Vanadium batteries last decades before degrading, use low levels of carbon dioxide and never explode, making them an intriguing alternative to lithium. Led by co-founder Avishek Kumar, VFlowTech is developing vanadium-based EV charging stations and shipping modular units around the world for microgrid or off-grid applications. Its VFlowTech Power Cubes store solar and wind energy, and are transforming the lives of users in rural South Asia and Africa.
