Of course it's in China. But this seems like a good development all round for enabling lower cost grid-scale battery energy storage.

"The state utility says the 10 MWh sodium-ion battery energy storage station uses 210 Ah sodium-ion battery cells that charge to 90% in a mindblowing 12 minutes."

My mind is blown.

My mind is blown.

Where on earth are they going to ever need to find a spare 100MWh in twelve minutes? Most surely there would not need to be a surplus of generation unless they blacked out an area?

Little point in recharging from non-renewables in that timescale - better to be using the generation for other purposes! Theory and practice are not necessarily the same.

So, IMO, yet another really good report spoiled by a click-bait headline?

With the rapid charge capability this sounds more applicable to transport uses - that's if it is safe enough and can be managed with no more effort than (say) an ICE.
The Helsingor-Helsingborg ferries come to mind, where you have a a robot making the charging connections and a professional crew who can be trained on what is needed and trusted to do it...
