Hydrogen Sulfide Energy of the Black Sea

Abstract

The word combination “hydrogen sulfide energy” was implemented after a series of publications dedicated to solving the problem of obtaining the energy from hydrogen sulfide of the Black Sea. This direction of research is a part of area of expertise which recently has been intensively developing – hydrogen sulfide energy. It is known that there is no hydrogen sulfide in the Black Sea in a thin surface layer with thickness 100 - 150 m, with a maximum depth of the basin about two kilometers. Starting from the depths of 100-150 m the concentration of hydrogen sulfide is increasing and reaches the value of ~ 10 mg/l at the bottom of the sea. Extraction of the hydrogen sulfide accumulated in waters of the Black Sea is a serious problem. Therefore, at present, a big number of technologies were offered to obtain hydrogen sulfide from waters of the Black Sea. All of them are resource and energy-consuming. The most preferable one, according to the stated parameters, is the hydrogen sulfide gas-lift technology of delivering water at a certain height above the sea level, its decontamination due to fast decompression, and ubsequent discharge to a depth where the concentration of hydrogen sulfide corresponds to its concentration in the discharged water. Ecological risks appear when implementing such a technology, which may be leveled by conducting of special activities. Hence, implementation of gas-lift technology provides delivery of big volumes of deep sea waters at the level higher than the sea level, there is a possibility of additional obtaining of energy due to differences in temperatures, salinity of surface and deep waters, as well as hydrostatic power of water lifted at certain level above the sea level. If such energy generating facility can be constructed on the bases of floating platform, then there is a possibility to increase the generating capacity of the complex using energy of waves, wind and the sun. Thus, this paper provides the possibility of creating a floating power generating facility for extraction of different types of energies that are concentrated in the Black Sea.
