Another Zinc-Air battery company.  Have a three year trial project in NY at a claimed $45/MWH.   Company is targeting long duration discharge to gain this price point >8 hours.   Could be a good daily renewable energy "extension" product - pushing solar or wind into longer generation periods.  

This technology appears to be similar to flow batteries with a chemical storage tank that is enlarged to extend durations.  In addition there are lower cost materials in the construction.  They do not mention the round trip efficiency so that could be an issue.

That picture looks like the MGX Renewables Zinc Air battery.

Very promising technology for essential grid services at a very attractive price point.

Richard - not familiar with all of the players - you and I agree - promising.  The big question is how can they get traction, they will not have the automotive support like LiIon.  Telsa published their cost for storage at $156/KWH - amazing!
