2. It can be easily stored and unburned or raw coal does not catches fire when exposed to external environment, but other energy sources may catch fire.
3. It exhibit high load factor, which means it is fully combustible hence, provide more thermal energy as compared to other energy sources.
4. The coal can be converted into liquid and gaseous forms. The liquid forms ensures compete combustion and no ash residue is left. No other energy source can be state convertible.
