00925njm 22002777a 4500 dc Müller, Lukas author Rubio Pérez, Gabriel author Bach, Andreas author Muñoz Rujas, Natalia author Aguilar Romero, Fernando author Worlitschek, Jörg author 2020-10 Measuring thermo-physical properties of phase change materials (PCM) in a consistent and reliable manner is essential for system layout of thermal energy storages and correspondingly material selection. Only if basic properties are assessed in a comparable way a selection process leads to the top candidate for any given application and thus enhances market penetration of renewable energy sources coupled with thermal energy storage. In this study, we focus on differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) as basic assessment techniques and develop consistent measurement procedures to create a database with comparable results. We show consistency of the measured results through analysis of coefficient of variation (CV), being in the mean 1.69%, 0.05%, 0.06% and 4.00% for enthalpy, melting onset, melting peak and maximum operating temperature, respectively. Overall, 23 PCM have been measured with the presented methodology, which was mainly possible due to the reduced measurement and preparation time per PCM compared to standard techniques, while achieving similar accuracy and precision. https://hdl.handle.net/10259/11443 10.3390/ma13204486 1996-1944 Phase change materials Latent heat storage Thermal energy storage Differential scanning calorimetry Thermogravimetric analysis Energy Consistent DSC and TGA Methodology as Basis for the Measurement and Comparison of Thermo-Physical Properties of Phase Change Materials
