Algae are cultivated in large pools or farms. Algae converts sunlight water and CO2 into oil which can then be extracted to make biofuels like biodiesel for use in cars and trucks and even jet fuel.

Additionally algal growth does not require potable water or arid land which means that unlike corn algae farming will not take up resources that could be used for growing food.
How does farming algae to produce biofuels work. 2 Challenges of Using Algae as a Biofuel. The algae are also protected from contamination. 1408 billion gallons divided by ten million acres 14080 gallons per acre per year.
Algae to fuels How does algae produce biofuel. If the algae ponds fail to yield enough micro algae oil to produce 14080 gallons of biodiesel per acre per year then ten million acres will not be enough to yield the target goal of 1408 billion gallons per year. Algae are photosynthetic organisms related to plants that grow in water and produce energy from carbon dioxide and sunlight.
Single-celled microalgae can be used to. Algae jet fuel As an added bonus the biomass leftover from the extraction process can be used for pharmaceuticals food and vitamin supplements and animal feed. Governments and corporations are turning to microalgae for biofuel and feedstock solutions.
The algae eat the wastewater and grow until the bag is filled at which point it is removed to be used for making biofuel. Both types of algae are currently mainly used for food in animal feed aquaculture feed and as a bio fertilizer. Algae grow naturally all over the world.
Did you know that half of algaes composition by weight is lipid oil. 1 However the amount of space needed to grow these algae fields is significant as is. According to some algae could potentially produce between 47000 and 308000 litershectare of oil with current technology.
Instead of growing algae outside indoor plants are built with large round drums that grow algae under. But using algae as a biofuel isnt quite as simple as skimming the green stuff from the surface of a pond and pumping it into our gas tanks. Other companies working to produce algae for biodiesel are constructing closed-tank bioreactor plants to help increase oil rates even further.
In order to make biofuels from algae as a substitute for petroleum products one has to address the fact that most species of algae grow fast in comparison to other plants but still not fast enough to make it economical. Under optimal conditions it can be grown in massive almost limitless amounts. Scientists have tried for years to make the algae fatter increasing plant growth and make cells divide faster.
Algae consume CO 2 and on a life-cycle basis have a much lower emissions profile than corn ethanol given the energy used to make fertilizer distill the ethanol and to farm and transport the latter. Reports thus far show that algae farms set up in this manner would be. Scientists have been studying this oil for decades to convert it into algae biodiesel -- a fuel that burns cleaner and more efficiently than petroleum.
Some species of algae produce 50 or more lipids oils through a photosynthetic process. The micro-organisms convert sunlight to energy and store the energy as oil. These oils can be extracted from large algae farms to produce biofuels like biodiesel biogasoline and biojetfuel as well as plastics adhesives and cosmetics.
The extra sun exposure increases the productivity rate of the algae which in turn increases oil production. Algae can yield more biofuel per acre than plant-based biofuels currently about 1500 gallons of fuel per acre per year. Scientists have to use various mechanical and chemical methods or combinations of the two to extract oil from algae and convert it to fuel that is.
Its a fairly simple process.
