I think youre misunderstanding one thing, which is that the ice is a replacement for batteries.

No, I understood that.

The thermal battery is also far smaller, cheaper, and more robust than a lithium battery and it won’t deteriorate with repeated cycling.

The repeated cycling thing is the only advantage I see to this, the ice block will not be smaller than a normal battery array.

So while its very niche, it is quite effective for home air conditioning.

Is it?

Is it?

92kWh/m^3 of energy is a lot of cooling. It'd be hard to not be effective.

These one ton blocks of ice would provide 12,000 Btu/h of cooling for 24hours.

So a block of ice about the size and weight of a car to cool one house... I'm really just not following how any of this is worthy of attention?

size and weight of a car

blocks of ice measuring 4 ft × 4 ft × 2 ft.

This you?

Because 32 cubic ft is about the volume of most residential AC units.

lol is that the size of your dwelling? That size (4 ft × 4 ft × 2 ft) get's you 12k btus which is not enough for any house lol.
