Cover Feature: Perspectives and Limitations of Tartaric Acid Diamides as Phase Change Materials for Sustainable Heat Applications (ChemSusChem 13/2025)

Phase change materials pave the way to revolutionizing energy storage technologies as cost-effective, scalable solutions without rare earth dependency. In addition, if they are bio-derived, the carbon footprint of such thermal battery technology can be minimal. Tartaric acid-based phase change materials melt at temperatures between 130 and 190 °C with high thermal energy storage capacity, thus making them promising candidates for thermal batteries.
