Benefits for coal power plants with co-located ethanol production
Co-locating biomass-based ethanol production facilities adjacent to coal-fired power plants could provide attractive economic and environmental benefits for these power plants, including reduced fuel costs, as well as reduced NOx and greenhouse gases (GHG) emissions. Hydrolysis technologies for producing ethanol from renewable, low-cost cellulosic biomass (such as agricultural residues, wood chips, grass clippings or waste paper) are now in the initial phase of commercial deployment. The lignin by-product from these ethanol production facilities is an energy-dense renewable fuel that can be cofired in coal boilers; in turn, the coal plants could provide process steam for the ethanol plants. Significant NOx and GHG emissions reductions (20% to 30%) may be possible if the lignin is cofired as a water slurry. New NOx emissions trading programs and emerging plans for renewable portfolio standards could enhance the value of this approach.
