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
TRIGLYCERIDES
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
HEAT
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.
