Current Research On Biodiesel Fuel
Presently, there is a continuing research on biodiesel fuel into finding more and more appropriate crops to enhance oil yield. In order to replace fossil fuel usage entirely, huge amounts of land and fresh water would be required to manufacture sufficient oil. Research on biodiesel fuel at present focuses on producing reasonably high oil yields.
Specially bred mustard varieties are found to produce reasonably high oil yields, which are very useful in crop rotation with cereals.
One of the largest diesel fuel users in the world, the US navy and military has the NFESC, Santa Barbara-based Biodiesel Industries involved in developing biodiesel technologies and present research on biodiesel fuel, working for it. A company called Ecofasa with a group of Spanish developers announced a new biodiesel fuel made from trash. This fuel was produced from general urban waste which was then treated by bacteria to produce fatty acids, and later used to make biodiesel.
The current research on biodiesel fuel by the U.S. NREL involved experimenting with algae having a 50% more natural oil content, as a biodiesel source. These algae can be grown on algae ponds at wastewater treatment plants. The research on biodiesel fuel at present on the production of algae to harvest oil for biodiesel has not yet been undertaken on a commercial scale. Alga culture, unlike the crop-based biofuels does not threaten a decrease in food production, as it requires neither farmland nor fresh water. Many companies are pursuing algae bio-reactors for research on biodiesel fuel at present and aim at scaling up biodiesel production to commercial levels.
Some single-celled fungi have been used as biodiesel fuel research by a group at the Russian Academy of Sciences in Moscow, who stated that they had separated large amounts of lipids from these fungi in. an economically efficient manner. More
research on biodiesel fuel using these fungal species is going on at present.
Some researchers recently have successfully produced biodiesel fuel from oil obtained from used coffee grounds. After extracting the oil, it underwent conventional processing into biodiesel. The estimated cost of producing biodiesel following this method could be for about one US dollar per gallon. Further, this research on biodiesel fuel at present states that as there is much coffee around, several hundred million gallons of biodiesel could be made annually using this technique which is not difficult.
