Presentation Transcript

  1. Feedstock Costs and Availability for a Proposed Co-gasification Plant in the Western United States Haley Thompson ‘11

  2. Logging Residue Removal Cost Analysis • Using the Forest Residue Cost model • Assuming that the truck must travel roughly 2 miles on recently built or spur roads to access the location of the grinder to process the biomass in the woods. • Assuming an average of 50 miles to transport biomass to Missoula • Use Knuckleboom loader, tub grinder at the site, truck w/pup to transport ground biomass • Use cost indices to analyze results in 2007 dollars

  3. Rail Transport Cost Analysis • Find BNSF Price Quotes for transporting coal and biomass to/from Western Montana • Use BNSF Mileage calculator to determine the distance between origin and destination to calculate fuel mileage surcharge • Fuel surcharge from BNSF Rules Book 6100 item 3381.

  4. Total cost for Biomass Transportation from Western MT to CO/WY

  5. Total Cost for Coal Transportation from WY to Western Montana EIA Annual Coal Report 2008, Table 34

  6. Cost Comparison Estimations • Reasons for the rate differences • Coal is more dense: 100 tons/car coal vs. 30-40 tons/car biomass • Biomass must be transported significant distances on trucks as well as rail whereas trains go directly to many mines • One issue not addressed in this presentation is the fact that values are calculated for bdt of biomass when in fact air dried biomass has a moisture content of 15-20% which would decrease the amount transportable in one railcar and also effect the energy equivalent for the fuel
