Description
REDFLOW ZBM2 (Zinc Bromide Module)
Why Redflow zinc-bromide flow battery technology?
COMPETITIVE CAPEX
100% of the capacity is usable over lifetime, with no capacity fading, therefore, no oversizing required
BEST IN CLASS LCOS
Warranted electrode stack lifetime 36,500 kWh energy delivered or 10 years (whichever comes first)
UNLIMITED SHELF LIFE
Sustains regular outages without battery damage and can be suspended, stored or hibernated from 0% to 100% state of charge
RECYCLE OR REPURPOSE
For all Redflow battery components and electrolyte
CONSTANT POWER
Charge 100% of the capacity with constant power, due to a flat voltage curve and simple one stage charge profile
COMPACT AND HIGH ENERGY DENSITY
0.34m2 (3.7ft2) with expected electrode stack throughput 40,000kWh
GREATER SAFETY
Fire retardant electrolyte, no thermal runaway due to separated tank and stack
No fire suppression system necessary or safety abuse testing required
NO ACTIVE COOLING REQUIRED
Lifetime, safety and performance are not affected by temperature
INTUITIVE WEB BASED MANAGEMENT SYSTEM
24/7 remote self-monitoring with real-time data capture accessed via the web, through the MODBUS communications system
