How a VRFB works
A VRFB circulates vanadium electrolyte through electrochemical cells. Energy capacity is largely determined by electrolyte volume and tank size, while the cell stack determines power.

Duration and duty
Duration, cycling pattern, efficiency, temperature, site requirements and service terms all matter when choosing a system.
Project economics
Compare complete installed cost, operating cost and the value of delivered energy. Test outright electrolyte purchase against a negotiated lease.
Technology / Context
What is a vanadium flow battery?
A vanadium redox flow battery stores energy in liquid electrolyte held in external tanks. Pumps circulate the electrolyte through a cell stack during charging and discharge. The design lets engineers select power and energy capacity with greater independence than in many packaged batteries.
What should a buyer compare?
Compare delivered energy, round trip efficiency, operating profile, footprint, climate controls, maintenance, warranties, safety engineering and total lifetime cost. Suitability depends on the specific application.
