This is a presentation I gave to a Sertoma Club in Knoxville in July this year. It covers a lot, starting with our coalition and what we do, then going through basics and background on oil and oil systems, to actions taking place in East Tennessee today to help us move away from oil alone in the transportation sector.

  • Car pool, ride mass transit (school bus). Get cars with better fuel efficiency or just drive less—walk or ride your bike.
  • Some Experts think it may have already happened. The most optimistic prediction is in 2030—that’s only 22 years from now! The point is that this is your lifetime we are talking about. You could live to see life after the oil age. Next. Slide.
  • We are trying to get to the donuts of sugar. We have to break through the lignin and split apart the cellulose and hemicellulose chains to get to them. Once we have the little donuts of sugar we can ferment and distill them, just like with regular ethanol production, and turn them into ethanol!
  • Well suited to the Southeast Currently, ~6-8 tons/acre in TN Potential for 12+ tons/acre Warm season, native, perennial grass Tolerates poor soils, flooding, drought Highly resistant to many pests and plant diseases Low use of chemicals or fertilizers 1-2 year establishment Weed control critical in establishment Initial production practices similar to hay Working toward next generation harvest, storage, management improvements UT has long history of switchgrass production and market research
  • Switchgrass starts with a tiny little seed (smaller than a dime), but it grows into a very large grass, 6-10 ft tall. Also, switchgrass is wildlife friendly, providing an environment for animals such as deer and birds. In this last picture, we see harvested switchgrass that will be turned into a fuel as well as maturing switchgrass growing in the background. Overall, this process is much more earth friendly than corn ethanol—which is why there is a limit on corn ethanol in the nation’s alternative fuel plan. Cellulosic will mostly fill the rest of the requirement.
  • Collaboration with DuPont Dansico Cellulosic Ethanol, LLC Vonore location: Niles Ferry Industrial Park, Monroe County, 32 acres Optimized as precursor to commercial demonstration (~25 MGY) Long-term operation as an RD&D facility Genera developing switchgrass pelletization and utilization demonstrations Owned by Genera Energy, operated by DDCE Expect completion, ethanol production by end of 2009 Multiple feedstocks: first cob then switchgrass Flexibility in process design, operation 250 KGY capacity in pilot, separate process development unit (PDU)
  • 723 acres planted in 2008 2150 to be planted in 2009 3 year acreage-based agreements/contracts with farmers $450/acre per year plus seed and technical assistance

