This research project aims to increase the application range of Thermally Activated Building Systems (TABS). Usually TABS are used for heating and cooling purpose of buildings. The application range of the usage as energy storage element is limited by the surface temperature of the element to avoid overheating. Via a thermal decoupling of the thermal activated part with insulation from the building structure, it is possible to use TABS as an thermal energy storage. The results show a significant opportunity to time-shift the purchase of energy. The results show that it is possible to use TABS as a thermal energy storage element. It’s shown that the purchase of electrician energy for heating purpose can be shifted to economical or ecological optimal time points, for example if renewable energy is abundant in the electrical grid. The heating demand, covered by thermally charged TABS elements can be supplied by a fraction of 95%. Common TABS with a limited surface temperature can reach a coverage rate of 64 %. Nevertheless, the mean air temperature increases for this task by 1.1 K and the heat demand by 15.0 %.

Abstract This paper presents a lab-scale investigation of the use of structural concrete for sensible heat storage in power plants. Transient thermal and mechanical analyses are simulated via coupled finite element models to study the thermo-mechanical performance of a cylindrical concrete block with 4-in diameter and 8-in length under thermal loading. The model is validated by performing experiments on high strength concrete (HSC) cylinders with this geometry in an oven, which heats the specimens from the outside. The models are then modified to simulate thermal energy storage (TES) application with thermal loading applied at the interior surface of a hole running through the longitudinal center of the cylinder. Thermal cycles have a varying heating rate (5, 10, or 24 hours) followed by consistent durations of soaking (2 hours) and cooling (13 hours). In the TES simulations, a steel jacket is also applied to the external surface of the concrete cylinder to provide confinement. The resulting thermal distribution and maximum principal stresses during heating and cooling are observed as a function of time. This study provides insight into the mechanical requirements and impact on material integrity for concrete modules subjected to representative TES heating regimes.

A higher number of research institutions work on solutions for energy storage systems. Therefore a large number of differing approaches in competition among each other to develop storage technologies. At the TU-Wien, Institute for Energy Systems and Thermodynamics a novel thermal energy storage concept based on an active fluidized bed technology — the so called sandTES-heat exchanger technology — has been developed. The present paper describes the basic idea behind the key technology and the design methodology of a test rig in semi-industrial scale. In addition the results of selected preliminary experimental and numerical investigations are presented and discussed.
