Task 39 ”Polymers for Solar Thermal Applications“ of the International Energy Agency’s Solar Heating and Cooling Programme (IEA SHC) was a joint endeavor by polymer and solar thermal experts from industry and research. It started in 2006 with a variety of studies on polymeric materials’ suitability for the application in solar heating components. Investigations on novel designs that allow for alternative materials were elaborated as well as accompanying studies on the cost-reduction potential resulting from the efficient combination of material and product design.

IEA SHC Task 39: Position Paper
June 2015 - PDF 0.28MB
This position paper describes the current state of the art for polymeric materials in solar thermal applications, shows the potential of polymers in solar thermal applications, and encourages further R&D activities. The major advantages of using polymeric materials in solar thermal systems are economical aspects, especially when taking into account the increasing solar thermal market and increasing raw material prices for metals. Although the cost of materials per mass unit might often be put forward as a major advantage of polymers relative to metals in conventional collectors, the entire picture is more complex. Many successful applications of polymeric materials in solar thermal systems that perform equally well or better in terms of conventional energy savings, reduction of materials, as well as production, transport, installation and/or end-user costs have been demonstrated.

In order to estimate the future demand for polymeric materials in solar thermal systems, the Institute of Polymeric Materials and Testing at JKU Linz (AT) and the AEE-Institute for Sustainable Technologies in Gleisdorf (AT) analyzed global and European scenarios that aim at a 100% renewable energy supply by 2050. Those scenarios were compared to European market scenarios established by ESTIF (European Solar Thermal Industry Federation). Based on these scenarios the resulting polymeric material demand until 2050 was calculated, and the results were compared to the potential development of the total global oil reserves and plastics production.

Talking about polymeric collectors, the reduction of production costs is one main argument for the use of polymeric materials instead of metals. This cost advantage can be split into two categories: lower material costs of the polymeric materials on the one hand and lower manufacturing costs on the other hand. Comparing just the prices for raw materials per kilogram is not sufficient and only little can be said about the saving potential of polymeric materials. In the here presented manner, using some assumptions, a detailed analysis of the cost effects of polymeric materials for the use in solar thermal applications can be performed.

Polymeric Materials for Solar Thermal Applications
February 2014 - PDF 0.18MB
One of the greatest challenges of the 21st century is to secure sustainable and save energy supply and to considerably reduce CO2 emissions and the potential serious consequences of climate change. The challenging goals with regard to the contributions of renewable energies cannot be obtained without a considerable growth of the solar thermal markets worldwide. Therefore, reliable, efficient and cost-competitive system components are required in large quantities. Today solar thermal collectors mainly consist of glass and metals whereas especially market prices for metals are subject to big fluctuations. These issues demand the introduction of new materials, of which polymers seem to have a strong preference with regard to mass-production techniques, new design freedom, cost- and weight reduction.

--- Der vermehrte Einsatz von Kunststoffen eröffnet nicht nur ein erhebliches Kostensenkungspotential, sondern durch die Designfreiheit auch die Chance, Solarthermie ‚neu‘ zu denken. Raum für die Arbeit an innovativen Lösungsansätzen bietet das 2006 ins Leben gerufene Projekt „Polymeric Materials for Solar Thermal Applications“ (IEA SHC Task 39). Nunmehr in ihrer zweiten Phase (Laufzeit 2010 – 2014), dient es als internationale Plattform für die Vernetzung von Experten aus Forschung und Industrie der Solarthermie- und Kunststoffbranche. Ziel ist die Entwicklung zukunftsweisender solarthermischer Systeme, die durch den Einsatz geeigneter Polymermaterialien und die damit verbundene mögliche Massenproduktion einfach und kostengünstig herzustellen sind ...

ISBN: 978-3-527-33246-5
--- Bridging the gap between basic science and technological applications, this is the first book devoted to polymers for solar thermal applications. Clearly divided into three major parts, the contributions are written by experts on solar thermal applications and polymer scientists alike. The first part explains the fundamentals of solar thermal energy especially for representatives of the plastics industry and researchers. Part two then goes on to provide introductory information on polymeric materials and processing for solar thermal experts. The third part combines both of these fields, discussing the potential of polymeric materials in solar thermal applications, as well as demands on durability, design and building integration. With its emphasis on applications, this monograph is relevant for researchers at universities and developers in commercial labs.

--- Die allseits propagierten CO2-Einsparungsziele sind ohne eine gewaltige Steigerung der Verwendung der Solarthermie nicht zu schaffen. Dazu werden zuverlässige, leistungsfähige und kostengünstige Anlagenkomponenten in enormer Stückzahl gebraucht. Da Massenproduktion eine Domäne der Kunststofftechnik ist, ergeben sich speziell in diesem Bereich neue Möglichkeiten für das Kollektor- und Speicherdesign. Damit beschäftigt sich seit drei Jahren die Task 39 ...
