  1. ODOT Bio-diesel Experience Overview WSHEMA Conference Bend, Oregon August 24th, 2010 Gregory Brown & Lori Webb

  2. Starting Point • Started using B-20 in 2003 • 2007, Governor mandate – 25% B-20 usage. • 2009 B-02  B-05 soon.

  3. What is Biodiesel? • Organic Based Oil • Derived From Vegetable Feedstock • Refined to Consolidate Methyl Esters

  4. Benefits & Problems Pros Natural Olefins Sustainable Fuel Source Cleaner Engine Emissions Reduced Global CO2 Effect Cons Higher Cloud Point Solvent Effect Less Power Cost

  5. Tank Contamination Conditions promoting bio-growth: Water accumulation in tank Open vent or partially filled tank Warm weather Food Source

  6. Fuel Polisher • 24 hour/7 day/week fuel circulation. • Debris filtration • Water Separation • Heater

  7. Warranty Most engine manufacturers warranty B-fuels, check ratio! Use oil analysis program to prove compatibility Ensure ASTM certified fuels are being used.

  8. People Science Reliability? ASTM Fuel Specifications. Splash mixing for better consistency. Oil Sampling for engine monitoring. Fuel Filter monitoring and replacement.

  9. Obstacles • Crew Uncertainty • Tank Maintenance • Availability • Cold Weather Performance

  10. Cost More expensive due to reduced economies of scale in production. Increase in food costs will increase fuel costs. Higher concentration blends will cost more.

  11. Solutions • Crew Education and Training • Agency Consensus on Fuel Use • Vendor Consultation

  12. Future Developments • Develop a Fuel Tank Maintenance Program. • Centralize Tank Management Through Fleet. • Implement Fuel Polishing Technology.

  13. Discussion Tell us what you think!
