Cellulosic Ethanol From Switchgrass Cost Analysis Ethanol E81a

This report presents a cost analysis of second generation Ethanol production from switchgrass based on a biochemical conversion process. The process examined is similar to the process reported by the National Renewable Energy Laboratory (NREL). This process involves the following steps in the production of hydrous Ethanol: biomass pretreatment with dilute acid and ammonia conditioning; enzymatic hydrolysis; and fermentation. Electricity is also generated as by-product. This report was developed based essentially on the following reference(s): Humbird, D., et al., "Process Design and Economics for Biochemical Conversion of Lignocellulosic Biomass to Ethanol, " Report NREL/TP-5100-47764, National Renewable Energy Laboratory (NREL), 2011 Keywords: Ethyl Alcohol, Bioethanol, Lignocellulosic Biomass, 2nd Generation, Cellulosic Sugar, Hemicelluloses, Cellulose
