Thermal storage systems are needed to overcome solar intermittency and
make this energy source more flexible and competitive for concentrated
solar power plants. Single-tank sensible heat storage using both fluids
and materials is a promising option for reducing storage costs and
promoting the development of concentrated solar power. This work is a
thorough review on the parameters influencing the performance of a
dual-medium thermocline storage system for concentrated solar power
plants. Thus, indicators such as efficiency, utilisation rate, thermocline
thickness and energy efficiency of the storage system are presented in
order to quantify the performance of the system. In addition, the
impact of geometric and operating parameters on the performance of
the thermocline storage system has been discussed.
