Both types of energy storage are proven to be sustainable and they have a similar scale and cost (500–2000 € kW −1), When the distance increases, the investment cost (a pipeline network must be installed) and the energy consumption by the circulation pumps increase, decreasing the overall efficiency.
The necessity of this process is particularly evident in applications for the storage of renewable energies. There, the cyclical charging and discharging of liquid lead acid batteries creates an electrolyte stratification, which can only be compensated unreliably and with disadvantages during operation without a circulation system.
