Preparation of a Cost Data Bank for DOE/Biomass Energy Systems Branch. Third Quarterly Progress Report, April 1-June 30, 1979

摘要

This study deals with the preparation of a biomass conversion technology and cost data bank for the Biomass Energy Systems Branch (BES) of DOE/Solar. When completed, it may be used with an appropriate methodology to analyze the complex issues of research program planning and analysis. In addition, future market penetration of BES products may be projected, and the options available to the federal government to influence the outcome of BES products marketing may also be examined. A total of 21 biomass conversion technology options (13 thermochemical and 8 biochemical) have been selected for inclusion in the data bank. These options cover the production of electric power, steam, gases, liquids, and solid fuels from biomass. The majority of the options are believed to be available now or in the near term. A consistent methodology for construction of the data bank has been developed. For each option, the most up-to-date process/product data are gathered and analyzed. A base case is established to generate estimates for plant investments required, operating cost, and product cost. The estimates are then examined systematically to identify and quantify the uncertainties. The uncertainties are combined using statistical methods to produce error band estimates. Technical and economic analysis has been completed for the following options: power generation, steam generation, co-generation, liquids from pyrolysis, densification, and ethanol from wood. Among the options nearing completion are catalytic liquefaction, medium-Btu gas, low-Btu gas, methanol, ethanol from sugar crops, and ethanol from corn. The available results are summarized.
