Biohydrogen is a promising gaseous biofuel that has prospective applications in combined heat and power, for fuel cells, or as a precursor for chemicals production. Hydrogen can also be converted to liquid hydrocarbon fuels and value-added chemicals through catalytic thermochemical or through biocatalytic biological pathways. This book addresses both the fundamentals as well as advanced new technological research on biohydrogen production by focusing on recent global research with emphasis on the technological, environmental, socioeconomic, and techno-economic aspects. It covers some the important advances in the production and utilization of biohydrogen and its solutions for clean fuel, waste management, waste valorization, reduced greenhouse gas emissions, and climate change mitigation. The book first covers the basic principles, benefits, and challenges concerning both the biological and thermochemical routes for biohydrogen production and then goes on to address topics such as biomass conversion to hydrogen through gasification with a focus on the process parameters, catalytic reforming technologies for hydrogen production concerning various feedstocks, the co-conversion of plastic wastes and biomass into biohydrogen through co-gasification technology, the effect of process parameters on syngas yields through co-gasification; fermentative hydrogen production technologies, the molecular mechanism of hydrogen production and enhancing the yield in hydrogen production by genetic and metabolic engineering, hydrogen production routes through microbial electrolysis, and much more.

Among energy sources, hydrogen gas is clean and renewable and has the potential to solve the growing energy crisis in today's society because of its high-energy density and noncarbon fuel properties. It is also used for many potential applications in nonpolluting vehicles, fuel cells, home heating systems, and aircraft. In addition, using hydrogen as an energy carrier is a long-term option to reduce carbon dioxide emissions worldwide by obtaining high-value hydrocarbons through the hydrogenation of carbon dioxide. This book presents the recent progresses and developments in water-splitting processes as well as other hydrogen generation technologies with challenges and future perspectives from the point of energy sustainability.

Hydrogen economy represents the future of human civilization. Limited resources of our planet are compelling us to turn to renewable clean energy resources and hydrogen figures prominently as the energy carrier of a future sustainable energy system. There are significant challenges to be overcome in order to make hydrogen viable, in production, storage and power generation, while safety of operation is an ever-present factor that determines success or failure of a proposed solution. Recent developments in all of these aspects are reviewed in this book, along with some latest research in the field of hydrogen energy and use.

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.
