What biofuels are produced from algae?
The carbohydrates (sugars) from algae can be fermented to make additional biofuels, including ethanol and butanol, as well as other products such as plastics and biochemicals. Biomass from algae can be used for pyrolysis oil or combined heat and power generation.
Can you make biofuel out of algae?
Algal oils, just like oils produced by soy, canola, palm and the less-known jatropha plants, can be made good biodiesel feedstocks through transesterification. In that process, a catalyst creates a biodiesel fuel (consisting of fatty acid methyl esters) by hydrolyzing and methylating fatty acids in the oils.
Which algae is best for biofuel?
Highest-yielding algae. The algae used in biodiesel production are usually aquatic unicellular green algae (Chlorophyceae). This type of algae is a photosynthetic eukaryote characterized by high growth rates and high population densities.
Why is algae not used as biofuel?
And for the algae in these ponds to produce biofuel, it would require fertiliser equivalent to 50% of the current total annual EU crop plant needs. Ironically, such ponds would also need to be located near heavy industry which produces CO₂ to provide the level required by the microalgae for photosynthesis.
Why is algae biofuel so expensive?
The production cost is high because of the energy required to circulate gases and other materials inside the photo bioreactors where the algae grow. It also takes energy to dry out the biomass, and Solix uses far less water than other companies (see Cutting the Cost of Making Algae by 90%).
Why is algae bad for biofuels?
Algae production consumes more energy, has higher greenhouse gas emissions and uses more water than other biofuel sources, like corn, switch grass and canola, Clarens and his colleagues found by using a statistical model to compare growth data of algae with conventional crops.
How long does it take to turn algae into a biofuel?
Researchers at the Pacific Northwest National Laboratory developed an innovative process that turns algae into bio-crude in less than 60 minutes.

Is algae oil sustainable?
The use of algal oils remains a proven, sustainable alternative to fish oils and will form an increasingly large proportion of the EPA/DHA market because of the limitations on fish oil production.
