Impact of Combined Heat and Power on Energy Use and Carbon Emissions in the Dry Mill Ethanol Process
Along with increased production efficiencies and expanded fuel capabilities, combined heat and power(CHP) is increasingly being considered as an efficient energy services option by many ethanol plant owner and financing groups. CHP is an efficient, clean, and reliable energy services alternative, based on generating electricity on site. CHP avoids line losses, increases reliability, and captures much of the heat energy normally wasted in power generation to supply steam and other thermal needs at the site. CHP systems typically achieve total system efficiencies of 60 to 80 percent compared to only about 50 percent for conventional separate electricity and thermal energy generation. By efficiently providing electricity and thermal energy from the same fuel source at the point of use, CHP significantly reduces the total fuel used by a business or industrial plant, along with the corresponding emissions of carbon dioxide (CO2) and other pollutants.
