A battery-based energy storage system in which energy is stored chemically in an electrolyte solution
Advantages
Lowest LCOS (10 years lifecycle) among electrochemical energy storage systems
Capacity and energy density can be increased independently from each other
Service interval 1 year
High cyclical resource – up to 20 000 cycles (20 years)
Conditions for the effective use of batteries of various types:
Flow batteries are most efficient for long periods of use. This is due to the long service life of the electrolyte and the ability to increase the capacity independent of power.
Lithium-ion batteries can be switched on and off faster than flow batteries. Therefore, their use may be more short-time.
Hybrid systems using both types of batteries achieve the best economic performance and ensure the planned operation of a facility with minimal energy costs.
