  • 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 ...
