Will that even be relevant or is the important part that energy is stored ?
The electron imbalance between the two plates is the stored energy. You start with equal amount of electrons on both plates and that is a discharged capacitor and in a charged capacitor you will have excess of electrons "parked" in one plate and deficit of electrons in the other plate.
Even when you remove the capacitor from the circuit this imbalance remains and that is how energy is stored.
To discharge you can just short the two plates and electrons form the plate with excess will travel through the wire to the plate with deficit until number of electrons is again equal on both plates.

That heat is radiated by a resistive device like the wires in this example and a pure resistor is not storing electrical energy.

Yes.

You didn't answer either question. Are you saying there is no physical location?
You didn't answer the second question at all either.
Do you know what a discussion is?

Is it a trick question? Inside .. ???

??? Have I not mentioned electrons that are a physical particle and they have a charge.
It is almost like you are denying that capacitors are an energy storage device.
We are discussing electrical energy not thermal energy.
The infrared photons traveling from one wire to another (or one capacitor plate to another) have nothing to do with electric current.
Yes a few infrared photons from one wire will get to the other wire and slightly heat the other wire but is completely irrelevant for this discussion.
Even if the wire is so hot that it glows in visible light it will not transfer electrical energy to the other wire. It will need to be UV or above in order to displace electrons.
Radio waves are on the other side of the infrared closer to DC.
