Most solar thermal power plants are able to incorporate large capacity thermal energy storage (TES) units. TES
increases the capacity factor and allows for more dispatchable power [1]. It also offers ancillary services to the grid.
This makes concentrated solar power (CSP) a very attractive electricity generation technology compared to other
renewable electricity generation systems. Therefore TES provides a high potential for the penetration of CSP in the
existing grid [2].
A recent review on the state of the art of high temperature TES for power generation focusing on concepts,
materials and simulation assessed the added value of TES technology in CSP systems [3]. However very few case
