Lithium-ion has dominated the storage conversation.
But AI-driven power demand may create space for another category: long-duration storage.
A recent project in Switzerland plans to use vanadium flow batteries for a large AI data-centre energy system.
That is interesting because flow batteries are not trying to win the phone battery race or the EV battery race.
They are built for a different job:
longer duration
many cycles
lower fire risk
grid stability
heavy infrastructure use
As AI loads grow, storage near data centres may need to be safer, longer-lasting, and more flexible than standard short-duration batteries.
So AI demand could accidentally accelerate the market for long-duration storage.
What do you think? Will data centres become one of the first major commercial markets for flow batteries?
