BIOFUEL FROM ALGAE

NEED OF ALTERNATIVE ENERGY SOURCES
60% of total energy resources already used by us in last 200yrs.
Remaining 40% will last few decades only. Formation of fossil fuel takes million yrs Again the shortage of energy comes in
picture. Thus we are going face energy crisis in the
future. The only way to get out of it , is to
introduce alternate methods using renewable sources.
3 GENERATIONS OF BIOFUEL 'First-generation
biofuel was made from sugar, starch, vegetable oil, or animal fats using conventional technology.
Second generation biofuels was made from non food crops
THIRD GENERATION “SOLAR BIOFUEL” is a biofuel from algae
THIRD GENERATION OF BIOFUEL
Algae fuel, also called oilgae isbiofuel from algae.
Algae are low-input, high-yield feedstock to produce biofuels.
Relies on the fact that some algae naturally produce oil and this can be collected without killing the algae.
BIOFUELS• Substitute for
petrodieselBiodiesel
• Subsitute for
gasolineEthanol
Less common types:• Biobutanol• Synfuel
INTRODUCTION TO ALGAE FUELS
Microalgae• Contains oil• Processed for biodiesel
production
Macroalgae• Composed of starch and
cellulose• Processed for ethanol
production
What are algae?They are basic from plant kingdom. Divided further into :
Algae
WHY ALGAE ENERGY CAN BE A FUTURE FUEL?
Grown under conditions which are unsuitable for conventional crop production.
Micro-algae are the fastest growing photosynthesizing organisms.
Under optimum growing conditions micro-algae are reported to produce up to 15,000 gallons of oil/acre/year.
Capable of fixing CO2 in the atmosphere, which are now considered a global problem.
Algae biofuel is non-toxic, contains no sulfur, and is highly biodegradable.

WHY ALGAE ENERGY CAN BE A FUTURE FUEL?
Algae fuels
Higher oil yield
Lesser land requirement
food vs. fuel
Range of products
Adaptability

Additional features of algae energy-Solid waste from algae energy can be
severed as feed for cattle.Extracted proteins can be used in human
food chain.As it is a low cost waste water treatments.

“ULTIMATELY A FUTURE

CULTIVATION OF MICROALGAE SPECIES
Cultivation is mainly done in-Open systems
Closed systemsalso known as Photo-bioreactor
Algae Cultivation – Open pond / Raceway pond
ADVANTAGES OF OPEN PONDS
Less initial cost Simple construction Almost no electrical power
required Easy install in remote areas
CLOSED SYSTEMS(ALSO REFERRED AS PHOTOBIOREACTORS)
Tubular PBR
Flat plate PBR
THE CIRCUIT OF INSTALLATION OF A BIOREACTOR
Provide fast growth of algae with the high contents of oil.
Economy of space.. The reactor considerably reduces expenditures of labor The system can work during long periods of time Light in a reactor is taken as much as it considerably increases its
productivity. The bioreactor is equipped with convenient system of self-
cleaning that reduces its pollution. Reactors represent closed, controlled, automated systems of
continuous action that allows to support hygiene of cultures in easier way.
Ecological parameters of system also easily give in to management.
The size of a reactor is not limited.
The Advantages Of A PhotoBioreactor
A Detailed Process of Biodiesel from Algae:
Solar biofuel type
Indian steps towards oilgae
• Indian oil is the 18th largest petroleum company in the world, and is currently India’s largest company by sales.
• PetroAlgae has signed an agreement to license its technology for producing and harvesting algae for fuel to Indian Oil
Indian steps towards use of oilgae
ADVANTAGES OF BIOFUEL
Clean energy. Decays naturally in few days. No harmful gases when utilized. Hygiene fuel in terms of cleanliness. Can be used in diesel cars without any much
changes. Improves mileage & life of engine of car.
CONCLUSION
So that days are so Snot far when almost all cars in world will run on bio fuel which is obtain from highly efficient source- algae
And soon we will have a eco friendly drive Thus helping us to take one more step
towards making human activities more friendly with mother earth
THANK YOU……..
Cleanliness “Eco-friendly”ness is next to godliness…………
