Sub-bituminous coal is a lower grade of coal that contains 35–45% carbon. The properties of this type are between those of lignite, the lowest grade of coal, and those of bituminous coal, the second-highest grade of coal.[1] Sub-bituminous coal is primarily used as a fuel for steam-electric power generation.
