Using hydrogen as fuel to power cars has been an idea that
has been around since the early part of the 1970’s. Researchers
and environmentalists have been backing it because they believe
that hydrogen cars are important to the future of our world.
Fossil fuels will not last forever. We will run out of them and
if we don’t have an alternative, we are basically out of luck.
Using hydrogen as fuel will not contribute to greenhouse gases
whereas fossil fuels are the major contributor to the pollution
of our atmosphere.
There are studies that have been done that indicate an issue
with hydrogen production. The issue is that when it is produced
in an improper manner, it emits nitrogen oxides. Nitrogen
oxides cause acid rain. This means that though it helps in one
area, it can cause problems in another area. But this can be
prevented. Nitrogen oxide is not produced when the engine is
timed correctly and hydrogen concentration is optimized.
There are two different approaches to using hydrogen as fuel
to power cars. One approach uses many fuel cells. The other
uses modification of the internal combustion engine to enable
the use of hydrogen.
Hybrid vehicles use a combination of petroleum based fuel
(gasoline) and hydrogen. Instead of one tank, there are two:
one for gasoline and one for the hydrogen. Using hydrogen
reduces the amount of gasoline that we use making this a great
alternative not only because we will get better gas mileage,
but because the way it is done makes it so oxygen is released
into the air instead of carbon.
When using hydrogen fuel cells, the motor vehicle runs on
hydrogen and electricity. The hydrogen in water reacts with
oxygen, producing vapor and electricity for powering the
car.
The only problem we have right now for using hydrogen as
fuel for cars is that it cannot yet be used as an exclusive
source of energy. For now, we need to use fossil fuels. We need
to figure out how to extract the power from the hydrogen. That
is what scientists and researchers are working on right now - a
way to extract and use hydrogen exclusively that does not cost
an arm and a leg. In order to store hydrogen, it must stay in a
liquid form. The temperature must be 253 degrees Celsius in
order to stay liquid. If it gets any warmer, it will turn into
gas. Right now, this calls for huge storage tanks that are well
insulated and vented. Complete hydrogen power is not yet
cost-effective.
This is the major hurdle we need to get over before the full
benefits of using hydrogen as fuel are seen. In addition, we
need to have more hydrogen stations available. What is the
point of having one of these cars if you don’t have a place to
refuel? Last of all, hydrogen powered vehicles are too
expensive to be a viable option for the general public.
These issues must be resolved before the world can get the
full benefits of using hydrogen power in its vehicles.
There is some hope on the horizon. Many car companies are
already designing hydrogen powered motor vehicles. The prices
for these are not much more than for the gasoline powered cars
we are using right now.
If you would rather not wait for science and research to
solve all the problems, you do have the option of turning your
vehicle into a hybrid or having your car converted into a
hydrogen/electric car. The second option will be more expensive
and you will have the challenge of finding hydrogen stations,
but you will also be among the first to use hydrogen as fuel
for motor vehicles.
We can fully expect that using hydrogen as fuel to power
cars will be the norm in the future. Just remember that we
don’t have to wait for this to happen before we take other
steps to improve our environment.
