ALTERNATIVE FUELS By Sergio Benitez

DEFINITION OF FUEL FUEL: A material used to produce heat or power by burning

PRESENTATION OUTLINE History E85 Biodiesel Hydrogen Comparison to Petrol

HISTORY 1813: Francois Isaac De Rivaz

HISTORY 1897: Rudolf Diesel

HISTORY 1975: Brazil Programa Nacional do Álcool

E85 A mixture of 85% Ethanol and 15% Gasoline Pros  Higher Octane Rating  Reduces dependence on Oil  Reduces tailpipe emissions  Usually cheaper than 87 octane gasoline Cons  Production process does add extra green house gases to atmosphere  Use of corn crop for fuel instead of food  Lower energy content than gasoline  Limited distribution network

Biodiesel Vegetable oil or animal fat based diesel fuel Comes in different mixtures, B20, B100 Waste vegetable oil can be used Pros  Burns cleaner than petro diesel  Lubricates very well  WVO sometimes free  Reduces petroleum consumption Cons  Lower energy content than petro diesel  Food or Fuel  Use of limited resources for crop production  Not a total replacement for petrol  Limited distribution network  Clearing of forest for biodiesel crops

HYDROGEN Burned with Oxygen Bi product is water H2O Pros  Much lower emissions than Petrol  Huge supply of hydrogen  Reduce consumption of Petrol  More energy per weight than gasoline  Higher thermal efficiency than gasoline engine Cons  Most common production method burns fossil fuels  Lower volumetric density than gasoline  Expensive to produce  No distribution network  Difficulties in transportation and storage
