Considered giving this its own thread, but it's really just a different type of advanced battery, and has been discussed before. Via GCR:

Electric-drive cars should fuel, charging is 'dead end,' says NanoFlowcell
. . . Zero-emission cars powered by electric motors shouldn't use batteries that can be recharged, because a public charging network is "a dead end." Instead, they should use flow-cell batteries that can be "refueled" in minutes at centralized filling stations. . . .
The "dead end" quote is part of a longer statement by Nunzio La Vecchia, the Chief Technology Officer of NanoFlowcell Holdings, and inventor of the NanoFlowcell technology for energy storage. It's contained in a blog post, Full Speed Ahead Up a Dead End, on the NanoFlowcell website. . . .
If this tech can ever be commercialized, it would provide a hopefully cheaper alternative to building an H2 fueling infrastructure for FCEVs, while also providing BEVs with the rapid 'refueling' capability that they lack.
