The article deals with current issues of energy diplomacy of Turkey. The authors describe the main positive and negative results of Turkey's foreign energy policy in terms of the implementation of major energy projects. Geopolitical processes in the world, the conflict of interests of various countries in the political arena are important factors that affect the crude oil and natural gas pipeline projects. Particular attention is paid to the problems and prospects of cooperation between the Turkish Republic and the Russian Federation in the fuel and energy complex. The authors describe the interaction betweeen Russia and Turkey in the energy sector, including geo-economic interests of the countries in the Russian-Turkish gas dialogue. Turkey made efforts to position as an alternative gas supply route, taking advantage of concern about increasing Europe's dependence on Russian exports. Last years Turkey has set itself the important task - to turn from transit country into a regional gas hub. Ukrainian crisis increased the geostrategic importance of the Black Sea region to Russia, as well as strengthened the ambition of the Turkish side. The authors also highlight the prospects of the natural gas pipeline project from Russia via the Black Sea to Turkey and to the Turkish-Greek border, which named "Turkish stream". This project was frozen in terms of military and political processes at the end of 2015 in Syria.

The article discusses a promising energy-technology unit for the extraction of hydrogen sulfide from the deep waters of the Black Sea, which provides for raising the gas-liquid mixture from the depths by the gas-lift method using wave pulses to separate hydrogen sulfide in the gaseous state. The installation includes a supply line, which is lowered to the required depth, a supply pump, a coalescing separator, a seawater discharge line with a reduced concentration of hydrogen sulfide, a control valve, a hydrodynamic generator of mechanical vibrations, a lifting pipeline, a high pressure hydrogen sulfide separator, a hydraulic turbine, a low pressure hydrogen sulfide separator, seawater discharge pipe and hydrogen sulfide expander. This unit will improve the energy efficiency and operational reliability of the process of hydrogen sulfide production, as well as reduce the burden on the Black Sea environment. A mathematical model of this setup has been developed. The results obtained by the mathematical model adequately coincide with the known experimental ones. This suggests that it is possible to use the model to determine the parameters of the process for the extraction of hydrogen sulfide from the Black Sea. The parameters of the process for the extraction of hydrogen sulfide from the Black Sea in the depth range of the pipeline 0...1000 m at a temperature of 280...285 K. It has been established that increasing the gas content of seawater from 0 to 2.5 m3/m3 leads to a decrease in the pressure value by 2.2 MPa. A further increase in seawater gas content from 2.5 to 5.0 m3/m3 is accompanied by a decrease in pressure of another 1.6 MPa. Such a significant decrease in pressure at the inlet to the riser piping allows hydrogen sulfide and seawater to be obtained at a pressure that is substantially greater than atmospheric. The excess pressure at the outlet of the lifting pipeline is determined based on data obtained by the method of "equivalent length". When the seawater gas content is 2.5 m3/m3, the pipeline’s immersion depth is 250...1000 m, the value of the overpressure of substances at the exit of the lifting pipeline will be 0.2...0.45 MPa, and at 5 m3/m3 – 0.67...1.07 MPa, at 7.5 m3/m3 – 0.83...1.4 MPa and at 10 m3/m3 – 0.97...1.68 MPa.

TurkStream will need Russian gas discount deal

Subject The Russo-Turkish intergovernmental TurkStream agreement. Significance An agreement signed by Russian President Vladimir Putin and his Turkish counterpart Recep Tayyip Erdogan on October 10 envisages a 31.5-billion-cubic-metres/year (bcm/y) natural gas transit line under the Black Sea and through Turkey to the Turkish-Greek border. One of two parallel pipes would supply 15.75 bcm/y gas to Turkey, replacing an existing pipeline. The second would export the same volume to European markets via a planned border 'hub' and export route yet to be announced. Impacts TurkStream's extra volume will increase Turkish dependence on Russian gas but allow more supply flexibility during peak winter demand. Delivering more Russian gas to Central-Eastern Europe will make it more difficult for other potential gas suppliers to secure market share. The agreement will bring Ankara and Moscow closer and may be followed by a new deal to restart the frozen Akkuyu nuclear plant.

Subject The decision to restart the TurkStream natural gas pipeline from Russia to Turkey. Significance The agreement on August 9 between Russian and Turkish Presidents Vladimir Putin and Recep Tayyip Erdogan to resume the TurkStream project relaunches their partnership in the energy sector. This had been frozen as a result of Turkey's shooting down of Russian Su-24 jet last November. Impacts Turkey could start importing up to 15.75 bcm additional natural gas under the Black Sea by 2019. Such a reduced amount compared with the original plan would seem to allow room in the Turkish gas market for rival suppliers. TurkStream could be extended into the EU only if the European Commission and Gazprom compromise on third-party access to the pipeline.
