The Minuscule Organic Factory By The Name Algae: How Do They Make It Possible?

The catchiest talk around the world is global warming

, and renewable energy. Not because its catchy but because its worthwhile did this article initiate.

Well, all of us know about algae, the slimy creature that tremendously grows above water sources. Possibly thought of as weeds decades before, are now identified as a potential source of alternate fuel.

Fossil fuels, which are currently the biggest source of fuel, are getting depleted in a very fast manner. A potential alternative could only be a source that could be found aplenty.

What makes them a potential source of fuel?

Pond scum (the common term by which algae are referred) utilizes the solar energy incident on them to carryout photosynthesis and produce energy which is stored as oil.

Experts estimate that thousands of gallons of oil can be harvested from algae in a year per acre, when compared to 30 gallons from corn; 50 gallons from soybeans with the same growth parameters.

Now lets see the reasons that make algae a successful fuel source:

Algae are the fastest growing plants in the world

Half of their weight is oil

Algal lipid oil can be converted into bio-diesel for cars, trucks, and for that case even airplanes

Now let us take a closer look at how algae produce oil. Actually micro-algae generate lipids in the form of triacyglycerols (TAGs). The strange fact is that some micro-algae can be triggered to accumulate extensive quantities of lipids, greater than half of their biomass.

Now the question is how do algae grow so quickly?

While some algae reproduce sexually, some asexually, many combine both modes. Some green algae alter the type of reproduction owing to changes in environmental conditions, like lack of moisture or nutrients.

Whats the latest news from algae fuel sector?

There are emerging processes that uses genetically modified (GM) strains of algae and reduce the cost of making fuel. Such GM algae could be grown in enclosed plastic tubes exposed to sun.

Getting back to initial discussion, how well does the algae impact global warming reduction?

Carbon producing power plants, or manufacturing plants, are one of the major contributors for global warming. On the other hand it is interesting to note that this CO2 is used by algae for photosynthesis. Thus the CO2 from such power plants and for that case any such facility could be discharged into algal farms which will utilize them and convert them to energy.
