Book excerpt: This report presents a cost analysis of second generation Ethanol production from corn stover via 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: corn stover pretreatment with dilute acid and ammonia conditioning; enzymatic hydrolysis; and fermentation. Electricity is also generated as by-product. This report examines one-time costs associated with the construction of a United States-based plant and the continuing costs associated with the daily operation of such a plant. More specifically, it discusses: * Capital Investment, broken down by: - Total fixed capital required, divided in production unit (ISBL); infrastructure (OSBL) and contingency - Alternative perspective on the total fixed capital, divided in direct costs, indirect costs and contingency - Working capital and costs incurred during industrial plant commissioning and start-up * Production cost, broken down by: - Manufacturing variable costs (raw materials, utilities) - Manufacturing fixed costs (maintenance costs, operating charges, plant overhead, local taxes and insurance) - Depreciation and corporate overhead costs * Raw materials consumption, products generation and labor requirements * Process block flow diagram and description of industrial site installations (production unit and infrastructure) 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
