![]() ![]() Accordingly, enormous efforts are directed to transition from fossil fuels to nonpolluting and renewable energy sources. However, the reliance on fossil fuels leads to the significant depletion of natural resources of buried combustible geologic deposits and to negative effects on the global climate with emissions of greenhouse gases. ![]() The current fossil fuel-based generation of energy has led to large-scale industrial development. This review highlights the recent technological progress, enzymes involved and genetic as well as metabolic engineering approaches towards sustainable hydrogen production from microalgae. Several photobioreactors have been developed for large-scale biomass and hydrogen production. ![]() Moreover, biological H 2 production at low operating costs is requisite for economic viability. Manipulation of competing metabolic pathways by modulating the certain key enzymes such as hydrogenase and nitrogenase may enhance the evolution of H 2 from photoautotrophic cells. Progress in genetic/metabolic engineering may significantly enhance the photobiological hydrogen production from microalgae. Advances in hydrogen-fuel-cell technology may attest an eco-friendly way of biofuel production, since, the use of H 2 to generate electricity releases only water as a by-product. Photosynthetic hydrogen production from microalgae can be interesting and promising options for clean energy. Bio-hydrogen from microalgae including cyanobacteria has attracted commercial awareness due to its potential as an alternative, reliable and renewable energy source. ![]()
