What is a flow battery?
Flow batteries allow for independent scaleup of power and capacity specifications since the chemical species are stored outside the cell. The power each cell generates depends on the current density and voltage. Flow batteries have typically been operated at about 50 mA/cm 2, approximately the same as batteries without convection.
What is the difference between power and capacity of a flow battery?
The capacity is a function of the amount of electrolyte and concentration of the active ions, whereas the power is primarily a function of electrode area within the cell. Similar to lithium-ion cells, flow battery cells can be stacked in series to meet voltage requirements. However, the electrolyte tanks remain external to the system.
How do flow batteries increase power and capacity?
Since capacity is independent of the power-generating component, as in an internal combustion engine and gas tank, it can be increased by simple enlargement of the electrolyte storage tanks. Flow batteries allow for independent scaleup of power and capacity specifications since the chemical species are stored outside the cell.
What determines the energy storage capacity of a flow battery?
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
How much energy can a flow battery provide?
For instance, 1 GWh can fulfil the energy demand of approximately 130,000 homes in Europe for a full day of operation.6 A flow battery target of 200 GWh by 2030 is therefore equivalent to providing energy to 26 million homes – enough to provide energy to every household in Italy, or to all homes in Belgium and Spain combined.7
How can capacity markets incentivise the deployment of flow batteries?
With regards to revenue mechanisms, capacity markets in particular could incentivise the deployment of flow batteries by offering financial incentives for the long-term, continuous availability of the energy storage capacity they provide, allowing them to compete with traditional forms of generation such as gas or coal-fired power plants.
