01
Duration Flexibility
Flow battery architectures are relevant to stationary applications where energy duration can be shaped around project requirements.
Flow Batteries
Long-duration storage
built for scalable
energy systems
Flow battery systems use external electrolyte storage and electrochemical stacks to address stationary applications where duration, scalability and system resilience shape technology selection.
Why Flow Batteries
A stationary storage pathway shaped around duration and scale
Flow batteries separate energy storage in external electrolyte tanks from power delivery through electrochemical stacks, creating a distinctive system architecture for long-duration stationary applications.
02
Independent Scalability
External electrolyte storage and electrochemical stacks create a pathway for separately considering energy capacity and power output.
03
Safety-Oriented Chemistry
Aqueous electrolyte pathways are of interest for stationary systems where operational safety and system resilience matter.
04
Long-Duration Storage Fit
A technology direction suited to renewable integration, microgrids and other stationary energy management applications.
Application Fit
Storage applications where duration influences system value
Flow battery technologies are particularly relevant to stationary use cases where renewable integration, operating continuity and project-specific storage duration matter.
01
Renewable Energy Integration
Supporting solar and wind integration where stored energy may need to be dispatched across longer operating periods.
02
Microgrids & Remote Infrastructure
Relevant to systems requiring dependable stationary storage alongside local generation and constrained grid access.
03
Commercial & Industrial Storage
Potential fit for site-level energy management, demand optimisation and resilience-oriented storage planning.
System Architecture
External storage and electrochemical conversion working together
The defining feature of a flow battery is its system-level design: electrolyte tanks, pumping and control equipment, and an electrochemical stack operating as an integrated stationary storage solution.
01
Electrolyte Storage
Liquid electrolyte is held in external tanks, establishing the stored-energy component of a flow battery system.
02
Electrochemical Stack
The stack converts stored electrochemical energy into usable electrical power within the configured system architecture.
03
Project-Based Scaling
Tank capacity, stack configuration and supporting equipment can be considered according to application duration and power needs.
Chemistry Pathways
Multiple flow chemistry routes for stationary storage
Flow battery development includes several chemistry pathways, each being considered for different balances of materials, system configuration, project footprint and deployment priorities.
01
Vanadium Redox
A widely recognised flow battery chemistry route being developed for stationary and long-duration storage applications.
02
Iron-Chromium
An alternative flow chemistry pathway of interest where abundant material systems and cost-sensitive deployment are priorities.
03
Zinc-Bromine
A hybrid flow battery direction being explored where system footprint and energy storage characteristics influence selection.
Flow Batteries in Context
System design should follow project requirements
Flow batteries are not a universal replacement for other storage technologies. Their relevance is strongest where stationary deployment, duration flexibility, safety-oriented operation and available site space align with project needs.
Project Consideration
Flow Battery Perspective
Storage Duration
Flow battery systems are particularly relevant where projects require stationary storage over extended operating periods.
Power and Capacity
The architecture allows project discussions to consider stack power and electrolyte capacity as related but distinct design factors.
Site Footprint
External tanks and balance-of-system equipment mean site layout and installation space remain important planning considerations.
Chemistry Selection
The appropriate flow chemistry depends on application requirements, supply considerations, qualification and deployment context.
