The least mature coal is lignite -- also called brown coal or soft coal. Lignite is a low-rank coal, lower in carbon and heat output. The continuing effect of temperature and pressure transformed lignite into bituminous coal -- also called hard coal or black coal. Continued organic maturity produced anthracite coal.
Of the three fossil fuels in common use natural gas, petroleum, and coal the United States has far more coal than gas and petroleum compare Figures 7-1, 8-1 and 9-1. This suggests that, when supplies of gas and petroleum become scarce, it would be possible to turn to coal
Jan 29, 2020 The coal ranking is based on levels of geological metamorphosis, fixed carbon, and calorific value. It is known as ASTM D388 05 Standard Classification of Coals by Rank. As a general rule, the harder the coal, the higher its energy value and rank.

The rank of a coal is a measure of how much change has occurred. Sometimes the term organic metamorphism is used for this change. Based upon composition and properties, coals are assigned to a rank progression that corresponds to their level of organic metamorphism. The basic rank progression is summarized in the table here.
