Lignite or brown coal. Lignites absorbs oxygen readily on exposure to air and get spontaneous ignition. Not considered as good fuel but better then peat. They are made in briquettes after dehydration and marketed as such or after carbonization. They are used in power plants and in production of producer gas. Lignite or brown coal

· Using a discounted cash flow (DCF) model, and applying very generous assumptions to coal power, we see a net present value (NPV) in the range of €400 million, for a comparative 1,100MW power plant. The discrepancy between our DCF valuation and the assessed book values of these three coal plants suggests that RWE, Uniper and Engie will have to take another, thorough look at their .
