Algenol Biofuels is developing DIRECT TO ETHANOLTM technology
• Science driven: using biotechnology to produce fuel and utilize CO2 emissions • 100 employees and consultants (40 Ph.D.’s) • Biological laboratoriesin Baltimore, Maryland and Germany • The Algenol Biofuels Cyano Collection - nearly 10,000 algae strains • Zero-discharge R&D aquaculture facility in Palm Beach County, Florida • Pilot demonstration plant with Dow Chemical – construction start in 2010 • Company headquarters in Naples, Florida

Harnessing the Sun to Fuel the WorldTM ALGENOL’S PROCESS IS UNIQUE
• ALGENOL inputs: • Algae •Sunlight • CO2 (from the air or industrial sources) • Saltwater • Marginal or Desert Land ALGENOL does NOT use: • Farmland • Food Feedstocks • Fresh Water • Fossil Fuel Fertilizers

6000 gal/acre/yr; corn 400 5.5-to-1 energy balance 70-80% reduced CO2 footprint we make fresh water

•

we make natural compost or biodiesel

Direct to EthanolTM
Algenol links photosynthesis with the natural enzymes that convert sugars directly into ethanol. The ethanol diffuses out of the cell and evaporates rapidly. • All in each cell • All at the same time

U.S. has all the barren land needed and more . . .
Algae: 6,000-10,000 gal/acre

Algae has a much greater per acre production of ethanol, as compared to ethanol from corn or cellulose Algae requires 6% land coverage compared to corn

Cellulosic 870-890 gal/acre

No indirect landuse change Positive CO2 capture and no food displacement

Corn 340-420 gal/acre

Gallons of Fresh Water
Consumed Per Gallon Fuel
Source: National Renewable Energy Laboratory

Produced Per Gallon Fuel

• • • •

ALGENOL Ethanol = 1 gallon fresh water produced per gallon fuel
• (consumes 2gallons of seawater to make: 1 gallon ethanol, 1 gallon fresh water)

Gasoline = 2-2.5 gallons of fresh water consumed per gallon fuel Corn Ethanol = 3-4 gallons fresh water consumed per gallon fuel (EXCLUDING irrigation) Cellulosic Ethanol = 2-6 gallons fresh water consumed per gallon fuel (EXCLUDING irrigation)

Harnessing the Sun to Fuel the WorldTM
• Algae strain selection and enhancement• • Maintain and expand ALGENOL strain collection Develop site-specific strains for temperature, salinity, and other variables

ALGENOL’s Current Technology Initiatives

•

Photobioreactor (PBR) design and manufacturing
• • Commercial scale tested and deployed in 2009 at Florida R&D Facility Partnership with Dow Chemical for advanced materials

•

GasManagement for PBR Head Space
• • • • CO2 Capture and Delivery to the PBR O2 Separation Ethanol-water separation Partnership with Georgia Tech and CUT CO2 Technologies

•

Integrated Biorefinery Pilot (24 acre facility in Texas)
• • • Filed application for DOE funding jointly with Dow Chemical $25 million max grant – greater than $50 million project Awards announced November 09 - funding in2010

•

Life Cycle Analyses
• • First phase of fuel study essentially complete (Georgia Tech) Next phase will consider polyethylene as final product (Georgia Tech/Dow)

1.5 x 15 meter Photobioreactors Deployed at Florida R&D Facility in 2009
