Lignite, or brown coal, is the lowest-ranked coal, and is placed just above peat in terms of calorific value. It is not a feature of international seaborne coal trades, primarily due to its high water content (which can reach up to 60 per cent) and its lower Btu values (which average 4000–8300 Btu/lb compared with bituminous coals, which average 8500–14 000 Btu/lb).
