E v = latent volumetric energy storage. E v * = volumetric energy storage within 20 C of T m (T m ± 10 C). This value accounts for the small but significant additional energy stored in the form of sensible heat. We have assumed a specific heat capacity (C p) value of 1.5 J mol −1 K −1 for the calculation because of the absence of data in the solid and liquid state.
In a solar power plant, the heat transfer fluid (HTF) flows through the solar receiver and transfers heat to the heat storage system or for the conversion into the electricity system. The heat transfer fluid differs from the working fluid. The latter is employed in a ...

By capturing all efficiencies in a systematic way, various TES technologies …
Particles under d p ≈ 1 mm can be easily fluidized without very high gas flow rates, which ensures a reasonable pumping cost.The fluidization process of solid particles strongly depends on the density and size of the particles. Geldart (1973) defined the fluidization regimes shown in Fig. 2, which are currently considered to be the standard …
Liquid air energy storage (LAES) uses air as both the storage medium and working fluid, and it falls into the broad category of thermo-mechanical energy storage technologies. The LAES technology offers several advantages including high energy density and scalability, cost-competitiveness and non-geographical constraints, and hence has …
