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.  

IEA SHC: 20 Country Profile Analyse Market and Industry Development

Submitted by Baerbel Epp on September 3, 2015
SHC country members“The Renewable Heat Incentive in the United Kingdom has failed to stimulate the market for solar thermal, which continues to contract. There are technical issues in the regulations preventing the use of solar thermal with other renewable heating systems, such as biomass and heat pumps, and the subsidy rate is relatively low compared to the feed-in tariff for solar photovoltaics.” This clear statement was made by Dr Robert Edwards, Director in the Science and Innovation Group at the Department of Energy and Climate Change (DECC). He represents the country in the Executive Committee of the IEA Solar Heating and Cooling (SHC) research programme and delivered an updated country profile of the British solar thermal market in June 2015. As part of its services, the IEA SHC programme publishes updated market profiles of all 20 member countries each year. You will find the list of member countries online and the link to the country profile at the bottom of each country page. The statement by Edwards is part of the latest UK country profile.

IEA SHC: Attractive Solar Process Heat Markets

Submitted by Baerbel Epp on August 28, 2015
fastest growing segmentWhich countries are currently attractive markets for solar process heat? Different sources give different answers to this question. The chart above shows the assessment of the solar industry. More than 30 % of the Austrian solar collector manufacturers in the two surveys in 2012 and 2013 assumed that solar process heat was the fastest-growing segment in their national market. More than every tenth manufacturer in Germany, Mexico and France shared their opinion. The figure in brackets behind the country stands for the number of surveys analysed. Some of the countries, such as Germany, India, Mexico and France, have a support scheme in place which focuses on solar process heat systems.

Turkey: Great Achievements with Little Policy Support

Submitted by Baerbel Epp on August 5, 2015

The interest in technology and market research on the solar heating and cooling sector is growing. The number of countries participating in the IEA Solar Heating and Cooling Programme (SHC) increased significantly over the last two years from 20 to 25 nations. One of the most recent entries was Turkey in 2014, represented by GÜNDER, the Turkish Section of the International Solar Energy Society (ISES). Turkey is the second-largest market after China regarding new solar thermal installations and a gateway to the MENA region, SHC chairman Ken Guthrie praised the new member in a press release this February. Large-scale installations in prisons, hotels and social housing projects are gaining in volume (see photos). The majority of the 20 key solar thermal markets worldwide are now members of the IEA SHC except for India, Brazil, USA, Israel, Greece, Japan and Poland.

IEA SHC: Mutual Recognition of Test and Inspection Reports Saves Industry Costs

Submitted by Baerbel Epp on August 4, 2015

The work of the Global Solar Certification (GSC) Network is expected to continue within the framework of the IEA Solar Heating and Cooling Programme (SHC). The Executive Committee of the IEA SHC approved the set-up of a task definition workshop in Paris on 7 October 2015, in order to establish a new task under the title International Standards & Global Certification. “Collector and system manufacturers selling products in several countries, as well as representatives of certification bodies, test labs and inspectors from all around the world are invited to join the meeting in Paris and become members of the international research community discussing the harmonisation of standards and certification schemes worldwide,” explains Jan Erik Nielsen, Manager of the GSC Network and initiator of the new task. Other groups which could benefit from the new two-year task are stakeholders and public authorities in countries which do not have standards in place yet or which employ old ones. The network plans to develop guidelines for them on how to correctly use the international standards and to offer training materials and assistance.

Position Paper: Actions Needed to Pave Way for Net Zero Energy Buildings

Submitted by Baerbel Epp on August 3, 2015

Over 40 % of primary energy use and 24 % of greenhouse gas emissions are attributed to global energy use in buildings so architects and builders are being posed the challenge of creating highly energy-efficient structures. One vision promoted by stakeholders in many countries worldwide is Net Zero Energy Buildings (NetZEBs). To provide an analysis of the market potential and the actions required for a market uptake of this architectural design approach, the IEA Solar Heating and Cooling Programme published a position paper entitled SHC Net Zero Energy Solar Buildings in June. The 10-page summary is based on the insights of 82 experts from 19 countries, who have been conducting research within a joint IEA SHC Task 40 and Annex 52 of the Energy in Buildings and Communities Programme (EBCP) over several years (see the attached document). The photos show three French NetZEBs: a university research building on the tropical Island of La Reunion, an office building in Paris and a school in the city of Poitou‐Charentes.

Solar Heat WorldwideIt is the most comprehensive publication on the global solar water heating market: the annual study Solar Heat Worldwide. On behalf of the IEA Solar Heating and Cooling Programme (SHC), Austrian research institute AEE INTEC has gathered data on 2013 market development from 56 countries worldwide – covering 95 % of the world market. The institute has asked national stakeholders for newly installed capacity, type of technology and application. Accumulating such detailed information at global level gives a comprehensive overview of the world market for solar heating and cooling. According to an extrapolation of the missing 5 %, installers set up a total capacity of 55 GWth – or 78.6 million m2 of glazed and unglazed solar collectors – in these 56 countries. The pie charts show the growing importance of large domestic hot water applications in multi-family buildings as well as the tourism and public sector (see page 36/37 of the attached study). In 2013, 17 % of the newly installed collector capacity was installed in this segment (right), whereas it only accounts for 9 % of the total installed collector capacity in operation (left). The number of unglazed solar collectors for private swimming pools has diminished worldwide. Although they still make up 6 % of the total capacity, they only contributed 3 % to the new collector capacity in 2013. With 577 MWth (0.8 million m2) of newly installed capacity in 2013, non-residential applications, such as district heating, process heat and cooling, are still a real niche market.

IEA SHC Task 52: Seeking Cost-optimised Urban Energy Systems

Submitted by Baerbel Epp on May 30, 2015
How can solar energy be ideally integrated into an urban energy system? This has been the key question of IEA SHC Task 52: Solar Heat and Energy Economics in Urban Environments. One and a half years after the task´s start in January 2014, scientists from Germany, Denmark, Austria and Switzerland met in Freiburg for the third task meeting in mid-April to discuss cost assessments of existing plants and models for analysing complex urban energy systems. One of the first published outcomes is a study carried out by Austrian research institute AEE INTEC. It lists the costs of existing solar district heating plants in Denmark, Germany and Austria. The chart shows the preliminary results from levelised heat costs calculated for 29 collector fields of sizes between 500 and 55,000 m² integrated into district or micro grids.
