November 14, 2005
Overview
Partners• ORNL & INL• In collaboration with NREL• University of Tennessee• Virginia Tech• University of British Columbia• USDA & Industry
Analysis ObjectiveDOE feedstock supply analysis:• Identifies barriers to feedstock supply. • Guides core R&D in engineering solutions to overcome barriers.• Seeks out minimum cost supply options subject to quantity and quality.
Budget: Sam discussed the budget
Targets
• Target:
– Provide data on current and future feedstock supplies from agricultural residues, forest residues, and energy crops – the one billion ton vision.
– Analyze feedstock supply systems & logistics to ensure the availability of low cost biomass to meet the $35/dry ton goal.
• Guiding documents
– Roadmap for agricultural biomass feedstock supply for the U.S. (2003)
– MYTP (2003), MYAP (2004), MYPP (2005)• Timelines
– By 2007, feedstock analysis task will demonstrate that by 2015 ample feedstock will be available at $35/dry ton
• Pathways
– Agricultural residue pathway
– Perennial grasses & woody energy crop pathway
Accomplishments Forecast and Analysis
• Joint DOE/USDA Billion ton vision report (April 2005)
– Large potential biomass resource from U.S. croplands (residues, perennial energy crops)
– Most forest resources are currently available
• Analysis of grower payments for crop residues (nutrient and site operations, grower premium)
– Complicated issue given conflicting objectives between growers and processors
– Nitrogen replacements costs have risen sharply
• Revised feedstock website with updated resource data (website reconfigured by BCS)

Interim Stage Gate Overview
March 14-15, 2005
Overview of the material covered and the approach:
• Supply Forecast and Analysis – Bob Perlack– Resource estimates, grower payments, revised feedstock website
• Billion Ton Feedstock Vision – Bob Perlack (ORNL)– Results of the joint DOE/USDA feedstock supply analysis
• Biomass Supply Systems and Logistics – S. Sokhansanj (ORNL)– Integrated Biomass Supply Analysis and Logistics Model (IBSAL)

Reviewer Comments
What did the reviewers have to say about on-going analysis work?
• Supply forecast and analysis – Important task but funding was lacking. – Data development needs coordination and validation with
modeling.
• Billion ton vision ─ Need for an implementation plan and timeline.
• Biomass Supply Systems and Logistics ─ Model useful for integrating and evaluating various steps in
feedstock supply. ─ Model needs validation and peer review
DOE Response
Response to the reviewers comments
• Supply forecast and analysis – Will make new resource data and reports available on
reconfigured website. – No plans for additional activities in the Supply Forecast and
Analysis Task; related activities will be completed under Feedstock Assembly Core R&D and Feedstock Analysis.
• Billion ton vision – Will develop availability for cropland resources.
DOE ResponseActions
• Biomass supply systems and logistics
– Will accelerate validating IBSAL using existing and emerging USDA/DOE projects on straw, stover, and switchgrass over the next 3 years.
– Will collaborate with INL’s core and applied research
– Will incorporate emerging preprocessing and supply depot concepts.
• Actions taken
– Developed joint milestones between ORNL and INL
– Incorporated field data in IBSAL from USDA/Producers/INL wheat straw harvest project in Idaho.
– Incorporated data in IBSAL from Chariton switchgrass project.
– Initiated work with Imperial NE on corn stover supply logistics.
– Manuscripts for publication in Biomass & Bioenergy and Applied Engineering in Agriculture are peer-reviewed.
