Energy storage is the most exciting area in energy today. Massive amounts of energy storage are required if renewable energy is to take its rightful place on the electric grid. Invinity provides an alternative to the most common type of battery, lithium-ion because the battery technology that works so well in our pockets doesn’t work as well at the grid scale; it wears out, limits use, and even catches fire.

Manufactured as a standardized product in a factory, Invinity’s vanadium flow batteries don’t degrade, won’t catch fire, and can be operated continuously from full charge to full discharge for 25 years. Invinity has 75,000 kilowatt-hours of its modular battery systems in 82 projects across 15 countries - more than any other company in the space. We’ve deployed the largest flow battery systems in the U.S., Canada, Australia, and the UK, and are supported by the UK Infrastructure Bank, the U.S. Department of Energy, and some of the world’s leading institutional investors.

A compelling product and recent funding put Invinity in a position to grow dramatically as it addresses the global imperative for stationary energy storage. Join us as we help transform renewable energy into a stable and dependable contributor to the transition to net zero.

Invinity has operations in the UK, Canada, the U.S., and Australia and trades publicly in the UK on AIM and AQSE and in the U.S. on OTCQX. For more information about us visit our webpage.
