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.
