Chemical bonds do not store energy. Chemical bonds certainly contain potential energy, and the atoms want to move to a lower potential energy (become more stable). When methane, #CH_4#, forms, the valence electrons end up in more stable (lower energy) C-H bonds. These bonds are fairly strong, so methane is relatively inert.
