3 3 | Bioenergy Technologies Office The Challenge and The Opportunity The Challenge More than 13 million barrels of petroleum based fuels are required daily for the U.S. transportation sector – 8.5 million barrels of gasoline for the motor vehicles alone. 1 67% of U.S. petroleum consumption is in the transportation sector ($350 billion) 2 7% of U.S. petroleum consumption is for chemicals and products sector ($255 billion) 2 – Relative value is much higher for chemicals and products. The Opportunity Biomass is the leading renewable resource that can provide drop-in fuel replacements utilizing existing infrastructure for light and heavy duty vehicles and air transportation 1 More than 1 billion tons of sustainable biomass could be produced in the U.S. which can provide fuel for vehicles and aviation, make chemicals, and produce power for the grid. 30% of U.S. petroleum usage could be displaced using terrestrial biomass by – This does NOT take into account algae which could provide up to 5 billion gallons/year High value chemicals and products from biomass can stimulate biofuels production. 1 Energy Information Administration, 2012 Energy Review, U.S. Department of Energy, Frost, John, Redefining Chemical Manufacture, Industrial Biotechnology, Spring 2005 (numbers are assumed to be annual figures for 2004) 3 Update to the Billion-ton Study, U.S. Department of Energy, 2011

4 4 | Bioenergy Technologies Office Develop and transform our renewable biomass resources into commercially viable, high-performance biofuels, bioproducts, and biopower through targeted research, development, demonstration, and deployment supported through public and private partnerships. Develop commercially viable biomass utilization technologies to enable the sustainable, nationwide production of biofuels that are compatible with today’s transportation infrastructure and can displace a share of petroleum-derived fuels to reduce U.S. dependence on oil and encourage the creation of a new domestic bioenergy industry. Mission Strategic Goal Mission and Strategic Goal By 2017, validate a $3/GGE hydrocarbon biofuel (with ≥50% reduction in GHG emissions relative to petroleum-derived fuel) for a mature modeled price for at least one hydrocarbon technology pathway at pilot scale. By 2022, validate hydrocarbon biofuels production at >1 ton/day from at least two additional technology pathways at pilot or demonstration scale. By 2017, validate a $3/GGE hydrocarbon biofuel (with ≥50% reduction in GHG emissions relative to petroleum-derived fuel) for a mature modeled price for at least one hydrocarbon technology pathway at pilot scale. By 2022, validate hydrocarbon biofuels production at >1 ton/day from at least two additional technology pathways at pilot or demonstration scale. Performance Goals

6 6 | Bioenergy Technologies Office Significant Commercialization Challenges Photos Courtesy Sapphire Energy Challenges Affordable and scalable algal biomass production: Current commercial technologies are designed for production of high-value products rather than high-yielding commodity-scale products. Current facilities use high-cost liners, nutrients, and predator controls. Siting and sustainability of resources: Nutrient recycle has limited use. CO 2 delivery requirements limit siting decisions. Cultivation currently requires significant water resources. Harvesting and preprocessing technologies are not energy efficient. Competition for CO 2 has significantly increased its cost. There are two overarching challenges to reaching program costs and performance goals: (1)Reducing costs of production. (2)Ensuring sustainability and availability of resources.

7 7 | Bioenergy Technologies Office Algae Program Goals and Objectives Courtesy Sapphire Energy, LLC Program Performance Goal Develop and demonstrate technologies that make sustainable algal biofuel intermediate feedstocks that perform reliably in conversion processes to yield renewable diesel, jet, and gasoline in support of the BETO’s $3/gge biofuel goal in Photo Courtesy of ATP3 Photo Courtesy of Texas A&M Approach Set aggressive productivity targets (1,500 gallons of biofuel intermediate per acre annual average by 2014 – achieved; 2,500 gallons by 2020; and 5,000 gallons by 2022). Use techno-economic, life-cycle analysis, and other validated models as tools to direct research and development; evaluate performance towards goals; and down-select pathways, processes, and performers as appropriate. Leverage a strong foundation of ecology, advanced biology, and physiology to improve yield and productivity. Incorporate engineering solutions to reduce operating costs.

8 8 | Bioenergy Technologies Office Program Approach: Integrated Research and Development To achieve program goals, the Algae Program funds research and development across technology readiness levels (TRL 2-6) within a broad portfolio of disciplines across the production and logistics chain, while interfacing with the Conversion, and Demonstration and Market Transformation Programs.

