5. Program Goals and Relation to DOE Goals DOE has set a goal in its Strategic Plan to promote energy security through a diverse energy supply that is reliable, clean, and affordable. As a key strategy for attaining both Presidential and Department goals, the DOE Office of Energy Efficiency and Renewable Energy’s (EERE’s) Biomass Program is focused on developing biofuel, bioproduct and biopower technologies in partnership with other government agencies, industry and academia. The Biomass Program supports four key priorities of the EERE Strategic Plan: Dramatically reduce dependence on foreign oil Promote the use of diverse, domestic and sustainable energy resources Reduce carbon emissions from energy production and consumption Establish a domestic bioindustry

6. Program & Platform Strategy The IBR platform’s strategic goal is to demonstrate and validate integrated technologies to achieve commercially acceptable performance and cost pro forma targets. This goal can only be accomplished through public-private partnerships. The IBR platform is essential to achieving the Program’s strategic goal: to develop sustainable, cost-competitive biomass technologies to enable the production of biofuels nationwide and reduce dependence on oil, thus supporting the Energy Independence and Security Act of 2007, Renewable Fuels Standard for “advanced biofuels”. Government cost share of the final integrated stages of biorefinery development is essential due to the high technical risk and capital investment.

7. Platform Goals and Relation to Program Goals The scope of the IBR projects and their relationship to the three core R&D platforms (Feedstock and the two Conversion platforms) is illustrated in Fig 3-21 from MYPP. While project emphasis is on the biorefinery and its conversion processes, the business plan that provides the project vision also includes strong feedstock supply components. Currently, the Program priority remains focused on enabling biorefineries to efficiently convert lignocellulosic biomass into ethanol and other biofuels at the commercial and demonstration scale. New Funding Opportunity potentially allows a broader range of feedstocks in addition to lignocellulosics (e.g. algae, sugarcane, sugar beets) at the pilot and demonstration scales.

8. Platform Strategy and Pathways The IBR platform’s work breakdown structure addresses and supports all pathways. The WBS under each pathway is comprised of three major elements: 1. Demonstration and deployment includes all the major integrated biorefinery projects, collectively representing the largest portion of the overall platform budget. 2. Technical assistance covers smaller R&D projects that are identified by industry partners and stakeholders as critical to improving existing biorefinery operations. 3. Analysis covers a broad range of technical, economic and environmental topics, and is used to assess the individual progress of the integrated biorefinery projects as well as the collective status and progress of the bioindustry.

9. Cost Targets  The 2012 performance goal of the Integrated Biorefineries platform is to demonstrate the successful operation of three integrated biorefineries across various pathways.  By 2017, mature technology plant model will be validated for cost of ethanol production based on pioneer plant performance and compared to the “nth plant” target of $1.33/gallon.

10. Success Factors/Showstoppers Research into near-term technical improvements that can be implemented within the existing industry infrastructure and are a priority of the industry. Future RD&D projects in this area would need to have broad applicability to a variety of biomass feedstocks that represent a significant increased market potential for biofuels production. Technical Barriers addressed: It-A. End-to-End Process Integration It-B. Commercial-Scale Demonstration Facilities It-C. Risk of Pioneer Technology It-D. Sensors and Controls It-E. Engineering Modeling Tools Market Barriers addressed: Im-A. Political and Competitive Environment Im-B. Lack of Feedstock Infrastructure Im-C. Lack of Consideration of Externalities Im-D. Biorefinery Plant Economics Im-E. Lack of Industry Standards and Regulations Independent Project Analysis and an Independent Engineer are used to identify specific project risks, risk mitigation, and project management/oversight.

11. Milestones IBR has project level milestones, platform level milestones, and joule targets for the Platform. The project level milestones will be covered in the PI presentations. The Platform level milestones are generally based on: – Downselect: Based on bench scale evaluation of viable processes/technologies, select the process design configuration that will move forward for demonstration in an integrated pilot plant. – Demonstrate: At pilot scale and beyond, verify that the unit operations operate as designed and meet the complete set of performance metrics (individually and as an integrated system). – Validate: At pilot scale and beyond, ensure the process/system meet a desired expectations/original intent. Validation goes beyond just meeting all of the performance metrics; it is an assessment of whether the system actually fulfills/completes a portion of the program effort so that the Program can move on to the next priority.

12. Budget Specific, high level “joule targets” for previous and current budgets are: FY 2007 - Complete a preliminary engineering design package, market analysis, and financial projection for at least one industrial-scale project for near term agricultural pathways (corn wet mill, corn dry mill, oilseed) to produce a minimum of 15 million gallons of biofuels per year (as mandated by the Energy Policy Act. [MET] FY 2008 - Approve a final engineering design package of at least one commercial scale biorefinery capable of processing up to 700 metric tones per day of lignocellulosic feedstocks. The approved design package must address any findings from an independent engineering review to validate contractor costs and scheduled timeline. Validation of biorefinery concepts will reduce technological risk and attract additional sources of capital to accelerate deployment and oil displacement. [MET] FY 2009 – Initiate construction of at least one commercial-scale biorefinery project (designed to 700 ton per day feedstock processed) including orders for long lead items, vendor packages, and structural steel. Validation of biorefinery concepts will reduce technological risk and attract additional sources of capital to accelerate deployment and oil displacement. Approve engineering design of one additional commercial scale biorefineries (two in total) including orders for long lead items, vendor packages, and structural steel. The result of this will ultimately be to complete construction by 2011 Approve preliminary engineering design package, market analysis and financial projections for at least four demonstration scale biorefineries (designed to 70 ton per day feedstock) selected in FY 2008. These efforts work toward validating the $1.33 per gallon cost target in integrated biorefineries by 2017.

14. Feedback From Prior Peer Review More deployment has led to more industrial involvement and progress towards commercialization - positive outcome There should be more integration with the Feedstock Platform and logistics - delivery 365 days per year Systems integration, IPA and Independent Engineer participation is essential to analyze and reduce risk More focus is needed on the following: – Reduced water consumption – More unit operation development and feedstock pre-processing – Plant wide footprint to reduce energy consumption Consolidated bio-processing needs to be addressed in future solicitations Better link between fundamental science (ethanologen) and deployment activities More focus on cross-cutting technologies
