• Substitute for
petrodiesel

Less common types:
• Biobutanol
• Synfuel
Why the Interest In Biodiesel?
 Renewable Resource with the largest potential

to get us off the foreign oil supply

 National Energy Security is an achievable goal

with Algae Oil

 Environmental Enhancement through Zero

Sulfur and the sequestration of CO2

 Economics & Job Creation through keeping

the production of fuels inside the Pakistan
Introduction to algae fuels

Microalgae
• Contains oil
• Processed for biodiesel production

Macroalgae
• Composed of starch and cellulose
• Processed for ethanol production
Algae Oil yield Compared to other
Feedstocks
 Comparative Yields
 Soy Bean

50-65 Gallons Per Acre Per Year
 Camelina 150-400 Gallons Per Acre Per Year
 Palm
400-700 Gallons Per Acre Per Year
 Algae 2,000 to 20,000+ ?? Gallons Per Acre Per Year
Uniqueness of algae fuels

WWT & CO2
capture
Lesser land requirement
 Algae is capable of producing 30 times more oil

per acre than the current crops now utilized for
the production of biofuels.
 Algae could produce up to 94,000 liters of oil per

acre, shrinking land requirements
Adaptability to a range of
environment
Grown under conditions which are unsuitable for
conventional crop production
(marine water, wastewater, open ponds)
Solve the food versus fuel problem
 Does not compete directly with crops grown for food
 Algae can make use of marine and waster water
 Some algae can be grown in desert regions
 Some algae can be grown in ocean environment
 Does not require expensive nutrients for growing
A wide range of fuel products
Biodiesel
Ethanol
Algae

Methane
Hydrogen
Integrated with CO2 capture
Additional Algae Oil Benefits:
 Can be Grown anywhere
 Non-polluting

 Zero Sulfur
 Releases Oxygen (can be captured and sold)
 Eats CO2 (a potentially valuable GHG offset)
 After the Oil is extracted the remaining presscake

(BioMass) is a highly valuable product
How Does Algae Produce Oil?
 Algae is a single cell organism
 Algae feeds on the Hydrogen from the H2O and the Carbon

from the CO2 and through the process of photosynthesis
produces Hydrocarbon Chains and releases Oxygen
 Most strains of the Green and Green-Blue Algae can double

their mass every 24hour growing cycle
 Different strains of Algae produce Algae Oil with slightly

different hydrocarbon chains
How to obtain fuel from algae?
 Picking up the best algae

 Growing the algae
 Harvesting
 Generating the fuel product
Choosing an Algae
 Important

characteristics of Algae
 High % of total biomass is

oil
 Maintains a high % of oil
even under stress
 Compatible with our
regional climate
Where To Grow It
 Extensions onto our water treatment plants
 Clean up our waste and generate fuel

 Agriculture runoff
 Exploit the county’s many farms and vineyards
 Water ponds
 Algae could well grow on salty water as well as soft water
How Is Algae Grown?
 There are 3 methodologies that are currently being used to grow Algae

– with a wide number of variations!
:
1st

Open system
Open Tanks
Pivot Ponds
Open Ponds
Light Pulse Systems
Open Raceway Ponds
2nd vertical systems (Vertigrow’s, Hanging Bags)
3rd Closed systems(photo
bioreactor)

Tubular PBR

Also referred as

Photo bioreactors(PBR)

Flat plate PBR
Bio reactor
 Bioreactors provide fast growth of algae

with the high contents of oil.
 Considerably reduces expenditures of labor &

eliminates complexities in service.

The system can work during long periods
without destruction of culture.

Light in a reactor is taken as much as it
considerably increases its productivity.


 Self-cleaning

Reactors represent closed, controlled,
automated systems.

Oil
Extraction
From Algae
There are three well-known methods
to extract the oil from oilseeds, and
these methods should apply equally
well for algae too:

1. Expeller/Press
2. Hexane solvent oil extraction
3. Supercritical Fluid extraction
1.Pressing oil from the algae





Dry the algae and press the oil from it.
Can retrieve up to 70% of the oil.
While drying must prevent the algae
from becoming contaminated.
Cheapest and simplest method
2.Chemical Oil Extraction
 Use hexane solvents to remove the oil.
 Benzene could also be used.
 Must be careful when using.
 Removes oil out of almost all things.
 About 95% of total oil present in algae

could be extracted.
3.Super Critical Oil Extraction
 Most efficient method.
 Equipment need special containment and

pressure.
 Can extract almost 100% oil by itself.
 Uses carbon dioxide at critical pressure
and temperature (CO2 is almost a liquid).
 Rapid diffusion of the oil.

Product generation via different
methods
 Biodiesel
 Ethanol
 Hydrogen
 Methane

 Electricity – where algae biomass is directly used

for combustion
 Other hydrocarbon fuel, such as JP-8 fuel,
gasoline, biobutanol etc.

Conclusion
 Even with few challenges taken into consideration, algae

biofuel ’s natural advantages look to make it one of the
foremost players in the clean energy market
 Algae biofuel production holds future promise for developing

countries.
• More jobs
• Energy independence
Cost of the pilot project
 Aprox 20,000 to 25,000 in pakistani rupees.

Which include
 Algae cultivation requirements
 Algae drying method
 Algae oil extraction
Thank you!
