This project focused on a combined electrical-thermal energy storage system to increase the energy efficiency and improve the system integration of renewable energies in self-sustaining homes and apartment buildings. A phase-change energy storage system based on hydrates was developed. The phase-change energy storage was integrated into the supply system in such a way that it can be charged during the day via solar energy and at the same time is able to cool the house. In the evening, the stored energy can be used to further cool the house, thus saving electric energy and prolonging battery life. This enables improved system integration of renewable energies with fluctuating power output and increased living comfort. During the project, a test stand was created to validate the developed physical-mathematical models. This allowed research and development of a full-scale prototype.
