IEA SHC Solar Academy: Current developments in thermal energy storage materials (1)
About this webinar:
In this webinar, get to know more about the latest R&D activities into compact thermal energy storage materials. The webinar will address the development of testing methods to characterize the materials and the exploration of reliable techniques to measure the state-of-charge in compact thermal energy storage. Moreover, it will provide insights into the comprehensive evaluation of stability of the materials, when used for years in practical applications.
Presentations will provide insight into the importance of round-robin tests to establish measurement protocols among the available experimental techniques. For the correct design and optimization of thermal energy storage systems using Phase Change Materials (PCMs), it is essential to determine PCMs' thermophysical in their working temperature range. Accurate thermal conductivity/thermal diffusivity data is needed to predict heat transfer.
The webinar will elaborate upon the integration into (digitalized) energy systems, where compact “Thermal Batteries” with reliable State of Charge (SoC) determination are aimed. For this purpose, promising methods for storage utilizing either Phase Change- or Thermochemical Materials are collected and classified – with studies ranging from material tests to large storage prototypes. Furthermore, Stability mapping of PCM and TCM, aims to review CTES material degradation mechanisms and develop recommendations for stability testing.
Q/A Session: This 90-minute webinar will include a 30-minute Q/A session and a recording of the webinar will be available online afterwards.
The webinar is organised by the Solar Academy of the IEA Solar Heating and Cooling Programme and hosted by ISES, the International Solar Energy Society.
Special announcement - Webinar re-run on 23 November 2023
ISES and the IEA SHC Solar Academy are happy to announce that this webinar will be broadcast again on 23 November 2023 at 6 AM GMT/UTC to accommodate our global audience, especially from Australia and Asia. The broadcast webinar will then be followed by a separate live Q/A with the webinar speakers starting at 7.15 AM GMT/UTC.
