Zinc Bromine Batteries Zinc Bromine batteries have gained commercial traction utilizing the zinc-based aqueous electrolyte to provide safe, durable, and flexible energy storage for 312 hour intraday applications Non Flow Chemistry
Flow Chemistry
Use Cases
Simple architectures have gained the most traction due to their manufacturability led by Eos Energy Enterprises and Offgrid Energy Labs Both companies boast mid 80-low 90% round trip efficiency particularly at higher discharge times.
Combining electrolyte tanks with plating of zinc on the anode side of the battery, the flow battery design offers flexibility and scalability in the storage of electricity.
Behind the meter C&I (e.g. data centres) Microgrids, weak-grid and off-grid markets Renewable firming and energy shifting
Work on these batteries started with Exxon in the 1970s with companies like Primus Power and Redflow furthering the design though both companies are no longer active
