8 Central Pros and Cons of Algae Biofuel | Green Garage
Biofuels are produced from living organisms or from metabolic by-products (organic or food waste products). In order to be considered a biofuel the fuel must contain over 80 percent renewable materials. It is originally derived from the photosynthesis process and can therefore often be referred to as a solar energy source. There are many pros and cons to using biofuels as an energy source. This page contains articles that explore the many biofuel technologies.
8 Central Pros and Cons of Algae Biofuel
If its production and sale could be made to be economically competitive with other forms of energy, algae biofuel would certainly become an important energy source that will fuel the world to a greener future.
However, research on algae biofuel was abandoned to focus on ethanol, resulting in the 1995 closure of the Aquatic Species Program, the US Department of Energy program that focused on developing algae fuel.
Photosynthesis and photorespiration in freshwater green algae
However, with limited public knowledge and limited governmental financial support, the development and production of algae as a source of biofuel is stunted.
Algae-based Wastewater Treatment
Algae production farms for high value food and feed supplements, operating since the 1980s, such as Earthrise Nutritionals in California and Cyanotech in Hawaii, ranged up to 50 hectares in area. Today, algae biofuel ventures are looking to scale up from 100 to 1000 hectares and even larger to achieve the economies of scale to be worthwhile. Here are artist conceptions of outdoor algae biofuel farms of the future.
An Algae Bioreactor From Recycled Water Bottles: 7 …
One of the first large scale algae biofuel farms is now underway. Sapphire Energy has announced the first phase of their commercial demonstration algae-to-energy facility is operational in Columbus, New Mexico. Today, the cultivation area consists of 1.1 and 2.2 acre ponds. At completion, Sapphire projects the 300 acres (120 hectares) of algae cultivation ponds and processing facilities will produce 1.5 million gallons per year of crude oil.
Scalable Algae Microfarms: Part 1 | Algae Industry Magazine
Algae Biofuel is just algae biofuel derived from algae lipids (fats). Algae has a LOT of lipids, up to 60% by weight. (HowStuffWorks, "")

Algae can be cultivated very fast, within 10 days. This is much better than other types of biofuel such as corn, which may take weeks or even months to cultivate. However, the cost of cultivating algae is very high. This is the biggest problem of algae biofuel and is hindering the industry from developing as fast.
Marine Biological Lab developing new seaweed harvest methods
Research into algae for the mass-production of oil is mainly focused on microalgae - organisms capable of photosynthesis that are less than 0.4 mm in diameter, including the diatoms and cyanobacteria. Macroalgae, on the other hand, such as seaweed, are less prefered than microalgae. The preference towards microalgae is due largely to its less complex structure, fast growth rate, and for some species high oil content. (Wikipedia, "")
