Invinity Energy Systems plc IESVF

Company Overview

Invinity Energy Systems plc is a United Kingdom–based energy storage company specializing in the development, manufacture, and deployment of utility-scale vanadium flow batteries. The company operates within the long-duration energy storage segment of the broader renewable energy and power infrastructure industries, serving customers that require non-lithium, scalable storage solutions for grid stability and industrial energy management. Its core offering is designed to support renewable energy integration, grid balancing, and resilient power supply.

The company’s primary revenue drivers are the sale, installation, and servicing of vanadium flow battery systems used by utilities, commercial and industrial customers, and renewable energy developers. Invinity positions itself as a provider of long-duration storage with advantages in safety, durability, and lifecycle performance compared to conventional lithium-ion systems. The company was formed in 2020 through the merger of RedT Energy plc and Avalon Battery Corporation, combining UK and US vanadium flow battery technologies into a single publicly listed entity.
