Abstract
More than half of the energy used in total comes in the form of heat energy. An essential environmental protection technique to increase energy efficiency is learning how to employ thermal energy storage (TES) technology to fully use intermittent and unstable heat, such as solar heat utilization and industrial waste heat. Sensible heat storage, latent heat storage, and thermochemical heat storage are all types of thermal energy storage. This work describes the creation of ZrO2/SiC-H2O nanofluids and their characteristics for use in energy storage applications. Results reveal that increasing the concentration of ZrO2/SiC NPs from 0.3 gm/L to 1.2 gm/L at photon wavelength (=380nm) increased absorbance by roughly 83.7% and reduced transmittance by 81.2%. Additionally, when ZrO2/SiC NP concentrations rise, the absorbance rises as well, indicating improved nanofluid dispersion. Additionally, when the concentration of ZrO2/SiC NPs reached 1.2gm/L, the electrical conductivity of ZrO2/SiC-H2O nanofluids improved by nearly 74%, and the melting time reduced with an increase in the concentration of ZrO2/SiC nanoparticles.
