Austria: Optimising of Large-scale Collector Fields

Submitted by Baerbel Epp on January 6, 2016
Hydraulic SchemesOne key aspect of the energy and cost optimisation of large-scale collector fields (called arrays in this news) is collector array hydraulics. Optimal connection is achieved when (1) the costs and length of the connecting pipes is small, (2) the pressure drop over the entire array is low and (3) there is homogeneous mass flow distribution across the entire field. “Homogeneous mass flow reduces power losses in the circuit, avoids inefficient pump operation and prevents local stagnation,” explains Philip Ohnewein. The researcher at Austrian institute AEE INTEC managed the four-year project ParaSol (2011 to 2014), which – among other things – analysed the advantages and disadvantages of different hydraulic designs of large collector arrays of several hundreds to several thousands of panels. The results were also discussed and published as part of Task 45, Large Systems: Large Solar Heating/Cooling Systems, Seasonal Storage, Heat Pumps, of the IEA Solar Heating and Cooling Programme in a two-page info leaflet and a 44-page technical document (attached to this article). 
 

Solar Cooling: Results Diagram Directs Stakeholders to Content of Interest

Submitted by Baerbel Epp on December 29, 2015
Task 48The best solar research results are of little use if they are not distributed and known to stakeholders from the industry, planning departments or public authorities involved in the related field work. This becomes an even more important point if the aim of the research is to “assist with the developing of a strong and sustainable market”. One example: Task 48 (Quality Assurance & Support Measures for Solar Cooling Systems) under the auspices of the IEA Solar Heating and Cooling programme. Between October 2011 and March 2015, a very dynamic group of 30 solar cooling experts teamed up to work on a wide range of topics. As many as 180 person months of research were at the disposal of the programme’s coordinators, which created a lot of interesting output. The cooling specialists accepted and met the challenge by presenting results in a clear structure on the above-shown diagram. The so-called Task 48 Results Diagram could serve as a best-practice model for other international research projects.

Submitted by Baerbel Epp on December 7, 2015
SHC2015Two continents meet in Istanbul, in a metropolis of 15 million. More than 230 researchers and industry representatives from five continents used this strategic spot for their participation in SHC2015, a high-level conference which took place at the beginning of December and focused on solar heating and cooling technologies as well as their related markets. The three-day event organised by the IEA Solar Heating and Cooling Programme in cooperation with the German company PSE and the European Solar Thermal Industry Federation (ESTIF) presented a mix of technological innovations, the latest research results, service tools for planners and designers of complex solar heating and cooling installations, and it offered a lot of room for discussions on market and technology developments from different countries and regions. This news piece will highlight some of the key aspects of the conference and will be followed by a number of solarthermalworld.org articles over the coming weeks, each with their own special focus.

IEA SHC Task 51: Urban Planners Know Little about Solar Energy Potential

Submitted by Baerbel Epp on November 3, 2015
IEA SHC Task 51During IEA SHC Task 51, Solar Energy in Urban Planning, the project partners evaluated the legal, process and education issues of solar in urban planning across the twelve member countries. What they found was: Planners and architects know little about the opportunities of solar energy usage. Solar energy in urban planning is also rarely a topic during university courses for architects or urban planners. The photo shows participants of the latest Task 51 meeting visiting a big PV installation. The meeting was held on the French island of Réunion from 28 September to 2 October. The task is about all types of solar energy.

IEA SHC: Start of International Research Network on GW-Sized Solar Thermal Plants

Submitted by Baerbel Epp on October 23, 2015
The IEA’s solar heating and cooling programme has begun its research activities on solar thermal systems of gigawatt size. Scientists, industry representatives and utilities have been invited to participate in a definition workshop for a new task in the Austrian city of Graz on 5 November 2015. Sabine Putz, COO and R&D Manager at S.O.L.I.D., an Austrian large-scale turnkey system supplier, has proposed a four-year research programme entitled Large Scale Solar District Heating and Cooling Systems, which aims at studying economic, engineering and quality factors influencing solar district heating and cooling systems above 3.5 MW and up to GW size. 
 

IEA SHC: Industry Invited to Join Research Community for Lower Solar Heat Costs

Submitted by Baerbel Epp on October 12, 2015
TASK 54Driving down the costs of solar thermal systems is not only about cheaper collector production. In fact, post-production processes, such as sales, installation and maintenance account for up to 50 % of the price the end customer will have to pay. The new IEA SHC Task 54, Price Reduction of Solar Thermal Systems, wants to investigate those factors and find ways to reduce system costs. The kick-off meeting on 21 to 22 October will be hosted by Fraunhofer ISE in Freiburg, Germany. Researchers and industry representatives from all over the world have been invited to participate. The task spans over three years and includes on average two two-day experts meetings per year.

Submitted by Baerbel Epp on October 5, 2015
Arcon-Sunmark ChileIndustry participation is key for the research work of IEA’s Solar Heating and Cooling Programme. Hence, the researchers of Task 49, Solar Heat Integration in Industrial Processes, used the last meeting in France in mid-September to hold a one-day workshop dedicated to Solar Heat Integration in Industrial Processes (SHIP) in cooperation with French start-up Energy Service Company Sunti. In Montpellier, SHIP 2015 gathered experts from the solar process heat collector industry, researchers, government and non-government organisations, as well as representatives for potential customers. Customers were particularly interested in the economic feasibility of systems. A wide variety of plants and operation data was presented. The photo shows the installation of the world’s largest solar process heat plant at the Gaby copper mine in Chile. Each year, the plant saves 6,500 tonnes of diesel, which would have had to be transported by 250 trucks through the desert.

Above all, the workshop provided a platform for presenting the first outcomes of the international research cooperation TASK 53 entitled New Generation Solar Cooling & Heating Systems, which was launched in March 2014, will end in 2017 and involves 10 countries, some from outside Europe (see the attached introductory presentation). 
 

IEA SHC Task 42: Latent Heat Storage Has Huge Potential in the Long Run

Submitted by Baerbel Epp on September 25, 2015
IEA SHC Task 42In their position paper published in August 2015, the scientists of IEA SHC Task 42 (Compact Thermal Energy Storage) summed up the key results of their work between 2009 and 2015. Operating agent Matthias Rommel sees huge potential for latent heat and sorption materials in the long run – in seasonal solar heat storage for small and medium applications, as well as in the building sector. So-called smart grids will also require more heat storage units when devices such as heat pumps and co-generation plants are based on electricity grid requirements. Rommel views the definition of measurement standards for PCM materials as one of the task’s big achievements, which will help in material development. Furthermore, a research group from German research institute ZAE Bayern has performed a first cost estimate of compact heat storage technologies.
