2. Harnessing Hydrogen for
Power:
Hydrogen Cars

3. What exactly is a Hydro gen Car
 In ahydrogen car, itsprimary sourceof power isfrom breaking down hydrogen

5. Ways of Getting Hydrogen
These are the important ways now used :
S.S

6. BMW’s project for hydrogen
car
 BMW took the initiative step
to create a hydrogen fuel car
 IT tested it’s BMW7 first
time at aug 7 2015
 it accelerated 0-60 in 9.5 sec
only

8. Hydrogen fuel cell:-
 It gets hydrogen from
hydrogen tank and air
from atmosphere.
 it generates power by
using these two gases
 The power can be
depends upon no. of
individual fuel cells
used(0.7v)

9. Hydrogen tank:-
 It is present at the back
portion of the car.
 It as made up of impact
resistant polymer
Power control unit:-
 It governs the flow of
power

10. IMAGES OF MOTOR AND
BATTERY
IT propels the car more
smoothly and efficiently
IT stores energy from
the regenerative
braking

11. Comparable Efficiencies
Hydrogen Fuel cells at over 50% efficiency
Fossil fuel powered car at 10% - 20%
efficiency
Hybrid powered cars have 30% - 35%
efficiency
Ethanol is less efficient than fossil fuel
- ethanol gets 20% less mpg than fossil
fuels

12. Advantages
Zero emissions (pure water is produced)
No dependence on foreign oil
Ability to harvest solar and renewable energy
Not many moving parts in a vehicle (more
mileage before things start breaking)
Hydrogen weighs less than gasoline (vehicles
would not need as much energy to move)

13. Companies Getting Involved
 Ford
- P2000
 Honda
- FCX
 BMW
- Hydrogen 7
 Mazda
- Wankel motor
 General Motors
- Sequel

14. If use this technology we can completely reduce the wastage of
fossil fuels. We can also reduce the cost of fuel
