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 of microalgae culture is provided. The book is intended for the expert and those starting work in the field.​

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.

Algae Energy covers the production of algae culture and the usage of algal biomass conversion products. It also reviews modern biomass-based transportation fuels, including biodiesel, bio-oil, biomethane and biohydrogen. Each chapter opens with fundamental explanations suitable for those with a general interest in algae energy and goes on to provide in-depth scientific details for more expert readers. Algae energy is discussed within the wider context of green energy, with chapters covering topics such as: green energy facilities, algae technology, energy from algae and biodiesel from algae. Algae Energy addresses the needs of energy researchers, chemical engineers, fuel and environmental engineers, postgraduate and advanced undergraduate students, and others interested in a practical tool for pursuing their interest in bio-energy.

Handbook of Algal Biofuels: Aspects of Cultivation, Conversion and Biorefinery comprehensively covers the cultivation, harvesting, conversion, and utilization of microalgae and seaweeds for different kinds of biofuels. The book addresses four main topics in the algal biofuel value-chain. First, it explores algal diversity and composition, covering micro- and macroalgal diversity, classification, and composition, their cultivation, biotechnological applications, current use within industry for biofuels and value-added products, and their application in CO2 sequestration, wastewater treatment, and water desalination. Next, the book addresses algal biofuel production, presenting detailed guidelines and protocols for different production routes of biodiesel, biogas, bioethanol, biobutanol, biohydrogen, jet fuel, and thermochemical conversation methods. Then, the authors discuss integrated approaches for enhanced biofuel production. This includes updates on the recent advances, breakthroughs, and challenges of algal biomass utilization as a feedstock for alternative biofuels, process intensification techniques, life cycle analysis, and integrated approaches such as wastewater treatment with CO2 sequestration using cost-effective and eco-friendly techniques. In addition, different routes for waste recycling for enhanced biofuel production are discussed alongside economic analyses. Finally, this book presents case studies for algal biomass and biofuel production including BIQ algae house, Renewable Energy Laboratory project, Aquatic Species Program, and the current status of algal industry for biofuel production. Handbook of Algal Biofuels offers an all-in-one resource for researchers, graduate students, and industry professionals working in the areas of biofuels and phycology and will be of interest to engineers working in renewable energy, bioenergy, alternative fuels, biotechnology, and chemical engineering. Furthermore, this book includes structured foundational content on algae and algal biofuels for undergraduate and graduate students working in biology and life sciences. Provides complete coverage of the biofuel production process, from cultivation to biorefinery Includes a detailed discussion of process intensification, lifecycle analysis and biofuel byproducts Describes key aspects of algal diversity and composition, including their cultivation, harvesting and advantages over conventional biomass

Microalgae-Based Biofuels and Bioproducts: From Feedstock Cultivation to End Products compiles contributions from authors from different areas and backgrounds who explore the cultivation and utilization of microalgae biomass for sustainable fuels and chemicals. With a strong focus in emerging industrial and large scale applications, the book summarizes the new achievements in recent years in this field by critically evaluating developments in the field of algal biotechnology, whilst taking into account sustainability issues and techno-economic parameters. It includes information on microalgae cultivation, harvesting, and conversion processes for the production of liquid and gaseous biofuels, such as biogas, bioethanol, biodiesel and biohydrogen. Microalgae biorefinery and biotechnology applications, including for pharmaceuticals, its use as food and feed, and value added bioproducts are also covered. This book’s comprehensive scope makes it an ideal reference for both early stage and consolidated researchers, engineers and graduate students in the algal field, especially in energy, chemical and environmental engineering, biotechnology, biology and agriculture. Presents the most current information on the uses and untapped potential of microalgae in the production of bio-based fuels and chemicals Critically reviews the state-of-the-art feedstock cultivation of biofuels and bioproducts mass production from microalgae, including intermediate stages, such as harvesting and extraction of specific compounds Includes topics in economics and sustainability of large-scale microalgae cultivation and conversion technologies

Biofuels made from algae are gaining attention as a domestic source of renewable fuel. However, with current technologies, scaling up production of algal biofuels to meet even 5 percent of U.S. transportation fuel needs could create unsustainable demands for energy, water, and nutrient resources. Continued research and development could yield innovations to address these challenges, but determining if algal biofuel is a viable fuel alternative will involve comparing the environmental, economic and social impacts of algal biofuel production and use to those associated with petroleum-based fuels and other fuel sources. Sustainable Development of Algal Biofuels was produced at the request of the U.S. Department of Energy.

Microalgae Cultivation for Biofuels Production explores the technological opportunities and challenges involved in producing economically competitive algal-derived biofuel. The book discusses efficient methods for cultivation, improvement of harvesting and lipid extraction techniques, optimization of conversion/production processes of fuels and co-products, the integration of microalgae biorefineries to several industries, environmental resilience by microalgae, and a techno-economic and lifecycle analysis of the production chain to gain maximum benefits from microalgae biorefineries. Provides an overview of the whole production chain of microalgal biofuels and other bioproducts Presents an analysis of the economic and sustainability aspects of the production chain Examines the integration of microalgae biorefineries into several industries
