2005 OBP Biennial Peer ReviewSelective Harvest
Kevin L. Kenney, Christopher T. WrightBiomass Feedstock Interface PlatformNovember 14, 2005
OverviewWork ObjectiveObjective Decrease 2005 cost to $35/dry ton by 2015 for the purpose reducing sugar cost by almost 2 cents per lb, for all Billion Ton Vision FeedstocksBudget About $2M per year from 2004 -2006Current Partners National Laboratories, Universities, Equipment IndustryDeveloping Partners Agribusiness Commodity Companies, Regional Feedstock Centers Partnerships, Feedstock Interface to Biorefining PartnersNote: Sugar conversion cost estimate reductions based on the 2005 post-enzyme subcontract conversion case.

Approach1. DOE Multi-Year Technical Plan Barriers for Feedstock Supply can be grouped into:Cost - $35 / try ton (Operational and Capital Costs)Quality dockage, composition, conversion efficiency (selective harvest, fractional milling, in-storage fractional conversion)Quantity biomass types (Billion Ton Study)2. Develop preprocessing based feedstock supply systems that interface biorefining conversion processes to feedstock resources:Corn StoverCereal StrawSwitchgrass

Summarized Reviewer CommentsThis project was categorized by the reviewers as engineering tool development rather than an R&D project subject to Stage-Gate decision-making. It was observed that the modeling tool(s) were general and that increased focus on biomass and biomass-related applications would be of greater benefit.Recommendation: It is important to identify biomass feedstock characteristics that are important to a biorefinery and show how these tools can help provide feedstock with these characteristics more cheaply/efficiently. The question of where processing is most effectively done needs to be answered. What are the trade-offs on where you effect the separations? These questions need to be answered and the tool tied directly to real-world equipment development.
DOE ResponseProject focused on the relevance to a specific biomass application selective harvestIdentified necessary approachIdentified theoretical targetsIdentified practical targetsDeveloped and applied a computational engineering tool to achieve practical targetsField tested functionality of engineered solutionAnalyzed residue fractions to establish the value of selective harvest not according to theoretical separation targets, but according to actual separations accomplished with a grain combine

Ongoing TasksObjective: Design a baffle to accomplish high-fidelity residue separation
Approach: Develop virtual engineering model to design baffle separator by simulating baffle performance to (1) determine the effect of the baffle on the airflow of the combine cleaning system and (2) predict the effectiveness of the baffle in separating the residue streams. Model Components:Combine geometryBaffle design canvas (CAD tool)Embedded, interactive CFD model of the single-phase air flow of the combine cleaning systemComputational Engineering Approach
Ongoing TasksBaffle increased the chaff stream purity from 64% to 93%The 7% straw is result if spearing through the concavesShows that chaff mixing with the straw is not a problemTesting

Ongoing TasksStraw fraction has highest theoretical ethanol yieldNo Baffle: no value of selective harvest at this level of fractionationBaffle: 11 gallons of ethanol per dry ton difference between chaff and straw streams significant differential value of selective harvestWhole stover ethanol yield approximated by dashed line. 0.5% increase for no-baffle straw, 3.3% increase for baffle strawBaffle: Do not loose higher value straw in chaff streamResults
Summary and Future Work
Platform Level Technical Outcomes Is the Platform performing well?Is the Platform managed in a way that facilitates reaching its end goals?Do the Platform goals support the Programs goals?Are there any outlying projects that do not seem to support the Programs goals?
The purpose of this slide is to provide some context for evaluating the current work in this barrier element focusing on accomplishments. The information in the left column describes the magnitude and timing of the investment this area. The information in the right column describes the players.Please indicate the degree to which the work on this barrier supports the Platforms goals and objectives of the Multi-Year RD&D plan.Please indicate the relevance to Platform Objectives
Recommended time for this slide: 1 min(General)Purpose: Describe how the program has addressed the comments received in past reviews.
Purpose: Describe how the program has addressed the comments received in past reviews.
Tasks to accomplish/overcome the barriers issuesPurpose: Describe the most important technical accomplishments and results obtained in the last year. Whenever possible, describe the significance of the accomplishments by relating the results to the appropriate DOE targets and milestones from the MYPP. Include sufficient slides to explain what was done leading to the technical accomplishments Please limit your slides to the time you have available you will not be allowed to go over your allotted timeTo assist the reviewers evaluating your work, please include bullet comments of the key points on each slideThough your presentation will be in color, it is best to choose colors and data symbols so that they can be easily distinguished in black and white for those reviewers with hardcopiesTasks to accomplish/overcome the barriers issuesPurpose: Describe the most important technical accomplishments and results obtained in the last year.
