Addressing energy storage needs at lower cost via on-site thermal energy storage in buildings
Adewale Odukomaiya,Jason Woods,Nelson James,Sumanjeet Kaur,Kyle R. Gluesenkamp,Navin Kumar,Sven Mumme,Roderick K Jackson,Ravi Prasher,Ravi Prasher +9 more
TL;DR: In this article, the authors proposed a framework to calculate the levelized cost of storage (LCOS) for on-site thermal energy storage (TES) in buildings to enable a direct comparison with electrical storage technologies such as Li-ion batteries.
Exploring additives for improving the reliability of zinc nitrate hexahydrate as a phase change material (PCM)
TL;DR: In this article, the authors investigated heterogeneous nucleation in a chosen thermal energy storage material, Zinc nitrate hexahydrate, Zn(NO3)2, and showed that the heterogenous nucleators reduced 3.0°C supercooling, increased the energy storage, and survived up to 750 cycles of repeated melting and solidification.
