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.

IEA SHC Task 50: Lighting Industry Explores Contracting Solutions

Submitted by Baerbel Epp on October 3, 2016
Now!LED technology has greatly changed the face of the lighting market: In just a few years, lighting systems have become twice as efficient and half as expensive. These changes have resulted in a large but often untapped cost- and energy-saving potential in commercial buildings. The research in Task 50 of the IEA Solar Heating and Cooling programme, Advanced Lighting Solutions for Retrofitting Buildings, has shown that the lighting industry is increasingly exploring opportunities for the use of contracting instead of leasing solutions to convince customers of retrofits. According to Marc Fontoynont, Professor at the Department of Energy Performance at Aalborg University, Denmark, and subtask leader of Market and Policies, there is a growing number of specialised companies which offer contracting models for lighting solutions, such as Austrian manufacturer Zumtobel has done with its contracting plan Now! (see chart). All in all, these contracting solutions are less complex than the ones for heat.

Germany: International Conference on Heat Access in Southern Africa

Submitted by Baerbel Epp on October 1, 2016
Soltrain TeamMerging three individual conferences into the International Conference on Solar Technologies & Hybrid Mini Grids to Improve Energy Access was rewarded with a satisfying number of attendees visiting the latter. According to the organisers, 185 experts from 38 countries from all corners of the globe met in the small town of Bad Hersfeld near Frankfurt, Germany, in mid-September 2016 to talk about all the technology and market requirements for increasing solar deployment in developing countries. The conference schedule was, of course, fairly focused on photovoltaics, but Southern Africa was well represented, as experts from the partner countries of SOLTRAIN (Southern African Solar Thermal Training and Demonstration Initiative) presented their work during the event (see photo).

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.

IEA SHC: Cost Reduction Analysis Workshops at German University of Stuttgart

Submitted by Baerbel Epp on September 8, 2016
Task54 Brussels WorkshopSystem cost reduction is one of the most urgent challenges of the solar thermal sector, especially in central Europe. The aim of Task 54 of the IEA Solar Heating and Cooling Programme, Price Reduction of Solar Thermal Systems, is to lower solar heat prices by up to 40 %. Germany’s main scientific contributions to the task have come from the two research projects KoST and TEWIsol, which have been co-funded by the German Federal Ministry for Economic Affairs and Energy. The corresponding Task 54 meeting will take place in Stuttgart on 6/7 October (see the attached programme) in conjunction with a workshop on 5 October to present and discuss KoST and TEWIsol (12 p.m. to 4 p.m.; held in German). The photo shows the Task 54 workshop organised in collaboration with the European Solar Thermal Industry Federation in Brussels in May 2016.

Intersolar Europe 2017, Munich

Submitted by Baerbel Epp on September 6, 2016
Intersolar Europe 2017 will take place from 31 May to 2 June 2017 in Munich, Germany. The Exhibition is one of the world's largest solar technology trade fairs and the number one meeting point for everyone in the solar industry. Intersolar focuses on the Photovoltaic and Solar Thermal branches. In 2016 Intersolar Europe and ees Europe, the continent's largest exhibition for batteries and energy storage systems, played host to more than 1,000 exhibitors and drew in around 43,000 visitors from 160 countries.

Germany: 2Power PVT Modules Supply Power and Heat from Same Roof Space

Submitted by Baerbel Epp on September 2, 2016
PA-IDPVT Modules combine the generation of solar heat and solar electricity. For many years, products have entered and disappeared from the market without leaving much of a trace. German company PA-ID has installed around 8,000 2Power panels, at almost 500 project sites. The 2Power elements consist of standard PV laminates with a polymer heat exchanger at the back, enclosed by insulation. In July, a group toured to the so far largest installation with 121 kWth and 44 kWel in Unterliederbach, a suburb of the German city of Frankfurt.

IEA SHC: Coordinating Thermal Energy Storage Research Worldwide

Submitted by Baerbel Epp on August 30, 2016
The key to the decarbonisation of the energy sector is new compact storage technology: It will require much R&D to develop market-ready products based on new storage designs with phase change and thermochemical materials (PCMs and TCMs). One strategy is to combine resources within international research programmes – to create platforms unhindered by national borders or scientific disciplines, such as the joint task Material and Component Development for Thermal Energy Storage planned within the IEA Technology Collaboration Programmes. Its two future operating agents, Wim van Helden (left) from Austrian AEE INTEC for the IEA Solar Heating and Cooling Programme and Andreas Hauer from the German Bavarian Center for Applied Energy Research (ZAE Bayern) for the IEA Energy Conservation through Energy Storage (ECES) programme, invite all interested researchers to Vienna, Austria, to attend the second Task Definition Meeting on 15 and 16 September 2016.
