar District Heating: Good Performances All Over Europe

Submitted by Baerbel Epp on October 4, 2016
Crailsheim Monitoring ResultsThe 4th International Solar District Heating (SDH) Conference, which had been organised under the auspices of Horizon 2020 project SDHp2m…from Policy to Market on 21/22 September 2016 in Denmark, showed the importance of analysing real-life monitoring data from European SDH plants, with one conference session (Advanced SDH systems II) dedicated exclusively to the topic. These kinds of comparisons enable an understanding of the actual performance of such large collector fields and offer an opportunity for optimising power output and for creating best-practice examples of new plants. For example, the chart displays ten years’ worth of monitoring data from the German plant in Crailsheim, which has met solar yield expectations.

Denmark: “Solar District Heating is a Big Part of Our Industry’s future”

Submitted by Baerbel Epp on September 29, 2016
While the solar thermal industry has had a difficult time in several EU countries, the solar district heating (SDH) community is still growing: 180 participants from the EU, South Korea and China attended the 4th International Solar District Heating Conference, which was held at quite the peculiar location this year – Denmark’s Legoland – and was organised under the auspices of the Horizon 2020 project SDHp2m…from Policy to Market. The introductory session of the conference was really inspiring. Thomas Pauschinger, Project Coordinator of SDHp2m, underlined how Denmark’s construction of plants in the 100 MW range was proof of the country’s solar thermal strategy of “think big”. Impressive results, even more so if one takes the statement by Kim Behnke, Deputy Director General of Dansk Fjernvarme, the Danish District Heating Association, into account that “the Danish solar dream started just ten years ago”. Denmark’s solar installations have become so famous that they have even been turned into brick models at Legoland. The photo shows the 13 MW solar field in Braedstrup, Denmark.

Germany: First Record-Size Solar District Heating Plant in 11 Years

Submitted by Baerbel Epp on September 27, 2016
Senftenberg GermanyFriday, 23 September 2016, was the inauguration date for the now largest solar thermal collector field in Germany. Since August, 8,300 m² of vacuum tube collectors (5.8 MWth) set up in the town of Senftenberg, 140 km south of Berlin, have been feeding energy into the municipality’s district heating network. The previously largest field since 2005 – a 7,100 m² flat plate collector installation (5.1 MWth) – is located in the southern German town of Crailsheim. The new Senftenberg solar field was designed, manufactured and implemented by German system integrator Ritter XL Solar. The 1,680 collectors, the heat transfer unit and around 6,600 m of pipework were installed within record time: All in all, the project took only six months. The general contractor for the EUR 4.5 million investment was Berlin-based E&G Energiebau, which had received support from the Integral Project, the company responsible for sizing and integrating the solar heat into the existing network.

District heating: “The industry is very optimistic about its future prospects”

Submitted by Baerbel Epp on September 23, 2016

Ralf Roman SchmidtDistrict heating has a long history in Scandinavia: The international symposium on district heating was launched there in 1987. In the meantime, the technology has reached the global stage and the 15th International Symposium on District Heating and Cooling was the first one supported by the IEA District Heating and Cooling programme (IEA DHC). Dr Ralf Roman Schmidt had been invited to speak at this two-day conference held in South Korea in September and attended by more than 200 people. The research engineer from the AIT, Austrian Institute of Technology, is about to become Austria’s alternate country representative within the IEA DHC.
