Lignite which is the least energy intensive form of coal according to some definitions is not coal at all In fact it is considered a dirty energy source lying somewhere on the spectrum Lignite Lignite generally yellow to dark brown or rarely black coal that formed from peat at shallow depths and temperatures lower than 100 176 C 212 176 F It is the first product of coalification and is intermediate between peat and subbituminous coal according to the coal classification used in the United

Focus on Carbon Capture Utilization Storage CCUS The Lignite Research program is focused on solving both regulatory and economic challenges faced by the coal industry These challenges result from regulations to reduce regional haze or CO2 but also from market dynamics exacerbated by an uneven field in power markets For every state dollar invested in R D more than nine dollars are Even at that there is a growing global campaign on the outright utilization of lignite and coal in general in particular for ANY purpose at all due to its high potential for GHG emissions That

Recent development in lignite investigation It is worth mentioning some interesting utilization advantages of lignite over higher rank coalBecause of its high reactivity which is due in part to high oxygen content lignite does not have to be ground as finally as higher rank coal to ensure complete combustion in pulverised coal systems Advantages for gasification and liquefaction are 220 to 280xJ and coal utilization occurs at a rate of 36TW2 4 Even if the utilization Even if the utilization rate doubles the coal resource will last several thousands of years
