Abstract: Recently, several types of biofuels have been investigated as renewable and cleaner alternatives to fossil fuels. Biohydrogen is the only carbon-free fuel which ultimately produces water via combustion. It can be considered a potential contender for future fuels, due to its unique properties like high energy content, and renewability. Biohydrogen production and storage is a fascinating, yet challenging task. This review focuses on the effect of various nanomaterials additives on the biohydrogen production rate and storage, as the two most important challenges. These nanomaterials are classified into two classes: Inorganic nanoparticles, and organic nanoparticles. Inorganic nanoparticles promote bio-hydrogen production during the dark fermentation process and light photosynthesis because of their positive effect on nitrogenases and hydrogenases activities, at specific concentrations and sizes. The physical and chemical properties of nanoparticles play a role in their efficiency. The organic nanoparticles and nanomembranes can be used in the purification and storage of biohydrogen.

Keywords: biohydrogen; nanoparticles; nanocatalysts; bio photolysis; microbial water-gas shift; photo fermentation; dark fermentation; MECs; microbial electrolysis cells.
