Micro algae leading the trend of biofuel

Following the second-generation biofuels, the traditional diesel fuel emerges new alternatives - known as "green gold" of the third-generation biofuels. This emerging biofuel is mainly by algae oil as raw material to produce ethanol, butanol, jet fuel and diesel. The Dutch Wageningen university biology professor Wijffels recently introduces to the reporter, although large-scale production has not yet been applied, but the algae is considered to be a promising bio-fuel.

Although the second generation of fuel no longer need the food to produce the cellulose,which is a big leap, but cost of enzyme used to break down cellulose is too high, so difficult to expand production scale. The third-generation biofuels are mainly extracted oil from algae, no occupation of land and freshwater resources, and algae oil production is very high. Wageningen provide data shows，algae oil of content is 20% to 60%, the average of oil production is 20,000 to 80,000 liters per year, of which palm oil production is 6000 l / ha.

Wageningen related parties, industrial emissions of carbon dioxide can be used in cultivation of microalgae, which can also absorb industrial emissions of nitrogen oxides, consuming large amounts of greenhouse gas carbon dioxide and cleaning the air, but also the growth of algae need the same amount of carbon dioxide, therefore its carbon dioxide emissions close to zero. Meanwhile, growth of microalgae is rapid, when grown in normal biomass can double every 24 hours, and can be harvested throughout the year, the requirements for growth environment is very low.

Although microalgae of high-density output in per unit area is its greatest advantage. However, the current level of technology, there are energy consumption per unit area is also large, the problem of high input costs culture microalgae in cultivating microalgae. Wageningen University has invested about 500 million euros for the algae test plant, but they estimated that the current production cost of per hectare of algae is about 10 euros / kg, 100 hectares of production cost is 4 € / kg, and 100 hectares of the future cost of production is likely reduced to 0.4 euros / kg.

Wageningen university and the Dutch research center of researchers in 2010's "Science magazine (journal Science)" said, in the past two decades, microalgae biodiesel production costs continued to decline, from a few hundred dollars / gallon down to a few dollars / gallon, within the next decade the cost of algae biofuel will be balanced with conventional fuels.

The cost of extraction and harvesting of algae is also high. Currently, the main method of oil extraction from algae are solvent extraction, mechanical pressing, supercritical carbon dioxide extraction and other methods, these methods have the problem of large energy consumption and cost of high solvent loss.

In addition to cost, researchers have said that algae biofuels also have some impact on the environment. University of Virginia, studies have reported that, compared with other biological materials, such as corn,the algae biofuel consuming more energy, need more water in the production process.
