VRB technology poised for massive growth, page-5

Hi Morry,

A good reference can be found here :
https://www.solarchoice.net.au/blog/depth-of-discharge-for-solar-battery-storage

Flow batteries (from Redflow and Imergy), for example, can be discharged to 100% without damaging the electrolyte, and theoretically can be charged and discharged indefinitely. Similarly, Aquion’s saltwater-based AHI batteries are recommended for use at 100% DoD for 3,000+ cycles.

Basically the biggest misconception corrected at this course for me, which puts VRFBs and the flow batteries mentioned above, was this DOD factor. Amp hours, kWh rating etc is not a like for like when comparing across technologies. So Flow batteries have a 'disruption' potential due to not being subject to the DOD limiting factors and being a perishable as per above. ie. the electrolyte raw ingredients can be recovered/recycled.

VRFB's IMO, have the potential to be one of the more robust solutions for providing autonomous coverage for deployed solar.
