nickel metal-hydrogen battery

Brazil-based VedantaESS has agreed to buy EnerVenue’s energy storage vessels for use in utility-scale, distributed-generation and isolated microgrid applications.

Unlike lithium-ion battery cells, EnerVenue’s nickel metal-hydrogen technology showed no fire propagation during induced thermal runaway in UL battery safety testing.

Researchers in China have ranked some of the most commonly used battery chemistries according to parameters deemed important for grid-level storage. The team gave a score in each category and determined a winner – and it wasn’t lithium-ion.
