Given that…
The potential energy carried by Liquid Air/Nitrogen is just over 200 Wh/kg (watt hours per kilogram).
…this is on par with battery storage, but likely doesn’t need any scarce minerals.
Conversion efficiency will be a lot lower though. Not that it matters as for a system like this the cost per KWh is the most important metric.
For.grid storage that’s good
