Assertions for Alternative Fuels

• We dont need oil for cars light trucks
• We definitely dont need hydrogen!
• We dont need new car/engine designs
• We dont need new distribution systems
• Rapid (3-5 yrs) changeover of automobiles is
  possible!
• Shift has little cost to consumers, automakers,
  government

3
Not so Magic Answer Ethanol
Cheaper Today in Brazil!
4

• Initial fuel markets thru blending- reduced
  production risk
• Excess supply for kick start available from
  Brazil
• High oil prices accommodate startup costs of
  ethanol
• Breakeven at scale likely to be 35/barrel
• Carbon considerations will further improve
  economics
• 20 /yr increase of US ethanol production
  already in process
• Significant increase in farm profits feasible -
  better use for farm subsidies
• 4m US FFV vehicles, 4b gals ethanol supply,
  blending in place,.
• Many US car models available at same price (FFV
  or gasoline)

8
Flex Fuel Vehicles (FFV)

• Almost no incremental cost to produce low risk
• Confidence on fuel availability to consumers
• Easy switchover for automobile manufacturers
• 4 million FFV cars in the US today (to earn CAFE
  credits)
• Consumer choice use EITHER ethanol or gasoline
  (no risk)
• Fully compatible with Hybrid cars
• Brazil Proof new car sales from 4 FFV to
  70 in 3 years!
• Growth in ethanol use driven by low prices of
  ethanol
• Brazil 50b on oil imports savings

9
Interest Groups

• US Automakers less investment than hydrogen
  compatible with hybrids
• Agricultural Interests more income, less
  pressure on subsidies new opportunity for
  Cargill, ADM, farmers co-operatives,
• Environmental Groups faster lower risk to
  renewable future aligned with instead of against
  other interests
• Oil Majors equipped to build/own ethanol
  factories distribution lower geopolitical
  risk, financial wherewithal to own ethanol
  infrastruct. diversification
• Distribution (old New) no significant
  infrastructure change potential new distribution
  sources (e.g. Walmart)

10
Interest Groups Action Items

• US Automakers 100 flex-fuel new car
  requirement in exchange for some regulatory
  relief
• Agricultural Interests 100 flex-fuel new cars
  but no tax on imported ethanol transfer
  subsidies from row crops to energy crops
  (equivalent /acre)
• Environmental Groups tax-credit for cellulosic
  ethanol debt guarantees for new cellulosic
  ethanol technologies
• Oil Majors new business opportunity?
• Distribution (old New) assist ethanol third
  pump strategy promote ethanol distribution at
  destination sites (e.g. Walmart) fleets

11
Prioritized Action Items

• Require all cars to be Flex Fuel Vehicles (FFVs)
• Require E85 ethanol distribution at 30 of gas
  stations
• Assist debt financibility of first 5 plants with
  any new technology
• Allow fleets to import ethanol without tax burden
• Require automakers to promote ethanol usage to
  get CAFÉ credit
• Switch subsidies (same /acre) from existing to
  energy crops
• Allow carbon credits for cellulosic ethanol
• Fully fund current legislation reduce earmarks!
• Fund future demand with improved efficiency
  requirements!
• Establish early demand by creating strategic
  ethanol reserve

  less pesticide
• Less water pollution (nitrogen runoff)
• Dramatic reduction in CO2 , other reductions
• More biodiversity in switchgrass fields (vs.
  corn)
• Dramatically less topsoil loss compared to corn
  fields
• Significant potential for improvement of
  switchgrass crops
• High potential for co-production of animal feed
• Currently 50 of all agricultural land use
• Minimal extra land required for fuel production

and other varied crop possibilities exist the
worlds best agricultural lands were once

Bioenergy From Currently Managed Lands

• Expanded use of winter cover crops breeding of
  new (winter rotation) crops
• Harvest of agricultural residues, particularly in
  conjunction with multi-year crop rotations.
• Substitute crops that provide food/feed while
  also providing feedstocks for energy production.
• Breeding crops to increase co-production of
  cellulosic feedstocks. (soybeans 2-gt5 tons/acre)
• Changed cultivation practices for existing crops
  to increase recovery of cellulosic residues.
  (reduced till or no till rotation of corn with
  grasses etc)
• Increases in productivity of crops, making
  currently-managed lands avail for bioenergy.
• Changes in demand for exports ( or -).
• Pretreatment of cellulose-rich biomass to make
  calories more available to feedlot animals
• Increased hay productivity on underutilized
  pasture land.
• Increased hay production/harvest from CRP land.
• Recovered forest residues, potentially in
  relation to prevention of catostrophic fires.
• Dietary change

