“…The result is sustained H 2 production via direct photolysis. The technique was pioneered using microalgae (Benemann 1996;Jo et al 2006;Laurinavichene et al 2006) and has been recently extended to cyanobacteria (Antal & Lindblad 2005). …”

Biological methods of hydrogen production are preferable to chemical methods because of the possibility to use sunlight, CO 2 and organic wastes as substrates for environmentally benign conversions, under moderate conditions. By combining different microorganisms with different capabilities, the individual strengths of each may be exploited and their weaknesses overcome. Mechanisms of bio-hydrogen production are described and strategies for their integration are discussed. Dual systems can be divided broadly into wholly light-driven systems (with microalgae/cyanobacteria as the 1 st stage) and partially light-driven systems (with a dark, fermentative initial reaction). Review and evaluation of published data suggests that the latter type of system holds greater promise for industrial application. This is because the calculated land area required for a wholly light-driven dual system would be too large for either centralised (macro-) or decentralised (micro-)energy generation. The potential contribution to the hydrogen economy of partially light-driven dual systems is overviewed alongside that of other bio-fuels such as bio-methane and bio-ethanol.Redwood et al. -Dual systems for Bio-H 2 -Reviews in Environ.

“…Benemann estimated that hydrogen production from wastewater has the greatest potential for economical near-term production of hydrogen from renewable resources-but only if hydrogen conversion efficiency could be increased to 60-80% (14). However, substantial technical barriers must be overcome to achieve such efficiency.…”

“…It has been argued that in order for hydrogen production by dark fermentation to be economically feasible and sustainable, a two-step/hybrid biological hydrogen production process would be necessary [25]. By combining the anaerobic and photosynthetic steps, as shown in Fig.…”

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.
