Technical and economic assessment of fast pyrolysis, gasification and pelleting systems were performed. Required components were determined for each technology. These included pretreatment and primary conversion equipment, intermediate product and final product recovery systems, and in some cases secondary conversion equipment. Capital, operating and maintenance costs were obtained directly from manufacturers or from literature related to engineering economic assessments of similar technologies. A spreadsheet model was developed to determine required revenue, in US (2007) dollars, for each final product (electricity, bio-oil or pellets). Sensitivity of product cost to feedstock cost and plant availability was determined. Options were compared based on production cost per dry tonne of chips converted over a range of feedstock throughputs, given zero feedstock cost.

520 $a Technical and economic assessment of fast pyrolysis, gasification and pelleting systems were performed. Required components were determined for each technology. These included pretreatment and primary conversion equipment, intermediate product and final product recovery systems, and in some cases secondary conversion equipment. Capital, operating and maintenance costs were obtained directly from manufacturers or from literature related to engineering economic assessments of similar technologies. A spreadsheet model was developed to determine required revenue, in US (2007) dollars, for each final product (electricity, bio-oil or pellets). Sensitivity of product cost to feedstock cost and plant availability was determined. Options were compared based on production cost per dry tonne of chips converted over a range of feedstock throughputs, given zero feedstock cost.
520 $a Bio-oil from fast pyrolysis of woody biomass could be produced for $0 .23/liter, $1 64/tonne bio-oil or $1 31/dry tonne (dt) chips converted at a large plant (10 dry tonnes/hour), while at a small plant (2 dry tonnes/hour), bio-oil might cost as much as $0 .45/liter, $3 10/tonne or $2 41/dt chips converted. Electricity, produced via a gas turbine generator using bio-oil (from wood) as fuel, could be produced for $0 .18/kWh or $1 38/dt chips converted at a large plant, and $0 .34/kWh or $2 62/dt chips converted at a small plant.
520 $a Pellet cost was calculated at multiple capacities given two burner fuels for drying. At 6 tonnes/hour (pellet production capacity), using woody biomass as the burner fuel for drying feedstock, pellet cost was $5 7/tonne or $6 2/dt chips converted. When natural gas was substituted for biomass in drying the feedstock, pellet cost increased to $8 2/tonne or $8 9/dt chips converted. Pellet cost varied significantly with feedstock throughput, varying from $4 6/tonne or $5 0/dt chips converted at 10 dry tonnes per hour to $7 3/tonne or $7 9/dt chips converted at 2 dry tonnes per hour.
520 $a Cost of electricity from gasifier systems varied significantly with capacity, ranging from $0 .07/kWh or $6 4/dt chips converted (2 dry tonnes/hour) to $0 .04/kWh or $3 0/dt chips converted (10 dry tonnes/hour).
520 $a Conversion cost, in dollars per dry tonne of chips converted, is lowest for gasification to electricity at all feedstock throughputs, although revenues as well as costs must be considered.
