scum may soon save the world, and desert
land may soon become the newest landscape for bio-fuel. The industry?
Growing green algae in an enclosed, sustainable enivironment
and making it into fuel.
innovative setup is an experimental bioreactor that takes the
stuff of pond
scum - algae - grows it like crazy and turns
it into "biomass" that can be processed into fuel for
cars and trucks. Even better, the GreenFuel system could help to
clean up coal too.
The idea is that a coal plant's CO2 emissions, rich food for algae,
could be piped into the GreenFuel system, inducing the algae to
grow. Since the algae are essentially eating the coal emissions,
there would be no need to capture and store the CO2.
growth of algae is a clean, sustainable, and
profitable business that only needs the light of the sun, and
a growing environment to proliferate.
Like other plants, they use photosynthesis to harness
sunlight and carbon dioxide, creating high-value compounds in the
process. Energy is stored inside the cell as lipids and carbohydrates,
and can be converted into fuels such as biodiesel and ethanol.
Proteins produced by algae make them valuable ingredients for animal
be converted to transportation fuels and feed ingredients or
recycled back to a combustion source as biomass
for power generation. Best of all, the system needed to grow algae
is does not require
fertile land or potable water.
Growing up to 30 times faster than other terrestrial
plants, algae are regularly harvested for conversion into biofuels,
feed, or can be recycled back to the host facility. Recycling algae
in a closed system reduces the need for fossil fuels.
Algae are different from other energy crops in one
significant way--the entire biomass produced from an algae farm
can be used in end products that are economically valuable. Unlike
comparable crops (corn, sugar cane, rapeseed/canola, palm, soybeans,
sunflower, jatropha, etc.) which typically contain a substantial
amount of wasted biomass, 100% of algal biomass can be used to
create new products.
