Matt Harper is the President of Invinity Energy Systems, the maker of vanadium-flow batteries. Matt was on the podcast in 2022 and now provides an update. A strong alternative to lithium-ion batteries, the benefits of flow batteries produced by Invinity are numerous: 30-year lifetimes with 20,000+ cycles; they can discharge 8-10 hours every day; and they have zero fire risk. Invinity’s flow batteries have the lowest lifecycle MWh delivered cost for energy storage.