13 13 | Bioenergy Technologies Office For more information visit: The Demonstration and Deployment Program manages a diverse portfolio of projects focused on the scale-up of biofuel production technologies from pilot- to demonstration- to pioneer- scale. Of the 33 biorefineries that have received funding through BETO, 3 have been completed, 5 are in close-out, and 5 have been either terminated or withdrawn. The remaining 20 biorefineries are considered active and utilize a broad spectrum of feedstocks and conversion techniques. There are 4 algae projects: Sapphire, Solazyme, Algenol, and BioProcess Algae. Demonstration and Market Transformation Portfolio – Overview Map of BETO-funded Projects Note: Bioprocess is the only I-Pilot Project that appears on this map. Sapphire Solazyme Algenol BioProcess

14 14 | Bioenergy Technologies Office Demonstration Portfolio Algenol Algenol’s technology utilizes blue-green algae to directly produce ethanol; hydrothermal liquefaction can also be used to produce hydrocarbon fuels from wet algae. Marine blue-green algae is also cultivated in vertical photobioreactors (PBRs) in salt water. Recent progress includes continuous operation for 6 months of a 40 block unit (40 PBRs); and continuous operation for an extended period of a 4,000 block unit (4,000 PBRs in 1 acre). Goal for full capacity is 100,000 gallons/year; the project is scheduled for completion in December Solazyme Solazyme’s technology utilizes sucrose and cellulosic-derived sugars fed into a heterotrophic algae system to produce jet fuel and diesel. Dark fermentation is used to accelerate the microalgae’s oil production. Solazyme works with Chevron, UOP Honeywell, and other industry refining partners to produce renewable diesel for vehicles and ships, and renewable jet fuel for both military and commercial application testing. Performance tests utilizing cellulosic-derived sugars was completed in January 2014; the completed facility is expected to have a capacity of 300,000 gallons/year.

15 15 | Bioenergy Technologies Office Demonstration Portfolio Sapphire Energy Sapphire’s algae is cultivated in open raceway ponds; “green crude” is converted into jet fuel and diesel. Sapphire has completed continuous operation of at least 22 acres of ponds exceeding 15 months. Sapphire repaid its USDA Loan Guarantee ahead of schedule, and has signed a joint development agreement with Phillips 66, and partnered with the Linde Group and Tesoro Refining. The completed facility is expected to have a biofuel capacity of 1,000,000 gallons/year. BioProcess Algae BioProcess produces kilogram quantities of heterotrophic lipids using a mixo-trophic algal system co-located at an ethanol plant ready for refining into on-spec military fuels (F- 76, JP-5 and JP-8). The project comprises 9 greenhouses, on 14 acres, and is designed to process 2.5 tons per day. This project is a new start, the project was selected in FY13, and validation is expected in FY14.

16 16 | Bioenergy Technologies Office Recent BETO Award Announcements Algal Biofuels Research Following a 2013 FOA, DOE announced $3.5M in additional funding to support the Department’s goal of producing 2,500 gallons of algal biofuel feedstock per acre per year by 2018, an important milestone toward reducing the cost of algal biofuels to cost- competitive levels of 5,000 gallons per acre per year by Cellana, LLC, in Kailua-Kona, Hawaii, was selected to receive $3.5M to develop a fully integrated, high-yield algae feedstock production system by integrating the most advanced strain improvement, cultivation, and processing technologies into their operations at Kona Demonstration Facility. Carbon, Hydrogen and Separation Efficiencies Following a 2013 FOA, DOE announced $6.3M in additional funding to support lowering production costs by maximizing the renewable carbon and hydrogen from biomass that can be converted to fuels and improving the separation processes in bio-oil production to remove non-fuel components. One of these awards is: SRI International of Menlo Park, California will receive $3.2M to produce a bio-crude oil from algal biomass that will maximize the amount of renewable carbon recovered for use in fuel and reduce the nitrogen content of the product in order to meet fuel quality standards.

17 17 | Bioenergy Technologies Office New Funding Opportunity GOAL: The Targeted Algal Biofuels and Bioproducts (TABB) FOA seeks to reduce the cost of algal biofuels from $7 per gallon – the current projected state of technology for 2019 without this FOA – to less than $5 per gallon algal biofuel by 2019, through non-integrated bench and process development scale technology improvements.Targeted Algal Biofuels and Bioproducts (TABB) FOA CHALLENGES: Algae Program funded work has highlighted barriers to broad commercialization must be overcome with both higher yields in scalable cultivation systems and higher value of the algal biomass. FOA OBJECTIVES: The FOA selection process will identify projects in two topic areas: 1.Multi-disciplinary consortia that bring together upstream and downstream expertise to develop algae cultures that produce valuable bioproduct precursors, alongside fuel components, to increase the overall value of the biomass; 2.Single investigator or small team technology development projects focused on developing crop protection and CO 2 utilization technologies to increase yields. ADDITION TO PORTFOLIO: This FOA builds on the existing advances towards productivity goals, but is unique from all prior efforts in that the FOA outcome will be a finished fuel rather than a biofuel intermediate. This FOA is the first from the Algae Program to explicitly fund bioproducts R&D in addition to biofuels.

