Morphology
The meaning 'energy stored in the bonds of chemical compounds' is directly and compositionally derived from 'chemical' (relating to chemicals or chemistry) modifying 'energy' (usable power). This modifier+noun pattern is regular and cross-linguistically common (e.g., Spanish energía química), so a B1 learner who knows both constituents can readily infer the MWE meaning.
Etymology
The term chemical energy gives a picture of tiny parts in a substance holding power like a wound-up spring. When the bonds between those parts break the power is 'released', so the term means the energy 'stored' inside a substance that can come out in a chemical 'reaction'.
