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.
It also gives insight into scale-up problems and limitations. In addition, the book discusses mathematical modeling of the various processes involved in biohydrogen production and the software required to model the processes.
With 50% more content, this new edition outlines the scaling of processes and features material from experienced international researchers working at the interface of biotechnology and engineering.
This book will provide a platform for motivation of researchers and industrialists for innovative ideas and thoughts to bring biohydrogen production at industrial scale.
The book also discusses issues of biohydrogen economy, policy and environmental impact. Biohydrogen looks set to be the fuel of choice in the future, replacing both fossil fuels and biorenewable liquid fuels.
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.
Covering several advanced waste-to-biohydrogen pretreatment and production processes, this book investigates the future trends and the promising pathways for biohydrogen production from waste.
Strategies for improving microalgae biohydrogen production and factors to be considered for scaling-up the process are also outlined in this chapter.
ABSTRACT Hydrogen produced by microalgae and bacteria is biohydrogen. There are currently no practical biohydrogen production processes. However, several concepts have promise for near- to long-term process development.
