IEA SHC: Most Effective Solar Cooling Storage Technologies

Submitted by Baerbel Epp on September 27, 2017
Scientists from IEA SHC Task 53, New Generation Solar Cooling & Heating Systems, have compared the cost, efficiency and adaptability of solar cooling storage solutions and are now creating a report about the technologies most suitable for a given application. The researchers examined both thermal and electricity storage systems. But whereas the report can soon be used as guidance for choosing the most apt solution to heat and cool buildings, it will not provide a recommendation in favour of storing electricity or thermal energy.

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. 
 

Austria: Task 42 Meeting on Compact Thermal Energy Storage Systems

Submitted by Baerbel Epp on March 3, 2015
Task 42 MeetingIEA-SHC Task 42, entitled Compact Thermal Energy Storage, has entered into its final year and will end in December 2015. In February 2015, 44 scientists met for the 13th Experts Task Meeting in Vienna, Austria, to discuss the characterisation and development of materials for latent heat storage systems. This included phase change materials (PCM) like paraffin and thermo-chemical materials (TCM), such as sodium hydroxide solutions or zeolites. During the three-day meeting, the task members also visited the cogeneration plant Simmering in Vienna. The photo shows them in front of two pressurised water tanks with a total volume of 11,000 m3. The tanks are charged and discharged with 145 GWh annually and are operated to decouple heat energy production from demand in the district heating network of Vienna.

Storage Solution for Solar Thermal Energy (2004)

Submitted by Raquel Ponte Costa on May 31, 2011

This is a study concerning solar storage technologies and materials presented by J. C. Hadorn from the Swiss Federal Office of Energy. Many schemes and graphics provide a visual explanation of how all presented technologies work and how they can be connected to different energy supply technologies or with energy grid.Some schemes of potentially useful materials for this function thanks to their energy densities are also available.

Ventilation Performance of Solar Chimney with Built-in Latent Heat Storage (2006)

Submitted by Raquel Ponte Costa on March 12, 2010

This document was prepared by two researchers from the Osaka University, Department of Architectural Engineering. It describes the prototype solar chimney with PCM (Phase Change Material) storage, together with a numerical model for predicting air flow rate in a solar chimney and temperature of aluminum plate, air and PCM.

More Research Needed for New Storage Materials

Submitted by Baerbel Epp on November 17, 2008

If solar energy is to be the primary or only source of heat for houses in the future, there will arise a need for storing it more efficiently. Materials have to be found that are able to hold more energy than water, but with less volume and higher loss. Task 32 of the International Energy Agency's (IEA) Solar & Cooling programme was working on this issue. The scientists presented their results at the Eurosun 2008 in Lisbon, at the beginning of October.
