@lenzgr also #SodiumBatteries or rather #SaltwaterCells are not only going to beat #Lithium in terms of #pricing but also are way less hazardous and energy intensive to manufacture..

Not to mention they'd really make sense next to rectifiers for #OffshoreWind, #PV / #Solar and other #RenewableEnergy sources where they could buffer away peaks and fluctuations as well as increase total output on average...
