Fermentative hydrogen production – An alternative clean energy source

Hydrogen is a valuable gas as a clean energy source and as feedstock for some industries. Therefore, demand on hydrogen production has increased considerably in recent years. Food waste is an important part of urban living garbage,which is full of organic matter and easy to be degraded. So, biological production of hydrogen gas from food waste fermentation has significant advantages for providing inexpensive and clean energy generation to help meet the needs of carbon emission reduction with simultaneous waste treatment. This article reviews the following aspects: mechanism of fermentative hydrogen production by bacteria, and factors influencing fermentative bio-hydrogen production. In addition,the challenges and prospects of bio- hydrogen production are also reviewed.

Clean Energy Source

There was a significant increase in the concern with climate issues, among them highlighted as the derivation of greenhouse gases from the burning fossil fuels, leading several research centers and researchers to seek new sources of less polluting energy, independent of the burn-based matrix of fuels. In this context, the present work has as main presenter a literature review, perspective and comparisons regarding the use of hydrogen as a clean energy source, presenting three main ways of obtaining it: a) through electrolysis using renewable sources; b) biohydrogen production, based on the photosynthesis of plants and algae; c) production through biodigesters.

Fermentative Hydrogen

Biohydrogen is one of the most suitable clean energy sources for sustaining a fossil fuel independent society. The use of both land and ocean bioresources as feedstocks show great potential in maximizing biohydrogen production, but sodium ion is one of the main obstacles in efficient bacterial biohydrogen production.Vibrio tritoniusstrain AM2 can perform efficient hydrogen production with a molar yield of 1.7 mol H2/mol mannitol, which corresponds to 85% theoretical molar yield of H2production, under saline conditions. With a view to maximizing the hydrogen production using marine biomass, it is important to accumulate knowledge on the effects of salts on the hydrogen production kinetics. Here, we show the kinetics in batch hydrogen production ofV. tritoniusstrain AM2 to investigate the response to various NaCl concentrations. The modified Han–Levenspiel model reveals that salt inhibition in hydrogen production usingV. tritoniusstarts precisely at the point where 10.2 g/L of NaCl is added, and is critically inhibited at 46 g/L. NaCl concentration greatly affects the substrate consumption which in turn affects both growth and hydrogen production. The NaCl-dependent behavior of fermentative hydrogen production ofV. tritoniuscompared to that ofEscherichia coliJCM 1649 reveals the marine-adapted fermentative hydrogen production system inV. tritonius.V. tritoniusAM2 is capable of producing hydrogen from seaweed carbohydrate under a wide range of NaCl concentrations (5 to 46 g/L). The optimal salt concentration producing the highest levels of hydrogen, optimal substrate consumption and highest molar hydrogen yield is at 10 g/L NaCl (1.0% (w/v)).

Clean Energy Source

When incubated anaerobically, in the light, in the presence of C2H2 and high concentrations of H2, both Mo-grown Anabaena variabilis and either Mo- or V-grown Anabaena azotica produce large amounts of H2 in addition to the H2 initially added. In contrast, C2H2- reduction is diminished under these conditions. The additional H2-production mainly originates from nitrogenase with the V-enzyme being more effective than the Mo-protein. This enhanced H2-production in the presence of added H2 and C2H2 should be of interest in approaches to commercially exploit solar energy conversion by cyanobacterial photosynthesis for the generation of molecular hydrogen as a clean energy source

Energy Challenge

Sustainable development of the world is mainly dependent on the use of present energy resources, which primarily includes water, wind, solar, geothermal, and nuclear power. Hydrogen as a clean and green energy source can be the resolution of the energy challenge and may satisfy the demands of several upcoming generations. Hydrogen when used it does not produce any type of pollutant and this makes it a best candidate as a clean energy. Hydrogen energy can be generated from natural gas, oil, biomass, and fossil fuels using thermochemical, photocatalytic, microbiological and electrolysis processes. Large scale hydrogen production is also testified up to some extent with proper engineering for multi applications. Alas, storage and transportation of hydrogen are the main challenge amongst scientific community. Photocatalytic hydrogen production with good efficiencies and amount is well discussed. Till date, using a variety of metal oxide-sulfide, carbon-based materials, metal organic frameworks are utilized by doping or with their composites for enhance the hydrogen production. Main intents of this chapter are to introduce all the possible areas of hydrogen applications and main difficulties of hydrogen transportation, storage and achievements in the hydrogen generation with its applications.
