The need for reduction of fossil fuel exploitation along with their emissions as well as the urgency of coping with the latest challenges arose in the energy sector in the last decades to sustain and to make the well-known renewables more resilient, have pushed towards the development of new TES solutions. The manufacturing of Form-Stable Phase Change Materials (FPCM) offer a sustainable, clean, flexible and compact option for collecting thermal energy thanks to their ability of storing higher energy density contents compared to the traditional sensible energy storage-based solutions and proving to be a more effective option for a wider range of temperature applications.
