Feb 14, 2025 · Here''s why flow batteries stand out: Scalability: The energy capacity of flow batteries can be easily adjusted by varying the size of the electrolyte tanks, making them ideal
Flow battery have a wide range of energy storage capacity, ranging from a minimum of several tens of kilowatts to a maximum of nearly 100 megawatts. At present, China’s largest flow battery demonstration project has achieved 100 MW/400 MWh. At present, there are three technical routes for flow batteries to be better:
Scalability: One of the standout features of flow batteries is their inherent scalability. The energy storage capacity of a flow battery can be easily increased by adding larger tanks to store more electrolyte.
Flow batteries comprise two components: Electrochemical cell Conversion between chemical and electrical energy External electrolyte storage tanks Energy storage Source: EPRI K. Webb ESE 471 5 Flow Battery Electrochemical Cell Electrochemical cell Two half-cellsseparated by a proton-exchange membrane(PEM)
K. Webb ESE 471 3 Flow Batteries Flow batteries are electrochemical cells, in which the reacting substances are stored in electrolyte solutions external to the battery cell Electrolytes are pumped through the cells Electrolytes flow across the electrodes Reactions occur atthe electrodes Electrodes do not undergo a physical change Source: EPRI
Volume of electrolyte in external tanks determines energy storage capacity Flow batteries can be tailored for an particular application Very fast response times- < 1 msec Time to switch between full-power charge and full-power discharge Typically limited by controls and power electronics Potentially very long discharge times
In terms of energy density, since the flow battery is limited by the composition of the electrolyte, the energy density is relatively low. For a large-scale energy storage project with a 100 MW/400 MWh flow battery, using the same site, if it is replaced by a lithium battery, it can reach 800-1,000 MWh.
