Redflow is a global leader in energy storage
with a wealth of knowledge
that we look forward to sharing with you.

Who is Redflow?

Redflow Limited (Redflow) is a publicly-listed Australian company (ASX:RFX) that has developed the world’s smallest zinc-bromine flow battery, a powerful new energy storage system that can be used anywhere from individual homes right up to grid-scale deployment.

We designed and developed and continue to R&D two battery ranges: ZBM2 flow batteries for telecommunications, commercial, industrial and grid-scale applications and ZCell for residential energy storage.

Redflow batteries offer unique advantages over legacy battery types

Redflow batteries deliver unique benefits over traditional battery chemistries such as lead-acid and lithium-based batteries – by providing 100 per cent daily depth of discharge and retaining their full energy storage capacity throughout their warranted life. Redflow batteries are constructed from easily recyclable or reusable components.



10kWh zinc-bromine flow battery

Warranted total energy throughput of 36.5MWh, or 10 years whichever comes first

Expected energy throughput of 40MWh
Ideal for telecommunications and commercial applications at 48Vdc


 Large-scale utility and commercial applications

High energy density up to 600kWh in one LSB
Larger projects can interface multiple LSBs

Redflow ZCell home battery #4 W2ZCell

Home energy storage

The Australian-designed ZCell is a storage system
built around a unique zinc-bromine flow battery.

ZCell can deliver 10 kilowatt hours (kWh) of
stored energy each day, harvesting energy from
solar panels or lower-cost off-peak power,
for use when you need it.
