Energy storage is one of the most exciting areas in energy today. Massive amounts of storage are required if renewable energy is to take its rightful place on the electric grid. Invinity provides an alternative to lithium-ion batteries because the technology that works so well in our pockets doesn’t work at 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 operate continuously from full charge to full discharge for 25 years. With over 75,000 kilowatt-hours deployed across 82 projects in 15 countries, we lead the industry in flow battery technology. Supported by global investors and government agencies, we’re scaling rapidly to meet the world’s demand for safe, long-duration energy storage.

Join us as we transform renewable energy into a stable and dependable contributor to the transition to net zero.
