While photovoltaic power generation has the advantage of emitting no CO2 during operation, it also has the problem that the amount of power generated is greatly affected by the weather, which sometimes leads to disconnection from the power grid. As a solution to this problem, latent heat storage(LHS) materials, which make thermal power plants easier to have flexible output adjustment capability, have gained much attention. Specifically, eutectic alloys are considered promising because of their homogeneous melting behavior. However, little choice is known about eutectic alloys used between 450-500 ℃, although heat storage systems require several LHS materials with different eutectic temperatures. To solve this problem, this research aims to find a new multi-component eutectic alloy by using SEM-EDS and TG-DTA analysis. Results showed the eutectic composition and temperature of Al-Cu-Mg-Si-Zn, and that it is one of the promising choices for LHS materials.
