“…According to literature reporting [3][4][5], two major classes of hydrogenases are recognized based on their metal active sites: [FeFe] and [NiFe]. Depending on whether light will be involved, this biological hydrogen production process can be simply classified as photo-and dark-fermentation processes [6].…”

“…This reactor consists of algae contained in ponds and this forms the culture. It produces glucose from carbon dioxide, water and several other nutrients [10]. These algae are further passed into a dark anaerobic reactor in order to yield hydrogen and some amount of acetic acid derivative.…”

“…Hydrogenase is extremely sensitive to oxygen and hence the bioreactor used for the process should involve design specifications which are best suited for the required reaction conditions. Indirect biophotolysis [2] Dark fermentation is the fermentative conversion of organic substrate to hydrogen in the absence of a light source [3].…”

Abstract-During the past decade, major studies have identified hydrogen as the safest fuel and its demand has been on the rise ever since. This paper looks into the different biological methods of hydrogen production and the economics involved in-order to identify the most economical and environment friendly method of biohydrogen production. A detailed study has been conducted regarding the methods of production, the types of reactors and raw-materials required. The cost requirement of each of the aspects involved in the processes have been looked into. The study proves the Direct Biophotolysis method to be the least favourable in-terms of land requirement and costs and Indirect Biophotolysis and Photofermentation to be amongst the better options available.

“…Diversity in microbial physiology and metabolism means that there are a variety of different ways in which microorganisms can produce hydrogen, each one with seeming advantages, as well as problematic issues [13]. From an engineering perspective, they all potentially offer the advantages of lower cost catalysts (microbial cells) and less energy intensive reactor operation (mesophilic) than the present industrial process for making hydrogen (steam reformation of methane).…”

“…Thus, in general fermentative systems suffer from low hydrogen yields [19]. The reason for this is that anaerobic metabolism is evolutionarily optimized for maximizing biomass and not hydrogen [13]. Typically, anaerobic species (ex.…”

Dramatically rising oil prices and increasing awareness of the dire environmental consequences of fossil fuel use, including startling effects of climate change, are refocusing attention worldwide on the search for alternative fuels. Hydrogen is poised to become an important future energy carrier. Renewable hydrogen production is pivotal in making it a truly sustainable replacement for fossil fuels, and for realizing its full potential in reducing greenhouse gas emissions. One attractive option is to produce hydrogen through microbial fermentation. This process would use readily available wastes as well as presently unutilized bioresources, including enormous supplies of agricultural and forestry wastes. These potential energy sources are currently not well exploited, and in addition, pose environmental problems. However, fuels are relatively low value products, placing severe constraints on any production process. Therefore, means must be sought to maximize yields and rates of hydrogen production while at the same time minimizing energy and capital inputs to the bioprocess. Here we review the various attributes of the characterized hydrogen producing bacteria as well as the preparation and properties of mixed microfl ora that have been shown to convert various substrates to hydrogen. Factors affecting yields and rates are highlighted and some avenues for increasing these parameters are explored. On the engineering side, we review the potential waste pre-treatment technologies and discuss the relevant bioprocess parameters, possible reactor confi gurations, including emerging technologies, and how engineering design-directed research might provide insight into the exploitation of the signifi cant energy potential of biomass resources.