20 20 | Bioenergy Technologies Office R&D Breakthroughs NAABB has screened over 1,500 strains and identified 30 promising algae that show marked improvement over baseline production. High-yield strains have been shared with partners for testing in their outdoor cultivation facilities. A scanning electron microscope image of the diatom Thalassiosira pseudonana Researchers at the Scripps Institute of Oceanography made a significant breakthrough in the metabolic engineering of algae to improve yield of lipids (the energy-storing fat molecules that can be used in biofuel production) without inhibiting growth. Development of “Rainbow Algae,” the result of stacking multiple traits localized throughout genome with robust expression and targeted protein localization. This has resulted in high-impact demonstration of genetic engineering breakthroughs to allow for the insertion and expression of genes as well as the tagging of proteins throughout the algal cell.

27 27 | Bioenergy Technologies Office In July 2011, the Secretaries of Agriculture, Energy, and Navy signed a Memorandum of Understanding to commit $510 M ($170 M from each agency) to produce hydrocarbon jet and diesel biofuels in the near term. This initiative sought to achieve: Multiple, commercial-scale integrated biorefineries Cost-competitive biofuel with conventional petroleum (without subsidies). Domestically produced fuels from non-food feedstocks. Drop-in, fully compatible, MILSPEC fuels (F-76, JP-5, JP8). Help meet the Navy’s demand for 1.26 billion gallons of fuel per year. Contribute to the Navy’s goal of launching the “Great Green Fleet” in Demonstration of the production and use of more than 100 million gallons per year will dramatically reduce risk for drop-in biofuels production and adoption. On September 19 th, three projects were selected for construction and commissioning: Defense Production Act (DPA) Initiative CompanyLocationFeedstockConversion PathwayCapacity (MMgpy) Gulf CoastFats, Oils, and Greases Hydroprocessed Esters and Fatty Acids (HEFA) 82.0 McCarran, NVMunicipal Solid Waste Gasification – Fischer Tröpsch (FT) 10.0 Lakeview, ORWoody Biomass Gasification – Fischer Tröpsch (FT) 12.0

28 28 | Bioenergy Technologies Office Aviation Biofuels: Accomplishments/Milestones The Commercial Alternative Aviation Fuels Initiative (CAAFI) has set a goal of 1 billion gallons per year of alternative jet fuel by 2018 (the commercial aviation market currently 20 billion gallons per year), and DOE is playing an active role by providing technical expertise in various high-level aviation activities, including: Becoming the latest partner agency for Farm to Fly 2.0, joining the aviation sector as well as Department of Agriculture (USDA) and Federal Aviation Administration (FAA) in an agreement to enable commercially viable and sustainable jet fuels in the U.S. Serving on CAAFI Steering Group and as a co-host with the FAA for the Aviation Biofuels Techno-Economic Analysis Workshop, November Working with FAA to develop a National Alternative Jet Fuels Strategy Roadmap (December 2014). Supporting FAA’s newly established Center of Excellence in alternative jet fuels led by Washington State University/MIT, and supported by National Renewable Energy Laboratory and Pacific Northwest National Laboratory. Increasing technical work at National Laboratories to enable achievement of alternative jet fuel goals.

29 29 | Bioenergy Technologies Office Significant progress has been made as a result of DOE investment over the past 3 years in advancing the baseline described in the BETO Multi-Year Program Plan Innovative work across the value chain is showing promise in reducing costs: Increased productivity achieved through new strains, strain engineering, breeding, and application of polycultures Advances in sustained outdoor cultivation through crop protection, nutrient management, and pond design and managements Process engineering leading to highly efficient biomass to biofuel intermediate yields in the 60-70% range. (Demonstrated by Bioprocess Algae and the National Alliance of Advanced Biofuels and Bioproducts Consortium) Higher yields lead to greater than 50% reductions in land and water requirements in order to achieve 5 billion gallons per year production scenario.

Technical, construction, operational and financial/market risks. Key Challenges BiomassPretreatmentConversionProduct Reliable supply Consistent quality Affordable delivery Biomass feeding, sizing and moisture Solids handling Construction materials Products Yields Construction materials Catalysts Fermentation organisms Separations Catalytic upgrading Recycle loops

33 33 | Bioenergy Technologies Office A 42-gallon (U.S.) barrel of crude oil yields about 45 gallons of petroleum products. Greater focus is needed on RD&D for a range of technologies to displace the entire barrel of petroleum crude. U.S. spends about $1 Billion each day on crude oil imports.* Only about 40% of a barrel of crude oil is used to produce petroleum gasoline. Cellulosic ethanol can only displace the portion of the barrel that is made into gasoline. Reducing our dependence on oil also requires replacing diesel, jet fuel, heavy distillates, and a range of other chemicals and products that are currently derived from crude oil. * American Petroleum Institute Replacing the Whole Barrel
