Natural Mix Algae Possible Source of Renewable Energy, Environmental friendly Bio-hydrogen

Present study is an attempt to explore natural mix algae as a source of bio-hydrogen which is a renewable and environmental friendly clean fuel. Idea is to produce hydrogen in two stages; in first stage algae biomass is grown in light, oxygen and carbon source. In the second stage grown algae produce hydrogen in the absence of light, oxygen and sulfur. Results obtained during study showing that by using natural mix algae hydrogen up to 520 ml/l of algae biomass can be produce in one cycle. However, hydrogen gas can be produced in sufficient quantity up to three cycles. Biological hydrogen production with unicellular mix algae, found to be a promising area of research and conceptual by nature in the laboratory. This process needs to be explored more to prove the ability to use at commercial level. Still much work is required as to make process more economical and practical.
