Large-scale energy storage is so-named to distinguish it from small-scale energy storage (e.g., batteries, capacitors, and small energy tanks). The advantages of large-scale energy storage are its capacity to accommodate many energy carriers, its high security over decades of service time, and its acceptable construction and economic …
Moreover, at a thermal storage temperature of 353.1 K, T-CO 2 energy storage cycle achieves a round-trip efficiency of 61.37% and an energy storage density of 0.989 kWh/m 3. The results indicate that the combined system exhibits excellent performance, particularly under relatively lower thermal source temperature.

This is defined in Eq. (1), where the total energy transferred into ( Ein) or out of ( Eout) the system must equal to the change in total energy of the system (Δ Esystem) during a process. This indicates that energy cannot be created nor destroyed, it can only change forms. (1) E in − E out = Δ E system.
