Clean electricity generation paired with the first grid-level sodium battery energy storage system can bring costs down to just $0.028 per kWh. The 10 MWh storage capacity is executed with sodium-ion cells that can be charged in just 12 minutes.
Time until full charge isnt really a relevant metric for utility storage, you want larger storage, which would increase full charge time. Rate of charge is what matters.

210 Ah cells to 90% in 12 minutes.
Assuming I can math early on a Monday morning:
90% of 210 is 189
189 / 12 is 15.75
So they charge at 15.75 an Ah per minute. Not sure how that compares honestly.
They’re brand new and the writer needs a number to look impressive.
And last decades
but that catched my attention for EVs.
