In current research at Hochschule Mannheim, a latent heat storage system is being developed
based on a salt-ceramic composite material. The objective of this project is to contribute to the
development of energy storage systems capable of addressing the challenges posed by
intermittent renewable energy sources. The developed material aims to achieve a storage density
exceeding 200 kWh/m³. The research focuses on the analysis of eutectic salts, with a current
emphasis on a salt mixture of sodium chloride and calcium chloride. The phase change material
(PCM) is intended to acquire a porous ceramic matrix through an innovative sintering process,
embedding the salt to prevent leakage. The system is designed for operation at temperatures
between 500 and 800 °C. To analyze the thermal properties of the material, Differential Scanning
Calorimetry (DSC) is employed. Salts are tested in various proportions to achieve the optimum
latent heat. Furthermore, corrosion experiments contribute to the identification of suitable
ceramic materials. The research goal is to enhance the stability of the salt-ceramic composite
material through the integration of temperature-stable additives and the use of a porous ceramic
matrix
