A recent Harvard study found that flow batteries can run for more than a decade with little maintenance. Interesting piece, but reality is already better than the lab because ViZn Energy's Zinc-redox flow battery is commercially available and offers a 20-year performance guarantee - no lithium ion storage system can match that. Add to that the inherently safe, non-toxic Zinc-Iron chemistry, ViZn's systems don't require HVAC, and the fact that it has the ability to perform both power and energy services in one system and the total lifetime system costs become rather attractive versus lithium-ion storage systems.
