The energy storage sector supports the wider electricity system by enabling flexibility and balancing supply with demand. Companies within this sector are often grouped under clean technology and industrial equipment classifications. Invinity Energy Systems contributes to this segment through its focus on long-duration battery systems.

Core operations and technology framework

Invinity Energy Systems focuses on vanadium flow battery technology, a form of electrochemical energy storage that uses liquid electrolytes held in external tanks. Energy is stored and released through a controlled process that allows repeated cycling over extended periods.

The company’s activities include system development, manufacturing, installation coordination, and operational support. Its energy storage systems are used in utility-scale installations, commercial energy environments, and industrial applications where consistent power delivery is required.
