Two mixtures containing Ca(NO3)2•4H2O and KNO3 or Mg(NO3)2•6H2O of composition close to their eutectics are described as promising thermal heat storage (TES) materials suitable for passive solar heating applications. Supercooling is hindered by a system which apparently may be applied to other salt mixtures of this type. A comparison is made with other salt mixtures containing magnesium salts previously studied. Tests are in progress to confirm that no efficiency reduction after many heating/cooling cycles occurs.

Latent Heat Storage

The industrial sector is increasingly obliged to reduce its energy consumption and greenhouse gases emissions to contribute to the world organizations’ targets in energy transition. An energy efficiency solution lies in the development of thermal energy storage systems, which are notably lacking in the low-temperature range (50–85 °C), for applications such as district heating or low-temperature waste heat recovery. This work aims to bring a latent heat storage solution from material selection to prototype evaluation. The first part of this paper is dedicated to the characterization and aging of a phase change material selected from a screening of the literature (fatty acid mixture mainly composed by stearic and palmitic acid). Then, this material is encapsulated and tested in a prototype whose performances are evaluated under various operating conditions. Finally, a numerical model validated by the experimental results is used to explore the influence of a wider range of operating conditions, dimensioning choices, and material conductivity improvements.
