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.
Tanks with high storage capacity and reduced losses are key to an increased solar heat share in households. Austrian research institute AEE INTEC has recently inaugurated a pilot research facility which promises exactly that: greater storage capacity than water and almost zero energy losses even in seasonal mode. The heart of the test facility are two low-pressure vessels filled with 750 kg of zeolite beads or spheres each. “Our first measurements since the beginning of October were very promising,” confirms Wim van Helden, head of the research project at AEE INTEC. “We reached a storage density of 180 kWh/m³, which has never been achieved before in a device of this size.” The research is part of an EU-funded project called COMTES – Combined Development of Compact Thermal Energy Storage Technologies and was co-financed by the Austrian Climate and Energy Fund.
