2 Alternative Fuels HYDROGEN Hydrogen Most abundant element in the universe Composes about 75% of the universal elemental mass Atomic number 1 Diatomic gas: H 2 Colorless, odorless and tasteless

3 Alternative Fuels HYDROGEN Hydrogen Internal Combustion Engine Hydrogen gas stored in pressurized tank Hydrogen burns in a modified ICE Power output for Hydrogen is 42% more than gas using carburetors and 20% with injectors Combustion formula including nitrogen in the air is H 2 + O 2 + N 2 = H 2 O + N 2 + NO x

4 Alternative Fuels HYDROGEN Hydrogen Fuel Cells Hydrogen can be produced as a by-product, reformation or electrolysis Hydrogen can be stored as a gas or liquid Hydrogen is reacted with oxygen to electricity An electric motor turns the transmission U-Tube Video: how fuel cells work http://www.alternative-energy-news.info/technology/hydrogen-fuel/

5 Alternative Fuels HYDROGEN CONS Hydrogen is not naturally occurring: it must be produced Fuels are expensive Fuels currently last 7300 hours 2 PROS Tue Zero Emission Vehicle No operational greenhouse gas emissions Very highly efficient More energy pound for pound than gasoline : better mileage
