  1. 1. Biorefineries of the Future Envisioned byDOE’s Biomass Program CDMA Fall 2005 Meeting New Revenues from SustainableIndustrial Biotechnology and Renewables September 28, 2005 Cynthia Riley, P. E. Lead Systems Integrator
  2. 2. Outline• Why Biomass ?• OBP Overview – Biomass Resources – Biorefinery Deployment Pathways – Sugar Lignin Conversion Platform – Systems Analysis incl. Life Cycle Assessment – Stage Gate Approach – Deployment Barriers• Government Policy/Initiatives – Energy Policy Act of 2005 and OBP NOPI – Other Federal Agency Collaborations
  3. 3. Unique Role of Biomass While the growing need for sustainable electric power can be met by other renewables… Biomass is our only renewable source of carbon-based fuels and chemicalsAddressing National Needs•Energy Security and diversity •Charts on needed capacity, high utilization rates, high imports, national feed stock availability •Availability and price of imports •Presently 1.6 billion gal of ethanol produced yearly, Replacement of MTBE with ethanol will double that amount (6 million gal of bio-diesel) •9,000 MW Biobased power today with an additional 1,000 MW from the Forest and Paper Products industry•Environmental Concerns •Waste Utilization •Livestock and poultry waste •MSW •Biogas/methane from land fills and the availability of landfills •Direct or co-firing with bio substantial reduction in greenhouse gasses •Near zero CO2 emissions due to closed carbon cycle •10 –20% reduction in NOx (gasification coal co-firing poplar) •Reduce SO2 emissions by 80-97% •Low sulfur fuel •Complement forest management practices•Rural Economies •If $20/ton of biomass, increased biomass use represents over $4 billion per year in new revenues for rural economies. If two thirds of the idle land were used to grow energy cropos those 35 million acres could product between 15 and 35 billion gallons of ethanol each year. •Over the past 20 years, investors have installed 730 bioenergy electric generating facilities, and 58 ethanol production plants. Investments in the residue-based industry have created 66,000 jobs and a net annual income of $2 billion.DELIVERED COST OF FUELS/ENERGY, $$/MMBTU:(mostly AEO 2001)Electricity Mix = 19.5 Coal = 1.23 Nat Gas = 4.05 Biomass (dry) = 2.81 Ethanol = 14.42 Gasoline = 9.45Oil = 7.44The need for bioenergy and bioproducts is driven in large part due to increased growth in electric capacity requirements, increased reliance on imported oil, and the need to boost farm income and reverse the decline in the U.S. agriculture trade surplus.Electric Power - EIA projects that about 1300 new power plants could be needed by 2020 to provide the estimated 1060 GW of electricity generating capacity that will need to be in place by that time. There is a major shortfall that needs to be filled. Current capacity levels are 754 MW. Cumulative planned additions through 2020 are only 14.8 GW where as cumulative planned retirements are 69.4 GW. (Source: EIA/Annual Energy Outlook Table A9)The Opportunity? There are over 370 GW of unplanned capacity which will need to be filled. There are significant opportunities for biomass power technologies to fill part of this gap.Fuels and Products - New sources of domestic fuels are needed. The U.S. is becoming increasingly reliant on both imported crude oil and imported refined petroleum products.•Domestic crude oil production is projected to decrease from nearly 6 million barrels per day currently to about 5 million barrels per day in 2020. Crude oil imports are about 8.9 million barrels per day and account for about 60% of our crude oil supplies. This is projected to increase to over 12 million barrels per day by 2020 and account for 71% of our total crude oil supplies.•The U.S. is becoming increasingly reliant on imported refined petroleum products. Imports of refined petroleum products are projected to increase 6% annually from about 1.3 million barrels per day at present to over 4 million barrels per day in 2020. Compounding the problem of dependence upon imported petroleum products, is increasingly tight petroleum refinery capacity in the U.S. Refinery utilization rates have been above 91% each year since 1993 and are projected to remain between 92% and 95% over the next 20 years. (Source:EIA/Annual Energy Outlook Table A11 and Petroleum Supply Annual Table S1)The Opportunity? Increased production of domestic biofuels can help to offset a portion of crude oil, petrochemical, motor gasoline, and blending component imports.Agriculture - Under current farm legislation and programs, assuming no supplemental payments, net cash farm income in 2001 is projected to be its lowest since 1994 and about $4 billion below the average of the 1990s.  This is due primarily to a continued rise in production expenses and a decline in government payments.  The U.S. agricultural trade balance with the rest of the world increased by almost $11 billion between 1990 and 1996, then declined by $14.4 billion between 1996 and 2001. This drop in the volume of exports wascompounded by a sharp decline in domestic commodity prices. These two factors have combined to severely depress net farm cash incomes since 1997. (Source: Economic Research Service, USDA)The Opportunity? Increased demand for bioenergy and bioproduct feedstocks, in addition to ethanol, biopower, and other bioenergy/bioproduct manufacturing facilities in rural American can boost rural economies and exports.

