Thermal Storage

The lecture by Stefan Gschwander will give an overview on different thermal storage technologies (sensible, latent and TCM/sorption). It will compare available storage densities and will give some examples on storage systems. For both the sorption heat storage and latent heat storage, a suitable storage material with high storage density, low environmental impact and low cost is essential. Phase change slurries (PCSs) consist of a phase change material (PCM) and a carrier fluid. Depending on its state of matter the PCM is either suspended or emulsified in the carrier fluid. This facilitates the conveying of the PCS in a hydraulic system independent of the state of matter of the PCM. PCSs may be used in industrial cooling processes as heat transfer fluids as they can store a high quantity of heat within a small temperature range and can transfer the stored heat homogenously keeping a relatively steady temperature level. The usage of a fluid that stores energy and is transportable at the same time helps reducing energy losses. By dispersing the fine PCM droplets in water a high surface to volume ration is created that enlarges the heat transfer rate.

Stefan Gschwander | Fraunhofer Institute for Solar Energy Systems ISE

Stefan Gschwander graduated from the Saarland University as Master in Technical Biology and Bionics in 2002. He has since built up 15 years of professional experience in the research areas of the thermal use of solar energy, solar building, energy storage and the rational use of energy. Predominantly active in research field of the characterization of Phase-Change Materials (PCMs) or latent heat storage systems, he evolved from an examined scientific assistant, over a research associate and project manager to the head of the research group »Phase-Change Materials« at the Fraunhofer-Institut für Solare Energiesysteme ISE.
Currently he is working at Fraunhofer ISE doing development of storage materials and storage systems with the focus on latent heat storage.
He is also leading the working group on »Test and Characterization« within the IEA SHC Task 42 / ECES Annex 29 on »Compact Thermal Energy Storage« from 2009 - 2015, was a committee member of the 10th ISES EuroSun Conference in 2015 and of the 11th IIR Conference on Phase Change Materials in 2016.
