The possibilities for hydrogen production from H2S and storage in the Black Sea
The Black Sea, a highly isolated inland sea, is the largest anoxic zone in the world. Since the hydrogen sulphide (H2S) zone was discovered in the early 19th century in the Black Sea, it has been accepted that there is no life in the depths of the Black Sea and only bacteria live in the H2S layer. A high content of organic matter, with maximum processes of bacterial sulphate reduction, is the major source of this H2S zone. H2S is one of the most poisonous gases in the world, but it has great economic value to obtain hydrogen via dissociation into hydrogen and sulphur. Thus, the Black Sea not only has a serious environmental contamination, but is also a potential source of hydrogen energy if a decomposition process can be developed. In this study, a proposal is made for the production of hydrogen from hydrogen sulphate to be extracted from the waters of the Black Sea and storage by the natural sources of the Black Sea.
