INTRODUCTION
 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
Global warming effects
Global Warming Mechanism
What is Algae?
 „Simple plant
 „Most live in water
 „Photosynthetic
‡Capture light energy
Convert inorganic to organic matter
 „Use lipids and oils to help float in water
 „Range from small, single-celled species
to complex multicellular species, such as
the giant kelps
WHY ALGAE FUEL?
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
Hydrothermal liquefaction(HTL)
ADVANTAGES
 Renewable
 Eco-friendly
 Fixes carbon
 Omnipresent
 Solves 3 major social problems
a. Power necessity
b. Checks global warming
c. Disposal of organic wastes.
ADVANTAGES cntd.
Biodiesel From Plants
Rapeseed oil(canola), jatropha, sugar
molasses and soybean oil.
Plastic Fuels
O2 free
chamber
Exhaust gases for
purification

E
A
T
WASTE PLASTIC RECYCLE OR
SLUDGE
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.
