Flow batteries operate on the ability of two different species of liquids to generate electricity when they flow adjacent to each other. The long duration energy storage angle follows naturally, because the tanks that store the liquids can be sized up or down to meet capacity needs.
Flow batteries sport a number of advantages compared to lithium-ion batteries, including the ability to restart quickly after being idled for long periods of time. However, there is also a catch. If the two liquids contaminate each other, the battery degrades or destabilizes.
Ferro-Alloy Resources Ltd (LON:FAR) is developing the giant Balasausqandiq vanadium deposit in Kyzylordinskaya oblast of southern Kazakhstan. The ore at this deposit is unlike that of nearly all other primary vanadium deposits and is capable of being treated by a much lower cost process.
