AI Customer ServiceEconomic prospects for Li-ion and several flow batteries were compared in applications with discharge times longer than four hours via levelized cost of ES. Flow batteries with inexpensive reactants compare favorably to Li ion when discharge times exceed eight hours. LCOS adds the cost of charging to capital cost.
Existing commercial flow batteries (all-V, Zn-Br and Zn-Fe (CN) 6 batteries; USD$ > 170 (kW h) −1)) are still far beyond the DoE target (USD$ 100 (kW h) −1), requiring alternative systems and further improvements for effective market penetration.
Physical separation also imparts safety, at the cost of low energy density. The energy density of a typical aqueous flow battery (~20 Wh/L) is an order of magnitude lower than lithium ion. The relatively large size of flow batteries should be acceptable in many VRE + ES applications.
Flow batteries with inexpensive reactants compare favorably to Li ion when discharge times exceed eight hours. LCOS adds the cost of charging to capital cost. This advantages Li ion relative to flow batteries at shorter discharge times because it is more efficient.
A cost model is developed for all vanadium and iron–vanadium redox flow batteries. Electrochemical performance modeling is done to estimate stack performance at various power densities as a function of state of charge and operating conditions.
The power and energy capacity of flow batteries can be adjusted by adjusting the storage of liquid electrolyte, which also helps in adjusting the overall efficiency of the system. Both the power density and energy capacity are also independent in flow battery systems.