  9. 9. OBP Mission And Strategic Goals Mission: 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 bioproducts. The results will be economic development, energy supply options, and energy security. Strategic Goals: 1) Reduce dependence on foreign petroleum. 2) Create a new, domestic bioindustry.Unlike a Dept of defense program we are not procuring a product or capability for the federal governments sole use.Instead we are trying to interest commercial industry to invest in and commercialize technologies for new and existing markets.We have a strategy for this enabling position. In this case the government need to understand the drivers for industry, understand how they make fundingdecisions, and present the opportunity in the language they understand. Our pathways, milestones, and decision points are based on sustainability, economics,and return on investment.

New Domestic Bioindustry PRODUCTS Fuels: – Ethanol – Renewable Diesel –Renewable Gasoline – Hydrogen Power: – Electricity – Heat (co-generation) Chemicals – Plastics Biomass Conversion – Solvents – Chemical Intermediates Feedstock Processes – Phenolics – Adhesives – Furfural – Trees – Fatty acids - Enzymatic Fermentation – Acetic Acid – Grasses - Gas/liquid Fermentation – Carbon black – Agricultural Crops - Acid Hydrolysis/Fermentation – Paints – Agricultural Residues - Gasification – Dyes, Pigments, and Ink – Forest Residues - Pyrolysis – Detergents – Animal Wastes – Etc. - Combustion – Municipal Solid Waste - Co-firing Food and FeedReplaced corn (which is ok to) with stover and oil refinery with an ethanol plant. Biorefineries could potentially use complex processing strategies to efficiently produce a diverse and flexible mixof conventional products, fuels, electricity, heat, chemicals, and material products from multiple biomass feedstocks. DOE is working to evaluate and develop the biorefinery concept into realworld models. Biorefineries in a simple form are present today in some agricultural and forest products facilities. These systems can be improved through better utilization of waste products andby applying the lessons learned from existing facilities to other comparable situations. These facilities both convert wastes to fuel material, but also upgrade fuel materials to product rawmaterials. These industries also produce by-products, which are commonly under-utilized or treated as waste. Finding higher value uses of these products as fuel and improving the processingefficiency of existing facilities is a primary goal of the BioInitiative.Cargill Dow is constructing a biorefinery to produce PLA from corn stover. The facility was dedicated earlier this month (April 2002) in Blair, NE. The facility will produce more than 300million pounds (140,000 metric tons) of PLA annually and employ up to 100 workers. The plant will requires 40,000 bushels of locally grown corn a day to meet global production demands.In 2000, Cargill Dow Polymers received $2.2 million under the BioInititative for its $4.6 million project “Bioenergy for Polylactic Acid, Ethanol, and Power”.•Development of a process technology for the fermentation of corn fiber and corn stover to lactic acid for conversion to polylactic acid (PLA); ethanol; and other products.•PLA has promising applications in food packaging; disposable products; and fibers for clothing, carpeting, and other applications. Future applications could include injection blow moldedbottles, foams, emulsions, and chemical intermediaries.•The versatility and anticipated price and performance of PLA will enable it to displace a significant volume of fossil-fuel-based polymers in the future. Projections include •Sales volume of 8 billion lbs/year by 2020 (Currently U.S. sales volume for plastics is about 70 billion lbs/year) •Reduction of 10 million tons of CO2 emissions by 2020 (due to displacement of fossil-fuel based polymers).•Ultimately, other sugar sources, such as residues from wheat and sugar beet production, will be used by Cargill Dow technology.

  23. 23. Systems Analysis Estimating Competitive Advantage and Environmental Characteristics of Technologies and SystemsConceptual process engineering design and techno-economic analysis is used extensively in the Program to carry out the detailed technical andfinancial assessments that are integral parts of the Stage Gate process. We practice a graded approach to these assessments meaning that asthe projects move along the development pathway, the assessments become more robust and hopefully, more accurate. The Program hasdeveloped a series of detailed process models and assessment tools for the main process concepts under development. These tools are usedwhere appropriate. However, when new ideas or process concepts are being considered, these models and tools must be developed. Theinformation below describes the level of robustness appropriate for the assessments at each gate in the process.
