Scientists at the Krizhizhanovski Energy Institute in Moscow have devised a pump system that will help control marine pollution and can be a source of energy. The extraction of hydrogen sulfide at the bottom of the Black Sea by pumps will be economically profitable.
At the bottom of the Black Sea hydrogen sulfide is accumulating, while the gas layer rises two meters a year. 90% of the sea water is contaminated with hydrogen sulfide. The lifeless area starts at 80 meters deep.
A small earthquake can reach the surface of the gas and produce large fires. According to Moscow scientists, tissue pumps installed on the coast will reduce pollution while ethane, ammonia, methane and hydrogen sulfide could be extracted. Gas reserves, estimated at 7.6 billion tons, could reach an extraction quota of about 75 million tons/year.
