Hydrogen is a gas that could be found in the universe and
it is the simplest one. Our sun and other stars are made
of hydrogen. Inside the sun, hydrogen atoms change to
This process gives us plenty of energy, which is called
fusion. It gives us heat and makes the wind blow and rain
fall. It makes plants grow.
There is no pure hydrogen on earth. It is always mixed
with other elements.
If it is combined with carbon, it would make coal or
methane (CH4). With oxygen it makes water. It is the
lightest element and has the highest energy content of any
fuel by weight.
HYDROGEN CAN STORE ENERGY
People like to use renewable energy because it is clean
and friendly with environment. Renewable energy like wind
and sunlight are always available when we need them.
Hydrogen is a good source of energy, which can be stored
until it is needed.
HYDROGEN AN ENERGY CARRIER
We use more and more energy every day. Most of the energy
we use is electricity. This is called secondary source of
energy, which sometimes is called energy – carriers.
We usually use coal to generate steam power in order to
produce electricity.Electricity made our life easier.
It gives us heat, light, cold water, computers and so on.
If we had to burn coal to generate energy, the life would
have been very difficult.
Hydrogen is an energy carrier (or storable) that can be
used in those places where it’s hard to use electricity.
Sending hydrogen from one point to another by pipes is lot
cheaper than transmitting electricity.
HOW IS HYDROGEN MADE?
Hydrogen does not exist on earth as a gas; therefore we
separate it either from water or natural gas. Making
hydrogen is very expensive, so, new technology should be
developed to bring the prices down.
USES OF HYDROGEN
To day more than 9 millin tons of hydrogen are produced in
the U.S.A. This much hydrogen is enough to warm 5-8
million homes or run 20-30 million cars. Industries also
use hydrogen to make different products. NASA has used
this gas in its space program for many years.
Hydrogen is used in space shuttles, to place it in the
orbit. The only thing remains from burning the hydrogen is
pure water. Hydrogen is also used to make electricity. But
generating electricity from hydrogenisveryexpensive.
HYDROGEN AS A FUEL
Building a hydrogen-powered plant is not possible now,
because manufacturing costs are very high. But in near
future hydrogen will be added to gasoline to increase its
performance and reduce nitrogen oxides, which increases
ground – level ozone pollution.
It would take 10-20 years to make commercial hydrogen
THE FUTURE OF HYDROGEN
Hydrogen will become our future fuel but before that, new
systems of storage and transportation should be built. The
technology of making the gas must be improved. Also people
should be educated to use it. The U.S.A. government’s goal
for hydrogen is to produce at least 10 percent of the
total energy by 2030, using hydrogen as an energy source.
