Presentation transcript:

Gasoline is made from fossil fuels …mostly oil

Fossil Fuels Oil pumped from the ground

This type of fuel will not last forever

So, a new type of fuel needs to be made … An Alternative Fuel

TOMORROWS ENERGY HYDROGEN

The most abundant resource in the universe

Hydrogen Atom

H O H Defined: Hydrogen Electron An atom that has only one electron Hydrogen is a gas and when combined with oxygen… forms water H2O Symbol H

HOW DO WE MAKE HYDROGEN ?

Hydrogen gas can be made from water H20 But, no.. You can’t just put water in your car to make it run.

Electrolysis Sending electricity through water will split the molecules of water apart, creating ………… Hydrogen Oxygen Scientific Fact

Electricity is used to split the water molecule into its separate parts

Now that we have hydrogen

Defined: A fuel -cell is a device that converts this hydrogen into electricity … Emissions OUT Is Water IN

Fuel Cells

WATER VAPOR HYDROGEN ATOM IS SPLIT

Fuel cell stacks…..

SMALL FUEL CELL

Fuel Cell Hydrogen tanks Electric Motor Hydrogen enters the fuel cell to create electricity that drives the electric motor for the wheels.

ELECTRIC MOTOR

HYDROGEN FUEL

SKATEBOARD DESIGN

The electric motor that will be used to drive the car of the future

FUEL CELL CAR Only emissions out the exhaust is water vapor

Future Cars that run on Hydrogen

Example of a fuel-cell car

Hydrogen filling station

HYDROGEN TANK Under very high pressure

2016 Toyota Mirai Hydrogen Vehicle Value $ 58,000

Toyota Mirai at a hydrogen filling station

In the last few years three automakers--Toyota, Honda, and Hyundai have produced new cars. California is starting to build hydrogen filling stations. Range is comparable to gas-powered cars, about 300 miles. Automakers have avoided building fuel cell cars mainly because of the lack of filling stations. Electric Power

Two carbon-fiber tanks store 11 pounds of hydrogen fuel under very high pressure (10,000 psi). In emergencies ( a crash), sensors trigger shutoff valves to keep hydrogen from escaping the tank.
