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.

Austria: Prefabricated Roofboxes Create New Living Space on Multi-Storey Building Roofs

Submitted by Baerbel Epp on September 19, 2016
Haas Fertigbau ModulhausRenovating multi-storey buildings can be used to create new living space with an additional top floor. That’s where an Austrian consortium led by AEE INTEC comes in: It has developed the Roofbox, an entirely prefabricated modular living space. A Roofbox consists of a bathroom, a kitchen, a separate toilet or living room and bedrooms, and it can be ordered with an active solar water heater system already installed on its roof. Every Roofbox can be transported by an articulated lorry and is rigid enough to be lifted by crane for roof mounting. On 16 September, Austrian Haas Fertigbau showcased in its Großwilfersdorf factory a flat made up of two Roofbox prototypes – which, however, is still missing the solar thermal unit on top (see photo).

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. 
 

Global Job Statistics: Improved Methodology Results in 730,000 Jobs Worldwide

Submitted by Baerbel Epp on July 5, 2016
Job Chart IRENATypically, the number of jobs in the global solar heating and cooling industry is based on general assumptions and fragmentary extrapolations. The authors who publish the two annual studies on these job numbers have tried each year to improve upon the database – with success, although they still end up with different figures. The Solar Heat Worldwide Edition 2016 published by Austrian institute AEE INTEC estimated that 730,000 people had a job related to the manufacturing, installation or maintenance of solar thermal systems in 2014. The study Renewable Energy and Jobs - Annual Review 2016 by the International Renewable Energy Agency (IRENA) put the figure at 939,000 in the global solar heating and cooling industry in 2015 – 12 % of the world’s 8.1 million jobs in the renewable sector (find both studies attached).

ESCO Project Funding: Search for Attractive Case Studies to Fill Project Pipeline

Submitted by Baerbel Epp on July 5, 2016
Energy Contracting FundSolar heating and cooling has not been bankable yet despite various systems confirming expected performance and O&M costs. Project budgets are usually too small and the technology suppliers do not pass the stringent requirements of creditworthiness, which leaves the financial provider with a high-risk scenario. Accordingly, Energy Service Companies (ESCOs) have faced severe financing issues, which slow down the expansion of their business. It is good news to them that two recently launched projects also focus on facilitating the creation of an investment fund for solar thermal ESCO projects: First, there is the Feasibility Study - Energy Contracting Fund, which is jointly coordinated by the German Investment and Development Corporation Bank (DEG) and German SHC turnkey provider Industrial Solar; the second project, TrustEE – enhancing investment conditions for industrial energy efficiency and renewable energy projects, is from the EU and has been coordinated by Austrian institute AEE INTEC.
 

Austria: Decision on Operating Company for Big Solar Graz Expected Soon

Submitted by Baerbel Epp on June 17, 2016
Gleisdorf Solar 2016“Large-scale solar thermal systems in the GW range – an insignificant niche market or the future for solar thermal?” was the official title of a panel discussion at the Gleisdorf Solar conference in Austria in early May. The most important question was: What will be next for the planned 350 MWth solar district heating system called Big Solar in the Austrian city of Graz? “The challenge was to adapt the Danish district heating solutions to Austrian conditions,” emphasised the project’s initiator, Christian Holter (right), Managing Director of S.O.L.I.D. Meanwhile, Christian Stadler (left), Managing Director of one of Arcon-Sunmark’s subsidiaries, Arcon-Sunmark Germany & Austria, represented the company that has stated his own interest in realising Big Solar.

Austria: Green Brewery Göss Receives IEA SHC Award

Submitted by Baerbel Epp on June 15, 2016
Gleisdorf Solar 2016At the international conference Gleisdorf Solar in Austria, Austrian brewery Göss was presented with the SHC Solar Award, the "Oscar" of the solar heating and cooling industry. The IEA Solar Heating and Cooling Programme (IEA SHC) created this award to recognise outstanding achievements by suppliers or users of solar thermal technology. The photo shows master brewer Andreas Werner (right), who received the prize from the hands of Doug McClenahan, Chair of the SHC Solar Award committee (second from right), and Ken Guthrie, Chair of IEA SHC (second from left).

IEA SHC Study Solar Heat Worldwide: Global View on Country Statistics

Submitted by Baerbel Epp on June 6, 2016
SHWW regional market developmentThe recently launched report Solar Heat Worldwide 2016 offers a comprehensive overview of the global and national market development in the solar heating and cooling sector (see the attached document). On behalf of the IEA Solar Heating and Cooling Programme (SHC), Austrian research institute AEE INTEC gathered data on 2014 market changes from 61 countries worldwide, one more than last year (Lesotho). The authors of the report, Franz Mauthner, Werner Weiss und Monika Spörk-Dür, asked national stakeholders about the newly installed capacity in 2014, the type of technology used, the share of applications and, for the first time, the costs of solar thermal systems in their countries. The chart shows the market growth in newly installed capacity in 2013/2014 (glazed as well as unglazed collectors) worldwide and broken down by economic region. The report is the most comprehensive publication on the global solar heating and cooling industry and has been referenced by many international studies from IEA, REN21 and IRENA.

IEA SHC: Levelised Cost of Heat and the Calculations behind It

Submitted by Baerbel Epp on May 28, 2016
The main objective of IEA SHC Task 52, Solar Thermal in Energy Supply Systems in Urban Environments, is to call attention to both the technical and economic aspects of solar heating and cooling usage in densely populated urban areas. Urban planners and commercial clients want to know the costs compared to the energy output generated by various solar heating technologies. A method to benchmark different solar heat production systems is Levelised Cost of Energy (LCOE). This method is described by the IEA as the “average price that would have to be paid by consumers to repay exactly the investor/operator for the capital, operation and maintenance and fuel expenses, with a rate of return equal to the discount rate”. The chart shows the LCOE for different applications and system sizes in northern / central European climates, taken from the most current Task 52 study Technology and Demonstrators (for further details see table below). The author of the study, Franz Mauthner from Austrian research institute AEE INTEC, contributed to this article, which elaborates on the method and the calculations behind it.
