Abstract | Virtually all of the ethanol used for transportation has been produced from corn. During the period of fuel ethanol growth, corn farming productivity has increased dramatically, and energy use in ethanol production plants has been reduced by almost half. The majority of corn ethanol plants are powered by natural gas. In this paper, we examine nine corn ethanol plant types--categorized according to the type of process fuels employed, use of combined heat and power, and production of wet distiller grains and solubles. We found that these ethanol plant types can have distinctly different energy and greenhouse gas emission effects on a full fuel-cycle basis. Our results show that in order to achieve energy and greenhouse gas emission benefits, researchers need to closely examine and differentiate among the types of production plants used to produce corn ethanol. |
