Thermische Energiespeicherung für nachhaltige Energietechnologien

01.08.2014 - 30.09.2020

In this FFG “Leitprojekt” project we are part of a  consortium of 18 partners and 5 development lines. The overall goal is to develop advanced thermal storage materials, thermal storage devices, numerical simulation tools and control systems to integrate these into energy systems in industry, for mobility applications and in buildings, in order to strengthen these sectors and bring the Austrian industry in a leading European position in advanced thermal energy storage. For thermal storage materials, the goal is to arrive at novel sorption and composite materials for low temperature applications and to investigate novel phase change and thermochemical materials for medium temperature storage for industry. Novel thermal storage devices with significantly improved energy density will be developed for sorption seasonal storage of solar energy in buildings, for medium temperature phase change thermal storage and for the compact storage of surplus heat at medium temperatures in industry, while new concepts for storage of heat in conventional cars, railway vehicles and in hybrid and electric vehicles will be developed. Storage materials, components, systems and control strategies are integrally developed in dedicated work packages, thus optimizing the cross-fertilisation of the developments for the three different application areas: buildings, industry and mobility. In our project part we cooperate with the Austrian Institute of Technology (AIT), the Austrian company SOLID and the German company Südzucker AG. Our aim is to use derivatives of sugar alcohols to store energy via a phase transfer from the solid to the liquid phase and release it afterwards be inducing crystallization. The project start was 10/2014.
