Relate the barriers back to the pathways where ever possible.

13. Goals & Approach
Complete technology development necessary to enable start-up demonstration of a biorefinery producing fuels, chemicals and power by 2012 at an existing or new corn dry mill.
Help U.S. industry establish the first large-scale sugar biorefinery based on agricultural residues by 2018.
Complete technology integration to demonstrate a minimum sugar selling price of $0.64/lb resulting in a minimum ethanol selling price of $1.09/gal by 2020 from ag residues or dedicated perennial energy crops.
Complete the technology integration of thermochemical processes into a sugar biorefinery to produce syngas at $3.84/MMBtu by 2030 from lignin or wood feedstocks.

14. Key Accomplishments
Development and demonstration of a new front-end pretreatment operation for a dry mill by Broin that increases the ethanol yield and produces more valuable high protein animal feed.
Demonstrated a pilot plant by ADM and the NCGA at NREL to scale-up bench results to define operating parameters involved in integrating processes into existing corn wet mills.
Recommended time for the Accomplishments slide(s): 5 min
Purpose: 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 time
To assist the reviewers evaluating your work, please include bullet comments of the key points on each slide
Though 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 hardcopies