Three Important Sources
Stovers 250m tons Winter Crops 300m
tons Soybeans 350m tons

• Production of corn stover and stalks from other
  grains (wheats, oats) totals well over 250
  million dry tons. A combination of different crop
  rotations and agricultural practices (e.g.
  reduced tillage) would appear to have potential
  for a large fraction of these residues to be
  removed. For example, although complete removal
  of corn stover would result in a loss of about
  0.26 tons of soil carbon per year, cultivation of
  perennial crops (e.g. switchgrass, Miscanthus)
  adds soil carbon at a substantially higher rate.
  Thus, a rotation of switchgrass and corn might
  maintain or even increase soil fertility even
  with 100 stover removal. This, however, brings
  up questions about the length of time land might
  be grown in each crop, since switchgrass would
  benefit from longer times to distribute the cost
  of establishment while corn would benefit from
  short times to maintain productivity and decrease
  losses due to pests. It is likely that some
  crop other than switchgrass as it exists today
  would be best for incorporation into a relatively
  high frequency rotation with corn. Targets for
  crop development could be identified and their
  feasibility evaluated.
• Winter cover crops grown on 150 million acres
  (_at_2tons/acre) 300 million tons of cellulosic
  biomass.
• In recent years, U.S. soybean production has
  averaged about 1.2 tons of dry beans per acre
  annually. Given an average bean protein mass
  fraction of about 0.4, the annual protein
  productivity of soybean production is about 0.5
  tons protein per acre. Perennial grass (e.g.
  switchgrass) could likely achieve comparable
  protein productivity on land used to grow
  soybeans while producing lignocellulosic biomass
  at about a rate of about 7 dry tons per acre
  annually. The limited data available suggest
  that the quality of switchgrass protein is
  comparable to soy protein, and technology for
  protein extraction from leafy plants is rather
  well-established. The 74 million acres currently
  planted in soybeans in the U.S. could, in
  principle, produce the same amount of feed
  protein we obtain from this land now while also
  producing over 520 million tons of
  lignocellulosic biomass. Alternatively, if new
  soy varieties were developed with increased
  above-ground biomass (option 4, Table 1), this
  could provide on the order of 350 million tons of
  lignocellulosic biomass although soil carbon
  implications would have to be addressed.

Potential for Billion Tons of Biomass

• In the context of the time required to scale
  up to a large-scale biorefinery industry, an
  annual biomass supply of more than 1.3 billion
  dry tons can be accomplished with relatively
  modest changes in land use and agricultural and
  forestry practices

Ethanol Blends Emissions

• E6 (low ethanol blends)
• Low Nox in modern vehicles with oxygen sensors
  (higher in older vehicles)
• Increased RVP and increased VOCs (and hence
  ozone formation)
• Increased permeation emissions in older vehicles
• Reduced CO emissions (not enough to offset
  increased ozone via VOCs)
• but
• Reduced permeation emissions ( thicker hoses
  plastics) in newer vehicles
• California Low Emissions Vehicle II program
  reduces permeation and evaporative emissions
  (part of 2007 Federal Law)
• E85
• Low Evaporative emissions (Lower RVP)
• Expected Low Permeation emissions in FFVs
• Low Nox in modern vehicles with oxygen sensors

More Technology to Come.

• Changes that will have effects comparable to
  those of the Industrial Revolution and the
  computer-based revolution are now beginning. The
  next great era, a genomics revolution, is in an
  early phase.
• Thus far, the pharmacological potentials of
  genomics have been emphasized, but the greatest
  ultimate global impact of genomics will result
  from the manipulation of the DNA of plants.
• Ultimately, the world will obtain most of its
  food, fuel, fiber, chemical feedstocks, and some
  of its pharmaceuticals from genetically altered
  vegetation and trees."

