Nassau flow battery price

What is the capital cost of flow battery?

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).

How do you calculate the cost of a flow battery?

Electrode materials includes bipolar plates, end-plates and graphite felts. The total costs of flow battery (C RFB) are expressed in terms of $ (kW h) −1 through dividing the costs of all these components (Cstack, Celectrolytes, CBOP and CPCS) by the required energies of the applications (Etotal = P × tdischarge, where P = Vdischarge × tdischarge).

Are aqueous flow batteries still competitive?

It can be seen that competitive systems are still realistic from the current status of aqueous flow batteries, while their non-aqueous counterparts remain challenging unless tremendous improvements (e.g. higher current density, wider voltage window) have been made on several aspects.

Why are flow batteries rated based on stack size?

Since other batteries have a fixed energy to power (E / P) ratio, the architecture of flow batteries enables energy and power to be decoupled, which can be adjusted with the amount of the electrolytes and the sizes of the total electrode areas, hence the power rating is based on the stack size or number.
