Morphology
The meaning — a gaseous product derived from coal — is directly and compositionally built from 'coal' (the source) + 'gas' (a gaseous substance). This noun–noun compound follows a common, cross-linguistic pattern (source + product), so a B1 learner who knows both constituents can reasonably infer the MWE's meaning.
Etymology
Coal gas comes from the simple idea of gas made by heating coal in big ovens at a factory. This made a mix of gases that people piped into homes for 'lighting' and 'heating', so the name now means the gas made from coal.
