  2. Coal - Wikipedia

    en.wikipedia.org/wiki/Coal

    Coal can be converted directly into synthetic fuels equivalent to gasoline or diesel by hydrogenation or carbonization. [100] Coal liquefaction emits more carbon dioxide than liquid fuel production from crude oil. Mixing in biomass and using carbon capture and storage (CCS) would emit slightly less than the oil process but at a high cost. [101]

    Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen.
