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.

    You are not completely right. 1 C means it can (theoretically) be charged in 1h. Regardless of the capacity.

    10 C means it can be charged in 1/10th of an hour.

    To get the maximum current, multiply the capacity by the C rating.
