Abstract
    This review article explores the potential of using mariculture-raised cyanobacteria as solar energy converters of hydrogen (H2). The exploitation of the sea surface for large-scale renewable energy production and the reasons for selecting the economical, nitrogenase-based systems of cyanobacteria for H2 production, are described in terms of societal benefits. Reports of cyanobacterial photobiological H2 production are summarized with respect to specific activity, efficiency of solar energy conversion, and maximum H2 concentration attainable. The need for further improvements in biological parameters such as low-light saturation properties, sustainability of H2 production, and so forth, and the means to overcome these difficulties through the identification of promising wild-type strains followed by optimization of the selected strains using genetic engineering are also discussed. Finally, a possible mechanism for the development of economical large-scale mariculture operations in conjunction with international cooperation and social acceptance is outlined.
