My experience with power failures is that the refrigerator will keep the food cold enough overnight if you don't open the door.

Even so, the refrigerator could make ice during the day and be an ice chest at night. No need at all for a battery.

This.

There are numerous heating/cooling applications in which excess capacity at peak capabilities is banked for later use. Thermal energy storage for thermal energy applications is exceedingly efficient as there are no further conversion losses.

Solar power refrigeration which chills an ice block to an arbitrarily low temperature then relies on that to maintain the chilled-compartment temperature during periods of low or no power would be the obvious option.
