TASK 58: Material & Components for Thermal Energy Storage

This joint SHC Task 58 / ECES Annex 33 deals with advanced materials for latent and chemical thermal energy storage, Phase Change (PCM) and Thermo Chemical (TCM) materials.

IEA Solar Heating & Cooling Technology Collaboration Programme

The Solar Heating and Cooling Technology Collaboration Programme (SHC TCP) was established in 1977, one of the first programmes of the International Energy Agency, to promote the use of all aspects of solar thermal energy. The SHC TCP's work is unique in that it is accomplished through the international collaborative effort of experts from member countries and the European Union.

The benefits of this approach are:

  • accelerates the pace of technology development
  • promotes standardization
  • enhances national R&D programmes
  • permits national specialization
  • saves time and money

What's New
  • Lessons learned from first IEA SHC online meetings - “It worked very, very well and we saved a lot of emissions,” said one of the participants in the two-day online workshop organised by research platform Solar Neighborhood Planning, also known as Task 63. On 11 and 12 March, 42 people based in 10 different countries, ranging from Canada and Sweden to China and Uganda, discussed the work plan of this recently started four-year project supported by the IEA Solar Heating and Cooling programme.

  • Call for Proposals: SBE21 Heritage - The conference will be dedicated to the sustainable improvement of the built heritage, a research area that has grown significantly over the last 10 years and that is currently gaining even more momentum. With a focus on “Renovating historic buildings for a low-carbon built heritage”, the conference will foster a multidisciplinary dialogue between scholars and practitioners working in the fields of energy efficiency and historic building conservation with the aim of finding together the solutions that will bring our common heritage into a sustainable future.

  • Hybrid solutions maximise solar yield per area - A record 840 people registered for the PVT solutions for buildings and industry webinar in order to learn more about the wide range of applications in which hybrid PV-Thermal systems can be used. This two-in-one technology offers attractive payback periods whenever a constant amount of heat is needed all year round and electricity is consumed on site. (Posted: 2020-04-30)
  • Compact heat battery with virtually no heat loss - A compact thermochemical seasonal storage system put up at a demonstration site in Warsaw, Poland, is working as expected. The prototype, developed and tested as part of an EU research project called CREATE, consists of three evacuated modules filled with 400 litres of salt each to store heat with no heat loss by hydrating the material (see the photo on the left).

  • Solar Energy Buildings to make cities fit for the future - Buildings account for around 40 % of the world’s primary energy consumption. Hence, they are the number one cause of resource consumption on earth. (Posted: 2020-02-20)
