Green fuel, also known as biofuel, is a type of fuel distilled from plants and animal materials, believed by some to be more environmentally friendly than the widely-used fossil fuels that power most of the world. In the desperate search for alternative energy sources, green fuel has evolved as a possible fueling option as the world drains its fossil fuel resources.

3. ❑Excessive usage of fossil fuels have
led to the depletion of their
reserves and also resulted in the
degradation of the environment.
This has led the researchers to
come up with renewable and eco
friendly counterparts.
❑There are several renewable
resources present which include
green fuels.
❑Green fuels are future generation
renewable resources which will be
revolutionary in coming days

5. Global Warming Mechanism

6. Hydrogen
• UNLIKE fossil fuels, hydrogen is in
abundance.
• In fact, hydrogen makes up 75% of
the universe we live in, so there’s no
danger of it running out any time
soon! The Hyundai ix35 was the
world’s first production hydrogen Fuel
Cell Electric Vehicle (FCEV), with
energy created using the process of
passing hydrogen through a fuel cell.

7. Electricity
MORE and more cars are heading
down electric avenue. However,
there’s still a long way to go before
we can consider electric vehicles
(EV) to be truly mainstream.

8. Biodiesel Liquefied
petroleum gas
Ethanol
ETHANOL is an alternative to petrol
and can be combined with regular
unleaded fuel in any concentration, up
to 100% pure ethanol. In the UK,
ethanol accounts for up to 5% of the
fuel you’ll buy from a petrol station, but
there are plans to increase this to 10%.

9. What is Algae?
„Simple plant
„Most live in water
„Photosynthetic
‡Capture light energy
Convert inorganic to
organic matter

10. What is Algae?
„„Use lipids and oils to help
float in water
„Range from small, single-
celled species to complex
multicellular species, such as
the giant kelps

11. WHY ALGAE FUEL?

12. Production of algae fuel
There are two major processes to
manufacture
biodiesel from algae
ALGAE
DRY
ALGAE
TRIGLYCERI
DES
HEXANE
METHANOL
TRANSESTERIFICATION
BIO-DIESEL
DEHYDRATION

13. Hydrothermal
liquefaction(HTL)

14. ADVANTAGES
❑ Renewable
❑ Eco-friendly
❑ Fixes carbon
❑ Omnipresent
❑ Solves 3 major social
problems
a.Power necessity
b.Checks global
warming
c.Disposal of
organic wastes.

15. ADVANTAGES

16. Biodiesel From Plants
Rapeseed oil(canola),
jatropha, sugar molasses
and soybean oil.

17. Plastic Fuels
O2 free
chamber
Exhaust
gases for
purification
H
E
A
T
WASTE
PLASTIC
RECYCLE
OR
SLUDGE

18. Conclusion
These alternative sources of
energy, if adopted helps in
decreasing the environmental
pollutants emitted by fossil fuels
and chemical industries.
On the other hand some
techniques of green fuels utilize
the pollutants and produces
biofuels. This way already existing
pollution is decreased and the
new products are eco-friendly and
cause no harm to the
environment.
Thus with green fuel
technologies it’s always a win-
win situation.
