Written in a lucid style, the book supplies a complete knowledge bank about biohydrogen production processes.

In combating global warming and other environmental issues over the use of fossil fuels, extensive research has been focusing on developing hydrogen production from biological processes. Biohydrogen is considered a promising future biofuel because of its intrinsic clean and high-energy content properties and the way it is produced. In addition to being produced through environmentally friendly biological means, its conversion to energy yields only pure water, which is an ideal energy carrier in reducing greenhouse gas emissions from fossil fuel combustion. Unlike other well-developed biofuels such as bioethanol and biodiesel, biohydrogen production is still in the early stage of development. A variety of technologies are being developed for biohydrogen production. This chapter presents a review of the state-of-the-art and perspectives of bioprocess design for biohydrogen production research in the context of pathways, microorganisms, metabolic flux analysis, process design, and reactor system. Challenges and prospects of biohydrogen production are also outlined.

In this book, the potential biofuel biohydrogen is studied in terms of its generation, applications, and technology. In the first chapter, Caroline V. Rodrigues, Kamili O. Santana, Lorena O. Pires, Michel Brienzo, and Sandra I. Maintinguer provide a theoretical assessment about the biological methods of hydrogen production, as well as examine their applications on research that has been done regarding waste degradation, encouraging sustainable systems for clean energy generation. In the second chapter, Fernando Grijalva-Hern�ndez, Hugo Iv�n Vel�zquez-S�nchez, Juan Carlos Figueroa-Estrada, and Ricardo Aguilar-L�pez present a study where a kinetic model for Hydrogen production by Desulfovibrio bacteria was substantiated using experimental data and used to conduct a local sensitivity analysis. Next, Biniam T. Maru, Magda Constant�, and Francesc Medina evaluate the way in which glycerol may be used to produce biochemical products through dark fermentation, as well as studying its use as a carbon source. Bringing the book to a close, Albanez, R., Lovato, G., Zaiat, M., Ratusznei, S.M., and Rodrigues, J.A.D. parallel AnSBBR that used pure substrates for hydrogen/methane production with AnSBBR that used hydrogen production runoff to produce methane.

Increase in green, renewable and sustainable energy demand due to higher environmental impacts (e.g. Greenhouse gases emissions, climate change, etc.) on consumption of fossil fuel resource put down an extra pressure on government, researchers and industrialists. Among several available biofuel options, biohydrogen is considered as one of the best environmentally clean fuel and a strong candidate to fulfil the future demand of sustainable energy resource. Although, biohydrogen production technology and its use as a fuel is still in infancy stage. Selection of most sustainable production pathway, increase in production upto industrial scale and cost efficiency are some issue still persist with the biohydrogen research. “Biohydrogen Production: Sustainability of Current Technology and Future Perspective” is giving an insight for the sustainable production of biohydrogen at industrial scale.

Bioenergy signifies a sustainable and futuristic alternative to fossil fuels in the realm of growing energy demands, depleting fossil fuel reserves, and increasing pollution loads manifested due to fossil fuel usage. In this context, hydrogen (H2) has gained significant attention as a future energy carrier due to its clean and sustainable nature. Considerable interest has been generated regarding H2 production by biological routes employing photobiological, dark fermentation, thermochemical, enzymatic, etc. Utilizing wastes as a potential source for H2 generation through biological routes has instigated considerable interest and further opening up a new avenue for the utilization of renewable and inexhaustible energy sources. A comprehensive attempt is made through this chapter to compile the contemporary work pertinent to biohydrogen research in unified approach.
