Hydrogen Production Using Photobiological Methods

Production of photobiological hydrogen by microorganisms has been an active field of research for many years. The experimental process for generating photobiological hydrogen from water using solar energy has become a major novel source of sustainable and renewable production of hydrogen gas without greenhouse gases emissions or environmental pollutants. Hence, this method is considered a future alternative source of energy. Several methods have been developed to generate hydrogen gas; among them, the generation of photobiological hydrogen is one of the most important and easy methods. In addition, photobiological methods easily achieve the efficiency of solar energy conversion, which may be economically feasible in the future. As we know, several microorganisms such as algae, cyanobacteria, bacteria, and even higher plants have the capacity to produce biohydrogen in the presence of sunlight. Hence, based on current and previous research, we briefly review the different strategies for renewable photobiological and artificial hydrogen production as well as its significance for a multidisciplinary approach.
