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

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 (

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

Microalgae are one of the most studied potential sources of biofuels and bioenergy. This book covers the key steps in the production of renewable biofuels from microalgae - strain selection, culture systems, inorganic carbon utilisation, lipid metabolism and quality, hydrogen production, genetic engineering, biomass harvesting, extraction. Greenhouse gas and techno-economic modelling are reviewed as is the 100 year history of microalgae as sources of biofuels and of commercial-scale microalgae culture. A summary of relevant basic standard methods used in the study

Fossil-fuel depletion and attempts at global-warming mitigation have motivated the development of biofuels. Several feedstock and transformation pathways into biofuel have been proposed as an alternative to the usual fuels. Recently, microalgae have attracted a good deal of attention because of the promise of reduced competition with food crops and lowered environmental impacts. Over the last years, several life-cycle assessments (LCAs) have been realized to evaluate the energy benefit and potential global-warming reduction of biofuel and bioenergy produced from microalgae.

Energy security, increasing oil prices, fossil resource depletion, and climate change are some of the greatest challenges faced by mankind at present. Third-generation biofuel feedstock and micro-and macroalgae have many advantages over the first and second generations of biofuels. In addition, defatted algae can also be used as a feedstock for production of hydrocarbons. Thermochemical methods are more efficient than any other routes for conversion of algae. Among thermochemical methods, hydrothermal upgradation is the most promising because it can process

Algae presents a viable biofuel alternative because the production of algae for fuel, unlike other agro-based biofuels, does not compete with food production. This book covers algae-based biofuel options and discusses the design and economic viability of algal bioenergy co-production concepts.

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

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

With increased energy demand, diminished fossil fuel reserves, elevated concerns over the impacts of increasing CO2 on climate change, and unpredictable foreign suppliers, the development of sustainable and renewable fuels has become a top priority. Microalgae are photosynthetic organisms that are able to convert sunlight, CO2, and water into organic matter and therefore possess great potential as a renewable feedstock for biofuels. During the past few years, there has been tremendous interest in using metabolic engineering and biotechnology approaches to
