Transcript

  • 1. Bob Falco, PhD Pete Sheehey, PhD Institute for Energy ResourcefulnessPresented to the LAC Transportation Committee 12 July 2012
  • 2.  The EPA has researched the use of high percentages of alcohol in engines  Scientifically prescribed path to easy introduction of methanol  MIT Engine Lab and Lotus Engineering  The path utilizes the availability of current Flex Fueled Vehicles (FFV)  There are over 11,000,000 FFV in the US  All new vehicles purchased by Los Alamos County are Flex Fuel Capable7/12/12 Institute for Energy Resourcefulness 2
  • 3.  High cost of vehicle conversion High cost of pumping stations High cost of maintenance Lower efficiency/power of vehicles No easy transition path Locked into a single technology and fuel at a time of rapidly developing fuels technology
  • 4. 40%G 10%E 50%M Lotus Engineering Research 7/12/12 4 Institute for Energy Resourcefulness
  • 5. G=$3.11 % methano l G= $3.73 Lotus Engineering
  • 6. • Can be made from natural gas (100-120 yrs)• No competition with food• No water use issues• Cheaper to make than gasoline Additional advantages• Engines can be optimized to run with higher efficiency than diesels• Lower CO2, • CO2 neutral if bio methanol • CO2 negative if solar energy is used• Methanol can be made renewablyInstitute for Energy Resourcefulness 6 7/12/12
  • 7.  Reduce engine system costs (engine plus exhaust treatment) by $10,000 - $15,000.  The engines cost less (diesels are more expensive)  No need for either the Diesel Particulate Filter or the Urea Filter (NOx) Reduced maintenance Fuel costs less Better mileage – up to 5% better fuel economy Institute for Energy Resourcefulness 7/12/12 9
  • 8. EIA Nov 08 100 -120 years supply Institute for Energy Resourcefulness
  • 9. COWS------ > BIOGAS----- > GASIFIER -- > METHANOL---- > VEHICLES Landfill NET EFFICIENCY = .70*.85 = 59.5%Institute for Energy Resourcefulness 11 5/30/12
  • 10. COWS---- > BIOGAS--- > SOLAR FURNACE -- > METHANOL--- > VEHICLES Landfill Maximum theoretical efficiency = 1.3*.85 = 1.10% 12 5/30/12Institute for Energy Resourcefulness
  • 11. A Way Forward for Economical Environmentally Responsible Transportation Policy in Los Alamos County• Do a test on an older E-85 vehicle. Buy methanol on open market and establish the use of GEM mixtures.• If successful run a small test fleet • Mix locally at airport pumping station?• Expand fleet using GEM mixture • Contract for a long term methanol price (see supplemental slides) The above can be done with existing vehicles• Buy all new vehicles with capability of 100% methanol usage • Passage of the “Open Fuels Act” will mandate this• Renewable methanol from LA landfill gas emissions• Use classical gasifiers to make methanol from landfill gas• In the future, add solar gasifiers to make additional methanol • Gain 30% in available energy • Utilize all of the CO2 emitted• Apply for Federal Production Tax Credit Institute for Energy Resourcefulness 7/12/12 13
  • 12.  CNG $2.54*200,000/5 = $101,600 LNG $1.70 * 200,000/5 = $68,000 Diesel $3.91 *200000/5 = $156,400 Methanol $2.64*200000/5 = $105,600 $75,000 cost increment to convert a full sized bus to CNG --------------------------------- Over 200,000 miles --  Converting to Methanol Saves:  Diesel – Methanol = $156,400 - $105,600 = $50,800  Converting to LNG Saves:  Diesel – (LNG + $75,000) = $156,400 – ($68,000 + $75,000) = $156,400 – 143,000 = $13,400 ----------------------------  Additional cost of CNG fuel pumps $300,000-$500,000  Additional cost of methanol dispenser/tank from $25,000 to $50,000 Institute for Energy Resourcefulness 7/12/12 14
  • 13.  CNG $2.54*200,000/5 = $101,600 LNG $1.70 * 200,000/5 = $68,000 Diesel $3.91 *200000/5 = $156,400 Methanol $2.64*200000/5 = $105,600 $75,000 cost increment to convert a full sized bus to CNG --------------------------------- Over 200,000 miles --  Converting to Methanol Saves:  Diesel – Methanol = $156,400 - $105,600 = $50,800  Converting to LNG Saves:  Diesel – (LNG + $75,000) = $156,400 – ($68,000 + $75,000) = $156,400 – 143,000 = $13,400 ----------------------------  Additional cost of CNG fuel pumps $300,000-$500,000  Additional cost of methanol dispenser/tank from $25,000 to $50,000 Institute for Energy Resourcefulness 7/12/12 15
  • 14.  Transportation costs can be reduced using existing vehicles – hundreds of dollars vs. tens of thousands per vehicle. Future vehicles can be less expensive to purchase and operate if run on GEM mixtures. Methanol can be contracted from NM farms or purchased cheaply on long term contract. Maintenance is traditional, not the complication of CNG Flexibility in fueling  Cellulosic ethanol production breakthrough can immediately be accommodated  Butanol production breakthrough can be accommodated  Flex Fueled hybrids are a natural extension for increased mileage Institute for Energy Resourcefulness 7/12/12 16

  • 18. Safety GASOLINE METHANOL• In the California test (15 years), with over 200 million miles of methanoldriving, there was not a single case of accidental methanol poisoning.• For M100 a 90% reduction in fuel related automotive fires is projected.

  • 23. EPA Brake Thermal Efficiency Comparisonengine fueled on 100% same engine run in its methanol native diesel mode (1.9L VWin spark ignition mode TDI diesel) 39% 42%Typical 1.9L gasoline engine has 22-25% BTE Institute for Energy Resourcefulness 26 5/30/12
  • 24. Ethanol/Methanol can give diesel engine efficiencieswithout the need for high pressure injection systems andeither DPF or Urea NOx reducing exhaust treatment. Test in a VW TDI 1.9 L diesel engine which was converted to spark ignition for the ethanol tests. The compression ratio was 19.5 to 1.
  • 25. “Combined with an optimized conventional drivetrain, theefficiency gain shown in the previous slide for E30 shouldyield an estimated 10% - 12% gain in fuel economy. Thus itmore than compensates for the approximately 8% loss in fuelenergy density of E30 vs. straight gasoline.” EPA
  • 26. Even Ethanol/Gasoline mixtures as low asE30 can give engine efficiencies thatapproach those of a diesel.These SI engine efficiencies are 25% greaterthan attainable in current gasoline only fueled engines
