ZBM 2
Why Zinc-Bromide Flow Battery Technology
COMPETITIVE CAPEX
100% of the capacity is usable over lifetime, with no
capacity fading therefore no over sizing required
COMPACT AND HIGH ENERGY DENSITY
0.34m2 (3.7ft2) with expected electrode stack
throughput 40,000kWh
BEST IN CLASS LCOS
Warranted life of 10 years or 30MWH energy throughput based on
100% daily discharge - 3000 cycles at 100% depth of discharge
GREATER SAFETY
Fire retardant electrolyte, no thermal runaway due to
separated tank and stack
UNLIMITED SHELF LIFE
Sustains regular outages without battery damage and
can be suspended, stored or hibernated from 0% to 100%
state of charge
No fire suppression system necessary or safety abuse
testing required
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
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
ZBM MANUFACTURED BY FLEX for REDFLOW
Building blocks to advanced energy storage features
100% depth of discharge is perfect for
intermittent energy sources with no battery
damage from regular power outages.
TELECOMMUNICATION
APPLICATIONS
Redflow batteries are suited to storing
long-duration and renewable energy during
times of high generation and discharging it
during peak periods.
