Yes, I didn't say the energy is stored in the bonds or is released by breaking bonds. I was referring to the fact that photosynthesis (or electrolysis) is used to separate the oxygen from the carbon/hydrogen in H2O or CO2. That's where the energy is stored (in the separation of the fuel from the oxygen).
