Mission of OBP
“The mission of OBP is to partner with U.S. industry to foster research and development on advanced technologies that will transform our abundant biomass resources into clean, affordable, and domestically-produced biofuels, biopower and high-value products. The result will be improved economic development, expanded energy supply options, and increased energy security”

Program Goals
2005: Demonstrate an integrated process for fuels production from biomass
2007: Complete technology development necessary to enable start-up demonstration of a biorefinery producing fuels, chemicals, and power
2010: Help U.S. industry to establish the first large-scale integrated biorefinery based on agricultural residues
Develop biorefinery-related technologies to the point that they are cost and performance competitive and are used by the nation’s transportation, energy, chemical, and power industries to meet their market objectives

Program Strategy
• Analysis is used to identify major cost barrier areas in each element of the program
• Research is dedicated to overcoming these barriers and reducing the cost of each process as well as the final integrated biorefinery
• Program is driven by private public partnerships to ensure integrity of the program
• Regular reviews are undertaken to ensure progress and fiduciary responsibility
• Program is based on both near term and long R&D objectives

Current Status of Ethanol Dry Mills
• Economics can be difficult– Current ethanol facilities are limited to
only two products, ethanol and DDG– Economics are highly dependent of value
of the co-product DDG– Significant energy costs are associated
with the drying of DDG– Markets for DDG are not always
favorable and will deteriorate as additional ethanol facilities come on line
![Page 12: Biomass Program Overview](https://reader036.vdocument.in/reader036/viewer/2022081504/554e999bb4c90573338b52ac/html5/thumbnails/12.jpg)
Office of the Biomass Program
Strategies for Creating Additional Value• Modify dry mills to include a quick steeping
process that allows germ recovery• Add an intermediate filtration process to
recovery non-starch derived sugars (hemicellulose)
• Develop new fermentations for utilization of five carbon sugars (itaconic acid, succinic acid, etc)
• Develop new chemistry to produce value added products from hemi-cellulose (sugar alcohols, polyols)
• Include an energy component-gasify “DDG or modified DDG” to produce fuel gas

The New Ethanol Bio-Refinery
• Build a bio-refinery based on creating the maximum value from each component associated with the feedstock
• Includes a fuel component, energy component, and value added products component
• Will allow for expansion of ethanol utilization based on solid economics
• Energy independence for the facilities could be critical to financial stability
• Be the model to build future lignocellulosic facilities

Chemicals and Materials Analysis
• Used the current petrochemical refinery as a model• Surveyed over 350 chemical/material opportunities• Reduced initial 350 to 30• Reduced 30 to 12 based primarily on the following:
– Economic considerations– Technical considerations– Building block strategies
