Conclusions from First Black Sea Hydrogen Sulfide Workshop (BSHSW): A Review

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

Black Sea, unique in presence of H2S and higher organic carbon levels compare to other seas and oceans, the interest to explore its energy potential. Organic and industrial wastes flowing into the Black Sea is leading to increased H2S thickness year by year impacting sea-life. Several extraction technologies (Land Base Extraction, Off Shore Platform and Subsea Extraction) are possible to remove H2S, while producing hydrogen, chemicals and energy. Main cost driver in the process is extracting H2S through pumping to the surface. Extracted H2S can be utilized through direct burning, using in H2S Fuel Cell (H2S Fuel Cell), electrolyzing, Claus process and wet sulphuric acid processes. Depending on the processes and associated sub-processes, cost of H2S extraction, separation and utilization for energy purposes may or may not have economic value. During extraction and conversion, value added products and processes, i.e. H2, H2SO4, S, CS2, rare earth metals, heavy water, can impact feasibility aspect significantly. Black Sea Hydrogen Sulfide Workshop (BSHSW) has concluded that research in energy, environment and economic aspects of H2S in different countries has to continue and a common platform including Black Sea countries should be formed to organize the actions. Moreover, establishment of a pilot plant to develop and test the proposed technologies is necessary.
