In todays presentation we tryIn todays presentation we try
To convey the message why we thinkthat algae biodiesel might have an
important role to play in the Indianenergy independence goal in the nearfuture.
And some other general views.

Why biodieselWhy biodiesel
Biodiesel is the most viable option forIndia today.
Ethanol and biodiesel blends are alreadyin use.
Technically proven.
Infrastructure cost is tolerable andincremental.

Process of making biodieselProcess of making biodiesel
Base catalyzed esterification.
Direct acid catalyzed esterification.
Conversion of oil to fatty acid, then
acid catalyzed esterification.
Followed by proper washing.

Benefits of biodiesel in IndiaBenefits of biodiesel in India
Domestic oil production and economic
growth.
Elimination of foreign oil imports.
Its non-toxic and completely bio-degradable,
hence spills or leaking of underground storage
will not damage environment.
A 100% renewable source of energy.

Why algae as feedstock..Why algae as feedstock..
Among the fastest growing plants; about 50% of their
weight is oil.
Per acre yield is way higher than the other plants.
Wastelands and damp lands which is not required for
any other purpose can be used for algae plantation.
We can even cultivate them in laboratory.
India is a rainy country (mostly).

Advantages of algal biodieselAdvantages of algal biodiesel
Rapid growth rate.
Certain species of microalgae can be harvested on a daily
basis.
Contains no sulfur.
It is non-toxic.
It is highly bio-degradable.
Consume high amount of CO2
,hence they can be used as
antidote to other industrial establishments who produce CO2.

How the algae is selectedHow the algae is selected
Screening is done on the basis of:Safety
Growth rate
Oil concentration and productivityAbility to resist contamination
Ability to grow in continuous culture
Ease of oil recovery
Ease of downstream processing
