‘Workhorse of batteries’ could give California tribe’s new clean-energy microgrid a jolt
Zulch calls vanadium redox flow batteries like the one his company is devising for this grid “the workhorse of batteries” since they don’t have the same fire risks as lithium batteries and can last for more than two decades. However, they do take up a lot more space—Zulch says their redox flow battery units are about the size of a shipping container—so they work best in situations where there is significantly more room available, compared to something like a cell phone battery.
