HYDROGEN - ENERGY FOR BULGARIA

The purpose of this work is to identify and present the opportunities for Bulgaria to use hydrogen as an energy source. Today's primary energy sources are mostly non-renewable - coal, oil, natural gas and conventional sources of nuclear energy. There are also renewable sources such as falling water, solar radiation, plants, manure, wind and geothermal sources. Theoretically, all types of energy sources can be used in Bulgaria, but each has its advantages and disadvantages or risks in terms of human health impact, of environmental and economic perspective. Still many governmental bodies and some of the scientific community underestimated the threat to the ozone layer caused by combustion processes and emissions from thermal power plants (TPPs) and transport. The problem of global warming and the preservation of the ozone layer will encourage Bulgaria to focus efforts and resources for using hydrogen as an energy source. The Black Sea is the world's largest body of water containing H2S and hydrogen sulfide layer that begins about 200 meters below the surface. The total supply of hydrogen sulfide in the Black Sea is estimated at about 4.6 x 109 tons. Interest in that reserve is manifested by the countries around the Sea - Turkey, Ukraine, Romania, Russia, Bulgaria and Georgia. Methods for extracting hydrogen from hydrogen sulfide are in development. There are concerns that the increase of hydrogen sulfide in the Black Sea may cause huge environmental disaster that can be countered by its reduction and use.
