Biohydrogen: For Future Engine Fuel Demands covers the production, purification, storage, pipeline transport, usage, and safety of biohydrogen. Hydrogen promises to be the most significant fuel source of the future, due to its global availability and the fact that water is its only by-product. Biofuels such as bioethanol, biodiesel, bio-oil, and biohydrogen are produced using technologies for thermochemically and biologically converting biomass. Hydrogen fuel production technologies can make use of either non-renewable sources, or renewable sources such as wind, solar, and biorenewable resources. Biohydrogen: For Future Engine Fuel Demands reviews all of the modern biomass-based transportation fuels, including bioethanol, biodiesel, biogas, biohydrogen, and fuel cells. 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.

The world needs clean and renewable energy and hydrogen represents an almost ideal resource. Hydrogen is the simplest and most abundant molecule in the universe, yet one that is a challenge to produce from renewable resources. Biohydrogen, or hydrogen produced from renewable resources such as water or organic wastes by biological means, is a goal worthy of increased global attention and resources. The purpose of BioHydrogen '97 was to bring together leaders in the biological p- duction of hydrogen from the United States, Japan, Europe, and elsewhere to exchange scientific and technical information and catalyze further cooperative programs. Parti- pants came from at least different countries representing academia, industry, and g- ernment. Especially important participants were young research scientists and engineers: the next generation of contributors. The conference consisted of plenary presentations, topical sessions, posters, and mini-workshop discussions on key areas of biohydrogen. It was designed to maximize - formation exchange, personal interaction among participants, and formulate new inter- tional initiatives. BioHydrogen '97 was an outgrowth of an international workshop convened by the Research Institute of Innovative Technology for the Earth (RITE) and was held in Tokyo, Japan, November 24-25, 1994. The RITE workshop was highly successful but largely l- ited to traditional biochemical and biological studies and not engineering research topics.

Extensive researches in the past have shown substantial improvement and development in both the yield and the volumetric production rates of biohydrogen. Yet, for commercial-scale applications that are cost-effective, biohydrogen yields and production rates must outdo significantly the existing accomplishments. Until now, there have been no reports of a commercial-scale biohydrogen production system in the world. This chapter deals with technoeconomic evaluation, fundaments of scale-up, and pilot-scale studies to help in the setup of a commercial-scale system. The scale-up process with the key component of kinetics and hydrodynamics of a fermenter is further supported by data mining of reported pilot-scale systems.

Highlights: A mixed culture and C. butyricum were used to ferment dried and ground S. obliquus biomass. The best adapted mixed culture LE37 produces 1.52 mol H2 /mol from 50 g/L of dried and ground S. obliquus . C. butyricum produces 116.3 mL H2 /g alga vs, attaining a H2 yield of 2.74 mol/mol. The biogas produced by C. butyricum has the highest purity, H2 /CO2 (v/v) of 1.7. Abstract: Scenedesmus obliquus biomass was used as a feedstock for comparing the biological production of hydrogen by two different types of anaerobic cultures: a heat-treated mixed culture from a wastewater treatment plant and Clostridium butyricum DSM 10702. The influence of the incubation temperature and the carbon source composition were evaluated in order to select the best production profile according to the characteristics of the microalgal biomass. C. butyricum showed a clear preference for monomeric sugars and starch, the latter being the major storage compound in microalgae. The highest H2 production reached by this strain from starch was 468 mL/g, whereas the mixed culture incubated at 37 °C (LE37) produced 241 mL/g. When the mixed culture was incubated at 58 °C (LE58), a significant increase in the H2 production occurred when xylose and xylan were used as carbon and energy source. The highest H2 yield reached by the LE37 culture or in co-culture with C. butyricum was 1.52 and 2.01 mol/mol of glucose equivalents, respectively. However, the ratio H2 /CO2 (v/v) of the biogas produced in both cases was always lower than the one produced by the pure strain. In kinetic assays, C. butyricum attained 153.9 mL H2 /L h from S. obliquus biomass within the first 24 h of incubation, with a H2 yield of 2.74 mol/mol of glucose equivalents. H2 production was accompanied mainly by acetate and butyrate as co-products. In summary, C. butyricum demonstrated a clear supremacy for third generation bioH2 production from S. obliquus biomass.

Biohydrogen Production: Fundamentals and Technology Advances covers the fundamentals of biohydrogen production technology, including microbiology, biochemistry, feedstock requirements, and molecular biology of the biological hydrogen production processes. 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. The book summarizes research advances that have been made in this field and discusses bottlenecks of the various processes, which presently limit the commercialization of this technology. The authors also focus on the process economy, policy, and environmental impact of this technology, since the future of biohydrogen production depends not only on research advances, but also on economic considerations (the cost of fossil fuels), social espousal, and the development of H2 energy systems. The book describes the fundamentals of this technology interwoven with more advanced research findings. Further reading is suggested at the end of each chapter. Since the beauty of any innovation is its applicability, socioeconomic impact, and cost energy analysis, the book examines each of these points to give you a holistic picture of this technology. Illustrative diagrams, flow charts, and comprehensive tables detailing the scientific advancements provide an opportunity to understand the process comprehensively and meticulously. Written in a lucid style, the book supplies a complete knowledge bank about biohydrogen production processes.

The purpose of this study was to determine Clostridium termitidis microbial kinetics on glucose, cellobiose, and cellulose, and to assess its co-culture with Clostridium beijerinckii for hydrogen production. Microbial kinetics parameters of the mesophilic, cellulolytic, and hydrogen producer C. termitidis were determined on glucose and cellobiose using MATLAB for modelling biomass growth and substrate consumption. Hydrogen yields on these substrates were 1.99 and 1.11 mol H2 mol-1 hexose equivalent, respectively. C. termitidis microbial kinetics in mono-culture and in co-culture with mesophilic hydrogen producer C. beijerinckii were also investigated under agitated and non-agitated conditions, with hydrogen yields of 1.46 and 2.11 mol H2 mol-1 hexose equivalentadded for agitated mono-culture and co-culture, respectively, as compared with 1.45 and 1.92 mol H2 mol-1 hexose equivalentadded in unagitated cultures. Soluble metabolites were also included in the mathematical model. Moreover, co-culturing of C. termitidis and C. beijerinckii on cellulose was proven to enhance hydrogen production directly from a complex substrate like cellulose under mesophilic conditions.
