Photobiological hydrogen as a renewable fuel

The huge global energy consumption has raised concerns over the depletion in readily available conventional resources. Besides, there are harmful atmospheric effects of fossil fuels and qualms future world hence is dire need new renewable sources that cheap, non-polluting, environmentally friendly, clean. This only way we can stop using fossil. Hydrogen considered as an ideal fuel for because its high content clean combustion to water. However, extensive technologies required introduce hydrogen alternative cost-effective fuel, which brings about relevance exploitation microorganisms large-scale production. Reports photobiological production by oxygenic photosynthetic microbes, such green algae cyanobacteria anaerobic photosynthesis, summarized this paper, with a focus on major obstacles must be overcome scientific technical breakthroughs make commercially feasible energy. principle, progress, prognosis source reviewed.
