Uses of Lignite | Lignite Energy Council

As coal is burned in a power plant to produce electricity, there is a significant amount of heat generated from the boiler that typically goes unused. However, recently many coal-fired power plants are looking to utilize this waste heat to produce ethanol. The most expensive part of an ethanol plant is the boiler required to produce the ethanol.

Cost comparison of syngas production from natural gas ...

The cost of producing UCG syngas is affected by the coal seam depth and thickness. Using the Harmon lignite bed in North Dakota, USA, as an example, the cost of producing syngas through UCG was between $37.27/TCM and $39.80/TCM. Therefore, the cost of UCG syngas was within the cost range of syngas produced by natural gas conversion.
