Metallurgical coal is more scarce and valuable than thermal coal, so in practice metallurgical coal is rarely used to generate electricity. Metallurgical coal is also common-ly referred to as coking coal. Coking coal has physical properties that when heated cause it to soften, liquefy and then resolidify into a harder substance known as coke.
