As a research analyst for energy storage, the cost comparisons are quite difficult.
Whilst li-ion batteries are cheaper than flow from the power perspective, as soon as you increase capacity 3-4 hours and above this is where flow batteries become competitive. They biggest problem is production at scale. Flow batteries simply don't have the capability of production that li-ion does. Therefore if demand becomes competitive, prices increase.
Around the 8-hour mark flow batteries are much cheaper than li-ion as the chemistry simply doesn't allow for this duration (not that it isn't possible, it's just expensive).
