WHAT IS IT?
The Crazy Dream Of A Flow Battery Electric Vehicle Is Not So Crazy Any More.
“slurry electrode iron flow batteries” being developed at Case Western Reserve could someday be simple refrigerator-sized units placed at the end of a city block or even in the basement of a house to store wind- or solar-generated energy for 10 to 24 hours,
For those of you new to the topic, the “flow” in a flow battery is literal. The idea is to produce electricity by making two specially treated liquids flow adjacent to each other. Typically the liquids are separated by a thin membrane, though researchers have been working on advanced tech without one.
With the right tweaks, flow batteries can be inexpensive, and they can be made with raw materials that are abundant, eco-friendly, and shielded from geopolitical complications.
