Solar thermal energy storage has the potential to help transition our infrastructure away from fossil fuels towards alternative energy. Solar thermal energy is generally stored as latent or sensible heat, but using the sun?s energy to drive a phase change chemical reaction can provide energy densities comparable to fossil fuels (~15 Mega Joules per liter). Here, I will present a 3-Omega, frequency domain thermal measurement, to quantitatively characterize the behavior of phase change materials at temperatures up to 800 degrees Celsius. Using this capability, the search for the optimal material system is on. An advanced grid level energy storage system is needed to provide energy to people when the sun is not shining or when the wind stops blowing; solar thermal energy storage can fill this void.
