Biodiesel has attracted a great deal attention recently as an alternative fuel due to increasing fuel prices and the … imperative to reduce emissions. Among a wide range of biodiesel resources, microalgae are a promising alternative fuel source … because of the high biomass, lipid productivity and environmentally friendliness. Microalgae is also a non-edible food …

from a previous 4% from 2010. In 2012 the fuel blend reached 3%, with approximately 70 million L of biodiesel and 56 … Ireland for biodiesel was 2.3% and for bioethanol was 3.7% which equates to approximately 37.5 million L of biofuel for the … microalgae (for biodiesel) and macroalgae (for bioethanol) could meet this shortfall for indigenous Irish production. This paper …

Cultivating microalgae at industrial scale for biodiesel production required substantial amount of mineral fertilizer …. Total lipid of 18.1% from C. vulgaris biomass was successfully extracted and the fatty acids methyl ester profile was proven … to be suitable for making biodiesel. …

Microalgae have been proposed as possible alternative feedstocks for the production of biodiesel because of their high …, however. There is a need to determine whether microalgal biodiesel can deliver more energy than is required to produce it. In … this work, net energy analysis was done on systems to produce biodiesel and biogas from two microalgae: Haematococcus …

The entire life cycle of biodiesel produced by microalgal biomasses was evaluated using the method of life cycle …, esterification, biodiesel transportation and biodiesel combustion. The investigation results show that the fossil energy requirement … for the biodiesel production is 0.74MJ/MJ biodiesel, indicating that 1MJ of biodiesel requires an input of 0.74MJ of …

Increasing demand for transport fuels has driven China to attach great importance to biodiesel development. To evaluate … the environmental impacts caused by producing and driving with biodiesel made from soybean, jatropha, and microalgae under … depletion potential (ADP), global warming potential (GWP), and ozone depletion potential (ODP) in the life cycle of biodiesel …

This paper examines the competitiveness, role, and impact of microalgal biodiesel in the 21st century using a global … competitiveness of microalgal biodiesel decreases as CO2 stabilization constraints become more stringent. The share of microalgal … biodiesel and renewable jet fuel produced from it in total global final energy consumption over the time horizon 2010–2100 is 5 …

issues are also present: the relatively low microalga intrinsic lipid productivity; the maximum cell concentration attainable …
