Brazilian experience with fuel grade ethanol started in the 1920’s. Variable ethanol content in gasoline

depending on ethanol availability…until

1973 OIL CRISIS & LOW SUGAR PRICES

1975

• GASOHOL REGULARLY AVAILABLE SINCE 1977

• NEAT ETHANOL FOR ALCOHOL CARS AVAILABLE COMMERCIALLY SINCE 1979

(over 5 million ethanol fueled vehicles produced in Brazil)

alcohol content ºGL (at 20 ºC)

Type

Under Brazilian regulations two types of fuel ethanol are produced:

• Anhydrous: blended with automotive gasoline

• Hydrous: used as a neat fuel in vehicles or blended with gasohol by the consumer in FFV

FERTI-IRRIGATION WITH STILLAGE

ferti-irrigation with stillage helps to reduce use of water& chemical fertilizers and recovers soil fertility

bagasse

electricity

The sugarcane industry produces its own thermal & electric energy using bagasse as a fuel in co-generationsystems and it sells theexcess electricity to the publicgrid (presently 600 MW)

The Brazilian Ethanol Experience

% Ethanol in Gasoline(gasohol)

1977: 4.5%1979: 15%1981: 20%1985: 22%1998: 24%

1999: 20 to 24% SINCE 200220% to 25%

- Brazilian ethanol, gasohol & Flex-Fuel vehicles

- Imported gasohol vehicles and engines

• energy security & diversification

• technology development

• environmental benefits

• balance of payments

• jobs

• Vehicle can operate on gasoline or ethanol or any ethanol-gasoline blend without any special requirement

• Consumers’ good acceptance: 2004 sales projections !!!! 300,000 Flex Fuel units

“FLEX FUEL” Vehicles

The FLEX FUEL Concept

ENGINE

ECU

CatalyticConverter.

Exhaust

O2 Sensor

Sensor originally used for emission control measures O2 contentin exhaust gas and sends a signal to the Engine Control Unit(ECU) indicating the level of ethanol in the fuel line ! ECU automatically recalibrates spark timing and fuel injection.

Vehicle Emission Reductions Related to Fuel Ethanol Use in Brazil

Lead additives banned since 1990

Reduction of SOx

Reduction of PM (carbon and sulfate particles)

VOC´s with lower toxicity & photochemical reactivity

CO: Higher reduction in older E100 (up to 70%) and gasohol (up to 40%) vehicles in comparison withethnaol-free gasoline

Biodiesel in Brazil

• Since the 1920’s ! initiatives to promote use of vegetable oilsin Brazil

• During the 1980’s: Pró-óleo and OVEG Programs ! limitedresults

• In 2002 MCT implemented the Research & TechnologyDevelopment PROBIODIESEL National Network

• 2003 Interministerial Commision evaluated feasibility of Biodiesel in Brazil and set recommendations for a program

• 2003: first Biodiesel specification (ANP 255/03)

• 2004: permission to use 2% biodiesel + 98% diesel blends (B2)

• December 6 2004: announcement of National Biodiesel Program

• Biodegradable• Reduces emission of:

– Particulates– Carbon Monoxide– Sulphur oxides– Hydrocarbons– CO2

On a well-to-wheel basis it is estimated that:

biodiesel reduces CO2 emissions by 78% comparedto diesel oil

BIODIESEL – Environmental Aspects

Benefit is proportional to theamount of biodiesel used

Soybean biodiesel energy balance3.2 output energy/input fossil energy

For diesel oil the ratio is 0.83
