Why Redflow?

Redflow’s zinc-based flow batteries have many unique features and are ideally suited to time-shifting energy on a daily, full-cycle basis, as well as providing emergency power supplies in a wide range of climates.
Other key benefits include:


  • Modular design – scalable to multi-100's MWh systems

  • Core design allows for redundancy. Expand as needs increase

  • Hibernation mode allows for extended preservation of stored energy for indefinite periods

  • Suits medium to longer duration storage applications

Environmentally friendly

  • Battery is made from HDPE plastic which is commonly recycled into plastic bottles

  • Electronics – follows standard pathway for electronics recycling

  • Electrolyte – R&D program to verify potential to reuse/partial reuse

  • Minerals sourced from non-conflict areas

  • No CO2 emitted from operation


Operational flexibility

  • Up to 12 hours discharge and potential to extend with hibernation mode

  • Less than 1 second start up response time

  • Batteries can be left 100 per cent charged indefinitely

  • System can be ‘parked’ at any state of charge, with no impact on performance


  • No risk of thermal runaway - non-flammable materials, verified to UL9540A

  • Excellent tolerance for high ambient temperatures without external cooling

  • Bromine-based electrolyte is non-flammable, not susceptible to mechanical damage and does not present as a risk of explosion

  • Remote monitoring and diagnostics plus self-protection features



  • Deep daily discharge and sustained energy output

  • Long-life, multi-cycle design

  • Ability to value stack – frequency control and energy shifting


  • Unique system retains near full capacity over time

  • No active cooling required when operated at temperatures between 10 to 45 °C (50 to 113 °F)

  • With appropriate heating or cooling, systems can be specified to operate across a wide range of ambient temperatures 0 to 45 °C (32 °F to 113 °F)
