The results of an analysis of 22 biomass energy options are presented. Three of these involve the direct combustion of biomass to produce steam, electric power, or both. Ten thermochemical conversion processes and seven biochemical processes are considered. For each of the 22 processes, the analysis provides: a process description, including a discussion of the current status of development and projected dates of commercial operation; a block-flow diagram showing major process steps, feedstocks, products, and production rates; a process summary showing principal heat and material balances; estimates of plant facilities investment and capital costs for base, low, and high cost cases; estimates of required product revenues for each of these cases; product costs under various operating and financing conditions; and discussions of important uncertainties. Direct combustion technologies, densification of residues, and the production of rosin from Euphorbia lathyris are discussed. Thermochemical conversion to produce gases are described and analyzed. Biochemical conversion processes are dealt with. Conversion of five feedstocks to alcohol by fermentation and the production of methane from two feedstocks by anaerobic digestion are described.
