Microalgae biodiesel

The principles of sonochemistry can also be applied to disrupt different species of oil-bearing microalgae cells. Detailed experimental results are necessary to support the cost-effectiveness and industrial scale applicability of ultrasound for microbial lipid extraction, and subsequent biodiesel production in comparison to conventional methods (Mata et al., 2010).

Many microalgae can be converted to biodiesel using the existing technology (17). 

It has been concluded that microalgal biodiesel is the only renewable biodiesel that has the potential to completely displace liquid transport fuels derived from petroleum. Existing demand for liquid transport fuels could be met sustainably with biodiesel from microalgae, but not with bioethanol from sugarcane (17).

Earlier studies on microalgae took place during 1978-1996 with projects funded by the National Renewable Energy Lab (NREL). The major conclusion of the study in a closeout report by NREL in 1998 showed that algae oil-derived biodiesel is, even with all the improvements, at least two times higher in cost than crude oil-derived diesel. Other results of the NREL report (Ref. 91, pp. 28-31) indicate that some species contain substantial amounts of unusual components not found in other plants such as C13-0, C14-1, C15-0, C16-1, and even some with methyl-branched fatty acid content in concentrations of 3-5% to as much as 15-20%.
