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. 

TASK 45 / 55: Guidelines on How to Design Seasonal Storage

Submitted by Baerbel Epp on August 1, 2016
Bore Hole StorageSeasonal storage is a key component in the transformation of today’s energy industry. Besides storing energy in summer for heating in winter, it can also be used to save waste heat from the industry and to increase the electricity production from biomass CHP plants. Experiences gathered with the technology during case studies were summarised as part of the study Seasonal thermal energy storage – Report on state of the art and necessary further R+D, which was published by Task 45, Large Scale Solar Heating and Cooling Systems, of the IEA SHC programme. Together with the Guidelines for Materials & Construction on the two most common storage types, borehole (see the chart) and water pit, it provides a good overview of the current advancements in this field (all three documents attached). Additional research into the design of seasonal storage will be carried out in follow-up Task 55, Towards the Integration of Large SHC Systems into District Heating and Cooling (DHC) Network. Interested stakeholders have been invited to join the kick-off meeting of Task 55 in Graz, Austria, between 19 and 21 October (see contact details below).

BobovnickySlovakia is the first country from Eastern Europe to join the IEA Solar Heating and Cooling Programme (IEA SHC). Since its admission, the small nation of only 5.5 million people has been represented by Artur Bobovnický (photo) from the Slovak Innovation and Energy Agency (SIEA). Bobovnický, who had previously held the job of Commercial Director at Slovakian SEVT, an office supplies business, took on the position of Director of Innovation and International Cooperation at SIEA in June 2014. Shortly thereafter, he was made aware of the great potential of the IEA‘s Technology Collaboration Programmes (TCPs) and successfully convinced the Slovakian government to sponsor membership.

China: Challenges and Opportunities of World’s Largest Solar Thermal Market

Submitted by Baerbel Epp on June 27, 2016
Reduced real estate investment has been the key reason for the strong decline of China’s solar thermal market. In 2015, the collector area installed annually was down to 43.5 million m² (30.5 GWth), which almost put the figure back to the level of 2009, and the growth rates in 2013/2014 and 2014/2015 were -18 % and -17 % respectively. The chart on annual output was taken from a presentation by He Tao, Professor at the China Academy of Building Research. He held it during the Executive Committee Meeting of the IEA Solar Heating and Cooling Programme in Spain at the beginning of June. When presenting the numbers, the professor also emphasised that the industry “has made great efforts to find new applications for space heating, solar process heat and space cooling” (see the attached presentation).

German Energy Transformation Scenarios: Solar thermal As Optional, Not Mandatory Technology for Least Cost Solutions

Submitted by Baerbel Epp on June 25, 2016
Sebastian HerkelHow much will the transformation of the German energy industry cost if it is to reach greenhouse gas emissions reductions of at least 80 % by 2050? The German Institute Fraunhofer ISE used its Renewable Energy Model REMod-D for Germany 2050 to perform the simulations necessary to answer this key question. REMod-D considers all kinds of energy end-use applications (in manufacturing, transport and residential segments) and each and every energy technology. Simulations are performed on an hourly basis to ensure the security of supply in all industries throughout the year. The studied scenarios differ with regard to drive concepts used in the private and commercial transport industry, the extent of energy retrofits in the building industry and the exact time at which coal will no longer be used to generate electricity. The most recent REMod-D study, which was published in November 2015, was called “What Will the Energy Transformation Cost? Pathways for Transforming the German Energy System by 2050” (see attached document in German). spoke with Sebastian Herkel from Fraunhofer ISE about the study’s solar thermal outcomes and the use of REMod-D in urban planning scenarios of Task 52 of the IEA Solar Heating and Cooling Programme.

Australia: Good Funding for Solar Process Heat, but Little Trust by Industry

Submitted by Baerbel Epp on June 22, 2016
IRR rates for solar thermal in AustraliaAustralia’s energy policy has been in the international press mostly for its shift back toward coal under the former Prime Minister Tony Abbott. However, Jeremy Osborne, Director of Energy Analysis & Engineering, said in an interview with that Australia did have a “supportive government despite all the news”.  Since July 2015, renewables for industrial processes has been one of the Australian Renewable Energy Agency’s (ARENA) investment priorities, which includes solar process heat. ARENA also published the report Renewable Energy Options for Australian Industrial Gas Users in September 2015, emphasising that lower-temperature process heat systems at around 100 °C are most “prospective at present” (see the attached document). Positive Internal Rates of Return (IRR) are achieved with gas prices above Australian Dollar (AUD) 5 per gigajoules (GJ). According to the report, the wholesale price for gas was between 6 and 8 AUD/GJ in 2014 and is expected to rise to between 9 and 12 AUD/GJ before the end of the decade.

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.
