Once hydrogen cars are the status quo, the U. S.
can decrease its dependency upon foreign oil, bring
down costs at the pump and cut down on greenhouse
emissions that bring about global warming. There
are already many hydrogen cars on the road.
Current
fossil-fuel automobiles give off all sorts of pollutants
such as carbon dioxide, carbon monoxide, nitrous
oxide, ozone and microscopical particulate matter.
"Green
cars" deal with these consequences but only
hydrogen cars hold the promise of zero pollutants.
Unlike
many of the hybrid cars presently for sale, hydrogen
cars promise naught discharge engineering, where
the only spin-off from the cars is H2O vapor.
So
what exactly is a hydrogen car? A hydrogen vehicle
is a vehicle that uses hydrogen as its on-board
fuel. There are hidden costs associated with cars
of this technology.
Hydrogen
fuel cells are costly to produce and fragile. Many
designs require rare substances such as platinum
as a catalyst in order to work properly.
Freezing
conditions are a major consideration. Fuel cells
produce water and therefore in freezing climates
- water will obviously freeze.
Service
life is not so good for transport type vehicles
like buses.
Replacement
of standard gasoline fuel systems will obviously
take a long time.
Hydrogen
internal combustion engine cars are different from
hydrogen fuel cell cars.
The
hydrogen internal combustion car is a slightly modified
version of the traditional gasoline internal combustion
engine car. These hydrogen engines burn fuel in
the same manner that gasoline engines do.
Can
you imagine that? Running your car on water?