Hydrogen vs. Ethanol Economics

• Raw Material Costs cost per Giga Joule (gj)
• Electricity _at_0.04/kwh 11.2/gj (Lower cost
  than natural gas)
• Biomass _at_40/ton 2.3/gj (with 70 conversion
  efficiency)
• Hydrogen from electricity costly vs. Ethanol from
  Biomass
• Hydrogen from Natural Gas no better than Natural
  Gas
• Cost multiplier on hydrogen distribution,
  delivery, storage
• Higher fuel cell efficiency compared to hybrids
  not enough!
• Hydrogen cars have fewer moving parts but more
  sensitive, less tested systems and capital cost
  disadvantage

Hydrogen vs. Ethanol

• Ethanol US automakers balance sheets
  ill-equipped for hydrogen switchover
• Ethanol No change in infrastructure in liquid
  fuels vs. gaseous fuels
• Ethanol Current engine manufacturing/maintenance
  infrastructure
• Ethanol switchover requires little capital
• Ethanol Agricultural Subsidies are leveraged for
  social good
• Ethanol Faster switchover- 3-5 years vs 15-25yrs
• Ethanol Low technology risk
• Ethanol Incremental introduction of new fuel
• Ethanol Early carbon emission reductions

54
Strategy Tactics

• Choice Oil imports or ethanol imports?
• GDP beyond food to food energy rural
  economy
• Add 5-50B to rural GDP
• Better use for subsidies through energy crops
• Rely on entrepreneurs to increase capacity
• Rely on biotechnology process technology to
  increase yields .
• Increased ethanol use mandates already in place
• 20 /yr production capacity increase plans
  already in process!
• Ethanol fuel cells possibly after ethanol
  distribution is place (if needed)

• Level of cleanliness too high for biofuels
  better than petroleum or 100 Pure
• Level of domestic supply expectations why a
  100 domestic supply initially when petruleum is
  imported?
• Agricultural standards too high far more
  rigorous debate on new crops than on traditional
  crops?
• Debate on subsidy on ethanol but not on the tax
  on cheapest worldwide ethanol supply (Brazilian)?

ETHANOL AND EMPLOYMENT
( IN THE PRODUCTION OF THE VEHICLE AND OF FUEL)
Considering that an ethanol driven vehicle
consumes, on average, 2.600 litres of ethanol per
year ( one million litres of ethanol, per year,
generates 38 direct jobs )for gasoline, spends
20 less fuel ( one million litres of gasoline,
per year, generates 0,6 direct jobs) C
gasoline contains 25 ethanol.

Vehicle Modifications
Carburetor The material of the carburetor body or
carburetor cover cannot be aluminum or exposed
Zamak if it is, must be substituted, protect
with surface treatment or anodize Any component
in polyamide 6.6 (Nylon) that has contact with
the fuel must be substituted by other material or
protected The material of buoy, nozzle, metering
jet, floating axle, seals, gaskets and o-rings
must be appropriated.
Fuel Tank If the vehicle fuel tank is metallic,
the internal surface of tank must be protected
(coated) Any component in polyamide 6.6 (Nylon)
that has contact with the fuel must be
substituted by other material or
protected. Higher fuel tank capacity, due to the
higher fuel consumption.
Engine The engine compression ratio should be
higher Camshaft with new cam profile and new
phase New surface material of valves (intake and
exhaust) and valve seats.
Intake Manifold With new profile and less
internal rugosity, to increase the air flow Must
provide higher intake air temperature.
Catalytic Converter It is possible to change the
kind and amount of noble metal present in the
loading and wash-coating of catalyst
converter The catalyst converter must be placed
closer to the exhaust manifold, in order to speed
up the working temperature achievement
(light-off).
Electronic Fuel Injection Substitution of fuel
injector material by stainless steel New fuel
injector design to improve the fuel spray New
calibration of air-fuel ratio control and new
Lambda Sensor working range Any component in
polyamide 6.6 (Nylon) that has contact with the
fuel must be substituted by other material or
protected.
Exhaust Pipe The internal surface of pipe must be
protected (coated) The exhaust design must be
compatible with higher amount vapor.
Fuel Pump The internal surface of pump body and
winding must be protected and the connectors
sealed Any component in polyamide 6.6 (Nylon)
that has contact with the fuel must be
substituted by other material or protected. The
pump working pressure must be increased.
Fuel Pressure Device The internal surface of the
fuel pressure device must be protected Any
component in polyamide 6.6 (Nylon) that has
contact with the fuel must be substituted by
other material or protected. The fuel pressure
must be increased.
Motor Oil New additive package.
Cold Start System Auxiliary gasoline assisted
start system, with temperature sensor, gasoline
reservoir, extra fuel injector and fuel pump The
vehicle battery must have higher capacity.
Fuel Filter The internal surface of the filter
must be protected The adhesive of the filter
element must be appropriated The filter element
porosity must be adjusted.
Ignition System New calibration of advance
control Colder heat rating spark plugs.
Evaporative Emission System Due to the lower fuel
vapor pressure, it is not necessary evaporative
emission control.
