OUR CAR AS POWER PLANT ENERGY EFFICIENCY
GASOLINE CAR COMPARED TO FUEL CELL CAR
GASOLINE CAR FUEL CELL CAR
Extraction oil + transport 95% Extraction gas + transport 95%
Crude oil to gasoline 90% Gas to hydrogen (H2) 80%
H2 storage + compression 85%
IN THE GASOLINE CAR IN THE FUEL CELL CAR
H2 de-compression 90%
Fuel cell 60%
Combustion engine 35% Electric motor 95%
Standby/Idle 85%
OTHER SYSTEM COMPONENT EFFICIENCIES THE SAME
Overall Effi ciency 25% Overall Effi ciency 33%
We need to produce hydrogen from gas, store and com-
press it to put it in the tank of the car and decompress it
in the car to feed it into the fuel cell. Of course this leads
to losses, overall we estimate an effi ciency of about 60%.
Then we have the fuel cell itself that converts hydrogen
into electricity with an effi ciency of about 60% also.
Overall the energy effi ciency comparison based on the
same system components is about 25% for a modern
gasoline car and about 33% for our fuel cell car. It means
an overall energy effi ciency improvement of 30% in our
transport system. This would imply also that the carbon
dioxide emissions will be at least 30% lower. Additionally,
a fuel cell car has no local pollution and is very quiet.
