The availability of biodiesel around the World is increasing. It is estimated that by 2010 the market for biodiesel will be 7.5 billion litres (2 billion USgallons) in the U.S and 9.5 billion litres (2.5 billion USgallons) in Europe. [16] Biodiesel currently has 3% of the diesel market in Germany and is the number 1 alternative fuel. [17]
Biodiesel is a renewable biofuel, a form of diesel fuel, derived from biological sources like vegetable oils, animal fats, or recycled greases, and consisting of long-chain fatty acid esters. It is typically made from fats. [1] [2] [3]
Biofuel development and use is a complex issue because there are many biofuel options which are available. Biofuels, such as ethanol and biodiesel, are currently produced from the products of conventional food crops such as the starch, sugar and oil feedstocks from crops that include wheat, maize, sugar cane, palm oil and oilseed rape.
The so-called "third-generation biofuels", similar to second-generation biofuels with an emphasize on the use of algae and cyanobacteria as a source of biofuel feedstocks, have an additional advantage as they take up a relatively small fraction of space when compared to first and second-generation biofuel sources, and may also help to reduce seawater eutrophication.
In 2006, Fuel Bio Opened the largest biodiesel manufacturing plant on the east coast of the United States in Elizabeth, New Jersey. Fuel Bio's operation is capable of producing a name plate capacity of 50 million US gallons per year (190 × 10 ^ 3 m 3 /a) of biodiesel. [8] In 2008, ASTM published new Biodiesel Blend Specifications. [9]
In 2010, the United States imported about 4.3 billion barrels (680,000,000 m 3) of crude oil.Add to this about 2.01 billion barrels (320,000,000 m 3) produced in the United States, and the total consumption in the United States is 6.3 billion barrels (1.00 × 10 9 m 3) of crude for 2010.
Biodiesel is a diesel fuel derived from animal or plant lipids (oils and fats). Studies have shown that some species of algae can produce 60% or more of their dry weight in the form of oil. [ 12 ] [ 15 ] [ 25 ] [ 26 ] [ 27 ] Because the cells grow in aqueous suspension, where they have more efficient access to water, CO
The world's largest palm oil biodiesel plant is the €550 million Finnish-operated Neste Oil biodiesel plant in Singapore, which opened in 2011 with a capacity of 800,000 tons per year and produces hydrodeoxygenated NEXBTL biodiesel from palm oil imported from Malaysia and Indonesia. [34] [35]
