The energy storage density of the LAES is an order of magnitude lower at 120– 00 W h/L, but the energy carrier can be stored at ambient pressure. Pumped hydro storage has the lowest energy density of (0.5–1.5) W h/L while compressed air energy storage and flow batteries are at 5–30 W h/L. 5.2. Economic comparison
The energy cost includes the cost of the active material, salt, solvent, and storage tanks. In aqueous systems, due to the low cost of solvent and salt, energy cost is mainly determined by the active materials as well as the storage tanks. Therefore, the energy cost of flow batteries with different types of active materials varies greatly [18].
