Invinity Energy Systems plc (OTCMKTS:IESVF) develops and manufactures vanadium redox flow battery systems designed for long-duration energy storage. Its modular battery technology enables independent scaling of power and energy capacity, making it suitable for grid balancing, renewable energy integration, microgrid stability, peak shaving and critical-load support. The flow battery chemistry’s inherent safety and ability to cycle without degradation provide reliable performance over thousands of charge–discharge cycles.
The company offers turnkey solutions that encompass system design, manufacturing, installation and commissioning, together with remote monitoring and maintenance services. Invinity’s products range from smaller commercial-scale units to multi-megawatt installations, with energy durations from two hours up to 24 hours or more. By combining proprietary electrolyte formulations with standardized hardware, the company aims to simplify project deployment and reduce total cost of ownership for large-scale energy storage applications.
Formed in April 2021 through the merger of UK-based redT Energy plc and Canada’s Avalon Battery Corp., Invinity maintains headquarters in Bath, England, and Toronto, Ontario. Its manufacturing facilities and regional offices support project delivery across Europe and North America, with a growing pipeline that includes utility, commercial and industrial customers. The company continues to pursue pilot and commercial projects in key energy markets as it works to address the global need for flexible, long-duration storage solutions.
