A new heat storage material could help to significantly improve the energy efficiency of buildings. Developed by researchers at Martin Luther University Halle-Wittenberg (MLU) and the University of Leipzig, it can be used to store surplus heat and release it back into the environment when needed. Unlike existing materials, the new one can absorb significantly more heat, is more stable, and is made of harmless substances. In the Journal of Energy Storage the team describes the formation mechanism of the material.

The invention is a so-called shape-stabilized phase change material. It can absorb large amounts of heat by changing its physical state from solid to liquid...
