Biofuel production from microalgae has been gaining importance in recent years as an alternative (nonpolluting) fuel source, but the industry faces economic challenges. In this context, a feasible technology of bio-oil production from microalgal biomass through fast pyrolysis is presented in this chapter. A microalga was cultivated in a cheap ethanol-wastewater-based medium, harvested, dried, and subjected to fast pyrolysis, the conditions of which were controlled to generate high yield of bio-oil. Bio-oil yield was 17.4% (m/m), with lower heating value (LHV) of 8,071kcal/kg. Volumetric energetic density was then calculated as 9,927.33kcal/L. Besides bio-oil, coal (10.8% m/m), acid extract (32.3% m/m), and gases (39.5% m/m) were produced. This technology combined low cost and simplicity of operation, turning fast pyrolysis of microalgae into a potential alternative in the free-carbon-emission fuel production process.

Biologically produced fuels are considered potential and viable alternatives to meet the world’s fuel requirements. In this context, algal-based oil is of significant importance due to its renewable and carbon-neutral nature. Biosynthesis of triglycerides by utilizing CO2 (by biofixation) or wastewater under stress conditions via photoautotrophic, heterotrophic (photo/dark), or mixotrophic mechanisms enumerates the potential of microalgae for generation of renewable biodiesel. In addition to the algal cultivation, the conversion of the accumulated lipids to biodiesel is gaining considerable interest. Though there exist some constraints, the process of harnessing biofuel from microalgae is both economically viable and environmentally sustainable compared to the other oil-producing terrestrial crops. This chapter explores biofuel production using microalgae. Concerted efforts are made in this chapter to discuss the biochemistry pertaining to algal lipid synthesis, nutritional modes of algae, cultivation systems used for algal oil production, and the cascade of steps involved, from biomass cultivation to transesterification of the fuel. The ability of microalgae to capture CO2 and its survivability in wastewater is also elaborated in the context of lipid synthesis.

There are several difficulties in developing algal biofuels that can fully replace fossil fuels; the main challenges relate to lower environmental impact (including the possibility of CO2 sequestering and wastewater treatment) and economic feasibility. To date, most studies have focused on selection of species, coupled with optimization of cultivation, biomass harvest and fuel extraction; efforts on enhancing environmental benefits and upgrading spent biomass are thus in order. Industry should indeed adopt an integrated strategy inspired by algal-based biorefineries – toward maximizing the economic return of all products present in algal biomass, by recovering high value compounds prior to biofuel manufacture, and using the remainder for aquaculture/land animal feed and production of other biofuels via supplementary fermentation.

Microalgal biomasses have a long history of industrial production for application in a variety of fields. The success of commercial large-scale production of microalgae depends on many factors, one which is the development of cost-effective systems. Open pond reactors are the most widely used system in large-scale microalgal cultivation due to their low cost of construction, maintenance, and operation. However, closed photobioreactors have a high photosynthetic efficiency and biomass productivity. This study presents the advantages and disadvantages of open ponds compared with other photobioreactors and examines the factors that affect the cultures and their bioproducts.

Algae are currently being considered as a versatile feedstock for biofuel production because of their fast growth rate and high biomass productivity. Algae could simultaneously act as a carbon sink and water purifier if their cultivation were coupled with flue gas and wastewater treatment, respectively. Hence, an understanding of the overall supply chains for algal biofuel production is exceptionally important to determine whether it is worthwhile to scale up and commercialize algal cultivation for biofuel production. In this chapter, various aspects and constraints associated with the commercialization of algal biofuels are deliberated in detail, especially from the perspective of life-cycle energy balance. In addition, discussions on the economic assessments of algal biofuels are included in this chapter to provide an overview of the current state of algal biofuels in the fuel market. Potential algal biofuel conversion technologies, such as transesterification, starch hydrolysis and fermentation, pyrolysis, and hydrothermal liquefaction are also presented.

Extensive effort is being made globally to develop various biofuels as an inexhaustible and renewable energy source. Biofuels are viewed as promising alternatives to conventional fossil fuels because they have the potential to eliminate major environmental problems such as global warming and climate change created by fossil fuels. Among the still-developing biofuel technologies, biodiesel production from algae offers a good prospect for large-scale practical use, considering the fact that algae are capable of producing much more yield than other biofuels such as corn and soybean crops. Although research on algae-based biofuel is still in its developing stage, extensive work on laboratory- and pilot-scale algae-harvesting systems with promising prospects has been reported. This chapter presents a discussion of the literature review of recent advances in algal biomass harvesting. The chapter focuses on stability and separability of algae and algae-harvesting methods. Challenges and prospects of algae harvesting are also outlined. The review aims to provide useful information for future development of efficient and commercially viable algal biodiesel production.
