Solid-state solar thermal fuels (SSTFs) serve as efficient means of storing solar energy as chemical potential energy in a closed loop system and releasing it as heat on-demand. An ideal SSTF requires photoswitchability in visible-region without any external heating as well as extended storage times.
(Na0.5Bi0.5)0.75Sr0.25TiO3–x Sm2O3 ceramics (denoted as NBSTSx) were obtained by the solid-state reaction method, and their crystal structure and morphological characteristics were characterized by X-ray diffractometer mapping (XRD) and scanning electron microscopy (SEM). The NBSTSx ceramics, when doped with a …

By comparing the reliability indexes in Table 4, Table 5, Table 6, among the three typical energy storage charging and discharging strategies designed in this paper, strategy I is to obtain the minimum fluctuation, and its inhibiting ability to the fluctuation of the scenic power output is the strongest among the three strategies, but the improving effect …
For solar thermal energy utilization in relatively low temperatures, a lab-scale direct contact, latent thermal energy storage unit using a form-stable high-density polyethylene (HDPE) was developed. The phase change material (PCM), the form-stable HDPE, does not fluidize nor adhere even after melting, and this particular property permits a direct contact heat …
