Energy & Grid Resilience
St George Group supports grid-scale and behind-the-meter energy resilience systems designed for environments where power stability, safety, and long-duration operation are mission-critical. Our focus is on integrating proven energy storage architectures into complex infrastructure, utility, and high-risk operational settings.
The systems illustrated below represent containerized redox flow battery (RFB) configurations used globally for grid stabilization, microgrids, renewable smoothing, and emergency power continuity .
Redox Flow Battery Systems for Critical Infrastructure
Redox Flow Battery (RFB) systems store energy in liquid electrolyte tanks and deliver power through electrochemical cell stacks. This architecture enables independent scaling of power and energy capacity, making it well suited for grid and infrastructure resilience applications .
Key operational characteristics include:
- Real-time state-of-charge monitoring through voltage measurement
- 100% depth of discharge with no cycle life limitation
- Long operational lifetime (20+ years)
- Non-flammable electrolyte and materials, offering extremely low fire risk
These attributes make RFB systems appropriate for deployment in safety-sensitive and continuously operating environments.
Containerized, Scalable System Architecture
The images demonstrate containerized RFB modules designed for efficient transportation, reduced installation footprint, and flexible expansion. Standard module configurations range from 250 kW output with 3–6 hours of storage, allowing systems to be scaled from megawatt-hour to multi-tens-of-megawatt-hour installations .
Two-story system layouts reduce land requirements while supporting higher output density, an advantage in constrained or secured sites.
