Curious. If a photon does not have enough energy to emit an electron from a metal surface, where does that energy go? Does it get stored as potential energy? Or does it simply just escape and become irrelevant?

It will typically heat up the metal. And the metal will 'give off' heat as IR radiation to the surroundings.

Due to the conservation of energy, the energy is not irrelevant and just disappear. It may heat up the metal or take another form. Energy is neither created or destroyed.
