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.
I’m curious what the temperature resiliency is for sodium-ion batteries. I had a power outage recently where I was relying on a lithium-ion battery. As the temperature in the house plunged, it because so inefficient that charging a single phone overnight drained a quarter of the battery.
It was slightly above freezing in the house, so definitely not operating at peak efficiency. From a brief search, it looks like sodium-ion does have a similar temperature sensitivity, though it may be to a different degree.

I don’t have any data on sodium-ion.
