Despite how attractive solar power systems may seem, their low energy efficiency is the biggest
barrier to development. The energy efficiency is greatly increased when a thermal energy storage
is integrated into the entire energy extraction process. For solar thermal power, nanofluids of
birnary carbonate have shown to be a viable option for thermal energy storage at high temperature
and transmission medium. The increase in specific heat capacity(Cp) for the binary carbonate,
Na2CO3-K2CO3 (60:40 mass ratio), using CuO and ZnO nanoparticles was up to 32.4% at 540°C.
This research offers insights into how the use of two nanoparticles can significantly increase the
Cp value of the binary carbonate salt. Moreover, it focuses on determining whether utilizing these
nanoparticles has any negative consequences on the fusion's onset and offset temperatures. This
reasearch shows that the addition of nanoparticles has no adverse impact on the target
temperatures.
