The document discusses hydrogen as an excellent source of energy. Hydrogen is carbon-free, clean, lighter than air, and can be produced from sources like water electrolysis and reforming organic substances. It produces only water upon combustion and can be stored safely. Fuel cells can use hydrogen to produce electricity through an electrochemical reaction without combustion. While hydrogen presents challenges related to availability, vehicle and storage costs, it could compete with oil globally if these issues are addressed. The document concludes that hydrogen has the potential to power the 21st century and beyond in a sustainable way.

3. Hydrogen is an excellent fuel for many
reasons. Hydrogen is:
carbon-free
exceptionally clean
lighter than air
odourless
non-toxic
safe to produce, store and transport
easy to store in large amounts
easily produced from many different sources

5. The Nature of
Hydrogen:-
 Disperses quickly
 Is non-toxic
 Produces water upon combustion
 Can be stored safely
 Does not plume
 Does not leach
 Is stable in ambient temperatures

7. HOW SAFE IS HYDROGEN?
o safer than other flammable fuels such
as gasoline or natural gas.
o the International Organization for
Standardization (ISO) is developing
international safety standards.
o Hydrogen has been safely produced, stored,
transported, and used in large amounts in
industry.

8. WHAT ISA FUEL CELL?
 A fuel cell produces electricity through a
chemical reaction, but without combustion
 Fuel cells operates much like a battery,
except they don’t require electrical
recharging.
 It’s an electro-chemical energy conversion
device that produces electricity, water, and
heat.

HYDROGEN
FUEL:-
 Hydrogen is
one of two
natural
elements that
combine to
make water.
 Hydrogen is
not an energy
source, but an
energy carrier.

Challenges:
 Availability.
 Vehicle Cost & Availability.
 Onboard Fuel Storage.

12. conclusion
Hydrogen is the key to bright future.
It able to compete with oil in a global
market, at a fraction of the price.
The fuel that will guide us through the
twenty-first century and beyond for as long
as the sun continues to shine and there is
someone willing to reap its treasure.
