“…fatty acid alkyl esters), transesterification of the algal oil extracted from dry biomass has been demonstrated. 37 Meanwhile, studies showed that traditional solvent-based lipid extraction and direct transesterification techniques are inhibited when performed in the presence of a water phase. 34,38 In order to avoid drying algae and improve the transesterification efficiency, several methods including acid and base hydrolysis, 39 employing alternative solvents, 40 and super critical fluids, 41,42 have been developed to process wet algal biomass for oil extraction and/or in situ transesterification.…”

“…The former is the oldest method involving a simple and inexpensive process, compared to the latter, which enjoys high productivity rate, less maturity time and the capacity to selectively produced high lipid content using desirable algae species. Algae contain lipids, carbohydrates and complex oil depending on their species [52][53][54][55]. The lipid content ranges from 20 to 80% depending on the various species.…”

In the quest to comply with the Intergovernmental Panel on Climate Change (IPCC) on reducing the global temperature to 1.5-2.0°C as a measure to minimize the climate change caused by the emission of greenhouse gases from the combustion of fossil fuels, and the need for replacement of these fossil fuels, which are also generally believed to be depleting, biodiesel is being studied as a potential replacement for the conventional petroleum diesel. This fuel among other desired properties is renewable, biodegradable, sustainable, and emits less particles. It also contains no amount of sulfur, in addition to possessing most of the good characteristics of petroleum diesel. At the moment, more than 95% of biodiesel produced globally is obtained from vegetable oil feedstocks, which are usually very expensive and thus, without tax waiver and subsidy, makes biodiesel non-competitive with the petroleum diesel. Based on this, non-edible feedstocks are being investigated. Although, their oil yield is low, studies are carried out to ensure efficient extraction. The economics of the process is considered to determine the most economic variables that impact the profitability of biodiesel production. This chapter deals with the biodiesel classification, feedstocks, lipid/oil extraction, biodiesel production methods and the economic aspect of the process.

“…The yield of oil produced by algae is significantly higher (100000 litres/hectare) in comparison to other crops. For example, soybean-446 litres/hectare, sunflower-952 litres/hectare, rapeseed-1200 litres/hectare, caster-1413 litres/hectare, coconut-2689 litres/hectare, and palm-5959 litres/hectare [6]. Their productivity can be enhanced by genetic manipulations making microalgae biodiesel economically competitive with petro diesel through large scale production.…”

Biodiesel is one of the promising alternative fuels for automotive engines due to the depletion of fossil fuel resources, increasing energy demands and environmental concerns. The biodiesel can be obtained from various bio energy resources such as edible and non-edible vegetable oils and animal fats. However, the use of biodiesel derived from edible oils such as palm oil, sunflower oil and soybean oil has negative impact on global food market. Biodiesel from microalgae is considered as a third generation biofuel derived from non-edible resources and best suited for internal combustion engines. Microalgae have the potential to provide sufficient fuel for global consumption due to its high oil content and fast growing ability. This paper provides a brief overview of biodiesel production from microalgae biomass and its suitability as alternate fuel in diesel engines. This review highlights the selection of suitable algae species for oil production, fuel properties in comparison with standard diesel and other biodiesel fuels, performance, combustion and emission characteristics when used in engines, and the economical aspects. Further, the research and development aspects of biodiesel from microalgae as fuel for automobile diesel engines are also reviewed.
