2. Biodiesel Monoalkyl Esters Created via base- catalyzed transesterification of triglycerides from biolipids Capable of replacing petro diesel in diesel engines

3. Advantages over Petro Diesel Renewable Biodegradable/Nontoxic No Sulfur/High Lubricity Carbon Neutral Lower Flash Point Reduced Emissions

4. Biodiesel Sources Edible Plant Oil (Soybean, Rapeseed) Inedible Plant Oil (Jatropha, Jojoba) Animal Fat (Tallow, Lard) Algal Oil Fungal Oil

5. Algal Oil Not a major food source Non-arable land growth High oil content Wastewater compatible Fast growth Reduce Plant Emissions

6. Biodiesel from Algae Algae selection Oil Content Growth Rate Growth Vessel (Photobioreactor) Nutrients Temp/pH/Sunlight

7. Biodiesel from Algae cont. Separation Centrifugation Flocculation Filtration Extraction Expeller Press Solvent Extraction Ultrasonic Lysing

8. Biodiesel from Algae cont. Transesterification High Viscosity Oil catalyst, heat, excess alcohol Products: biodiesel, catalyst, alcohol, glycerol

9. Viability Costs Still experimental Additive Fuel
