About CHARG Energy
CHARG Energy is an engineering-led company that develops and sells advanced flow battery, microgrid, and electrochemical energy systems for high-reliability applications.
We combine deep expertise in electrochemistry, system architecture, and large-scale infrastructure to deliver long-duration storage platforms designed for industrial, utility, and mission-critical environments.
Our work spans laboratory validation, full-system architecture design, and field deployment - ensuring technologies are technically robust before commercial scale-up.
Our Approach
CHARG operates across three integrated layers of development:
• Laboratory research and electrolyte optimisation
• System architecture and stack integration
• Field-based validation and deployment
We collaborate with research institutions and industry partners to rigorously test, de-risk, and refine advanced energy technologies prior to full commercial rollout.
Our Focus Areas
Flow Battery Systems
Modular long-duration storage architectures engineered for high reliability.
Microgrids & Power Systems
Resilient on-grid and off-grid configurations for industrial and remote environments.
Electrochemical Technologies
Advanced electrolyte and electrochemical process development for energy storage and mineral extraction.
Research & Development Capability
CHARG maintains a strong internal R&D capability supported by world-class expertise in flow battery technology and advanced electrochemical systems.
We work in collaboration with leading research institutions and technology partners to accelerate validation and deployment of next-generation energy storage platforms.
In partnership with Queensland University of Technology, CHARG is developing and field-validating advanced long-duration storage solutions for both the Australian and US markets.
MEET OUR TEAM
Backed by over 200 years of combined experience, CHARG Energy’s team includes some of the most experienced engineers and practitioners in flow battery systems, electrochemistry, and large-scale energy infrastructure.
With decades of hands-on work spanning system architecture, stack and electrolyte development, manufacturing, and deployment, the team has played a direct role in advancing long-duration energy storage technologies - and continues to actively develop the next generation of flow battery and electrochemical energy systems today.
