The improvement of thermal energy storage systems implemented in solar technologies
increases not only their performance but also their dispatchability and competitiveness in the energy
market. Latent heat thermal energy storage systems are one of those storing methods. Therefore,
the need of finding the best materials for each application becomes an appealing research subject.
The main goal of this paper is to find suitable and economically viable materials able to work as
phase change material (PCM) within the temperature range of 210–270
◦
C and endure daily loading
and unloading processes in a system with Fresnel collector and an organic Rankine cycle (ORC).
Twenty-six materials have been tested and characterized in terms of their thermophysical conditions,
thermal and cycling stability, and health hazard. Two materials out of the 26 candidates achieved the
last stage of the selection process. However, one of the two finalists would require an inert working
atmosphere, which would highly increase the cost for the real scale application. This leads to a unique
suitable material, solar salt (40 wt % KNO
3
/60 wt % NaNO

). [-]
