The zinc–bromine (ZBRFB) is a hybrid flow battery. A solution of is stored in two tanks. When the battery is charged or discharged, the solutions (electrolytes) are pumped through a reactor stack from one tank to the other. One tank is used to store the electrolyte for positive electrode reactions, and the other stores the negative. range between 60 and 85 W·h/kg. Zinc-bromine flow battery companies like Redflow, Primus Power, and Gelion Technologies dominate the energy storage market with scalable solutions for renewable integration. [pdf]

Technical merits make redox flow batteries well-suited for large-scale energy storage. Flow batteries are normally considered for relatively large (1 kWh – 10 MWh) stationary applications with multi-hour charge-discharge cycles. Flow batteries are not cost-efficient for shorter charge/discharge times. Market niches include: • : short and/or long-term energy storage for use by the grid [pdf]
