Flow batteries have a higher initial cost compared to other battery types due to their complex design, which includes separate tanks for storing electrolytes, pumps, plumbing, and control systems. Moreover, their relatively low charge and discharge rates necessitate the use of substantial quantities of materials.
Flow batteries typically include three major components: the cell stack (CS), electrolyte storage (ES) and auxiliary parts. A flow battery's cell stack (CS) consists of electrodes and a membrane. It is where electrochemical reactions occur between two electrolytes, converting chemical energy into electrical energy.
The capital cost of flow battery includes the cost components of cell stacks (electrodes, membranes, gaskets and bolts), electrolytes (active materials, salts, solvents, bromine sequestration agents), balance of plant (BOP) (tanks, pumps, heat exchangers, condensers and rebalance cells) and power conversion system (PCS).
At their heart, flow batteries are electrochemical systems that store power in liquid solutions contained within external tanks. This design differs significantly from solid-state batteries, such as lithium-ion variants, where energy is enclosed within the battery unit itself.
Various flow battery systems have been investigated based on different chemistries. Based on the electro-active materials used in the system, the more successful pair of electrodes are liquid/gas-metal and liquid-liquid electrode systems.
However, the key to unlocking the potential of flow batteries lies in understanding their unique cost structure and capitalizing on their distinctive strengths. It’s clear that the cost per kWh of flow batteries may seem high at first glance. Yet, their long lifespan and scalability make them a cost-effective choice in the long run.
