Justify the statement 'Hydrogen is a cleaner and better fuel than $CNG$'.

(N/A) Hydrogen is considered a cleaner fuel than $CNG$ because its combustion produces only water vapour $(H_2O)$,which is non-polluting and does not contribute to greenhouse gas emissions or particulate matter. In contrast,$CNG$ (Compressed Natural Gas) contains hydrocarbons,and its combustion releases carbon dioxide $(CO_2)$ and other pollutants. However,hydrogen is not widely used in daily life due to its highly explosive nature,which makes its storage and transportation extremely difficult and hazardous.