    • 3. We Are All Partners in American Change
      • “ I believe Sertoma is awake to the fact that our future is decided now, not later.  The future of Sertoma is the results of choices we make in these days.”
      • - Woody Hudson
    • 4. Who is the ETCFC?
      • Designated member of U.S. DOE Clean Cities Program
      • 7-yr old nonprofit in East TN
      • Focused on transp. sector change: diversify and use less !
      • Meetings; direct fleet & fuel supplier assistance; workshops; presentations to the commercial/industrial/ gov’t community and to schools; multiple newsletters
      • Who are our partners? Fuel suppliers, industry, cities and counties, utilities, universities, fuel producers, fed. agencies, other non- profits, state agencies, car companies, auto manufacturers
    • 5. Presenting to the Tennessee Trucking Association
    • 6. The Clean Cities map - 2008
    • 7. Success Stories – Example #1: East Tennessee Biodiesel Use
      • From humble beginnings in 2004, biodiesel use expanded fairly rapidly through 2007, with major peak in 2006 (pricing)
      • In 2006, our total life-cycle CO2 emissions reductions in East TN from fleets using biodiesel blends was a minimum of 6,400 tons CO2
    • 8. Success Story #2: Community Champion: Fleet Leader - Eastman
      • Started working with Eastman in 2003 to get them as regional leader using biodiesel; they started in 2004
      • BAE Systems followed soon thereafter, and since 2004 another 4 larger-sized fleets have started using biodiesel
      • Two farmers coops became suppliers and a couple of fuel suppliers have started offering the blend
      • We are in discussions with another ~10 fleets in the area about getting started
      (200 heavy-duty vehicles, 150 pieces of equipment, and 6 locomotives)
    • 9. Success Story #3: K-12 School Presentations
      • Presentations focus on relaying the basics and importance of alt fuels and fuel economy to the students
      • ’ 06-’07 = 700+ students reached
      • ’ 07-’08 = 1,700+ students reached
      • ’ 08-’09 = 3,600+ students reached
      • “ 1st Graders for Clean Fuels ” program works on all five of the senses through an interactive presentation
      • “ Clean Fuels Jeopardy!” a hit! Patricia Weaver started Fall ’08; been used ever since with variety of ages and classes
    • 10. Success Stories – Example #4: ET Cities & Towns – Leaders for Biodiesel (and smaller that have started biodiesel projects)
    • 11. Current ET Public Biodiesel/E85 Stations Biodiesel: 20 -- B99-1, B20-11, B5-8 E85: 12 (at least 3 more to open this year!)
    • 12. Question: In 1945, we were 0% dependent on foreign countries for oil; now we are 60+% dependent. ~ 60 years = 0 -> 60% reliance on others for oil ~ During WWII, when this country joined the Allies in the war effort, all the allies began using their oil for fuel. Which country is this ?
    • 13. Domestically Produced Alternative Fuels
      • Biodiesel-95%
      • Propane-95%
      • Electricity-100%
      • Ethanol-95%
      • Natural gas-90%
      Gasoline + Diesel = 40% vs.
    • 14. Alt Fuels Cannot Do It Alone! Fuel Efficiency Alternative Fuels Conservation Cleaner Air & Oil Independence Reduce Eliminate Replace
    • 15. The Carbon Basics
      • CO2 is the transportation sector’s primary global warming gas; thus, total GHG emissions will be slightly greater than the CO2 emissions totals
      • CO2 emissions are proportional to fuel consumption: 19.4 pounds CO2/gal gas ; 22.2 pounds CO2/gal diesel
      • CO2 emissions are inversely proportional to fuel economy
        • Each 1% decrease in fuel consumption results in a corresponding 1% decrease in CO2 emissions
      • Therefore, the #1 tool in your CO2-reducing toolkit is reducing your total petroleum consumption ; find regular or innovative ways to do so!
    • 16. The Life-cycle Carbon Numbers : Petro-fuels and Alternatives

      • 14 public E85 stations open now; ~3 more on their way!
      • Over 60% of all public stations in ET now have E10
      • Tennessee Ethanol Plants
      • 1 open today = Tate & Lyle – Loudon County (75 MGY)
      • Just opened = EGP – Obion County (NW TN; 100 MGY)
      • Opening in 2009 = Genera Energy – Monroe County (small)
      • Pros
      • E10 can run in ANY gasoline vehicle (E20, E30, E40?)
      • E85 in flex-fuel vehicles; can vary the blend!
      • Cons
      • For E85, more power (octane rating of 105), but reduced fuel economy of around 20-25% (just need fuel to cost about 20% less)
      Ethanol – Summary
    • 33.
      • 20 public stations; about 40 ET fleets using biodiesel today
      • Production Plants in East Tennessee
      • Suns-Oil, LCC – southeastern TN
      • Nu-Energie, LLC – closed
      • Pros
      • Is the only alt fuel that can yield increased economy and power
      • No new vehicles or infra. Required; Fill-n-go option at ≤ B20
      • Renewable; less smoke & smell; biodegradable & nontoxic
      • Helps equipment last longer; less wear and tear
      • Cons
      • Possible fuel filter changes; all biodiesel gels faster than diesel

      • Solix, Solazyme, others are current leaders
      • Increasing oil yield per acre is one key to their growth
      • CO2 uptake from power plants another benefit
