His main element is carbon WebSubbituminous coal has a higher heating value than lignite. Subbituminous coal typically contains 35%–45% carbon, compared with 25%–35% for lignite. About 46% of the coal produced in the United States in 2024 was subbituminous. Bituminous coal contains 45%–86% carbon and has two to three times the heating value of lignite.
