Energy Resources of the Black Sea Shelf

Energy resources of the Black Sea shelf cover hydrocarbon deposits (natural gas and oil), giant deposits of methane gas hydrates, as well as the hydrogen sulfide potential of the deepwater zone of the Black Sea. Development of this potential is a defining factor in geopolitics, energy independence of Ukraine, and meeting domestic fuel needs without import dependency.

Overview

The hydrocarbon potential of the offshore shelf is a strategic direction for energy development after the depletion of onshore fields, similar to the development of the North Sea by European countries since the 1960s. Development of the Black Sea shelf requires substantial capital investment (hundreds of billions of dollars) and is highly sensitive to fluctuations in global oil and gas prices: during periods of high prices, investor interest grows, while during slumps, project initiatives are frozen.

In the 1990s, falling global oil prices put an end to attempts by Yuriy Meshkov's government to attract British Petroleum to develop Crimea's shelf, and subsequently led to the default of the rf economy in 1998. Ukraine invested over 12 billion hryvnias into the state company Chornomornaftohaz, creating offshore extraction infrastructure.

In 2014, the russian federation occupied the Crimean Peninsula and unlawfully seized the extraction infrastructure of Chornomornaftohaz. The Kremlin regime's primary goal was not so much its own development of the fields, but preventing Ukraine's energy independence and blocking the emergence of Ukrainian gas on the European market (specifically in Poland).

In addition to traditional hydrocarbons, the Black Sea possesses colossal deposits of inexhaustible and alternative energy sources — methane gas hydrates (the largest in Europe) and hydrogen sulfide, the decomposition and processing of which serve as a resource for hydrogen energy and the chemical industry.

Key Details / Subtopics

  • Hydrocarbon shelf and Chornomornaftohaz:
  • Ukraine invested 12 billion UAH into developing the technical base and drilling rigs of JSC Chornomornaftohaz.
  • Annual gas extraction on the shelf under occupational control after 2014 stands at around 2 billion m³. A significant part of extraction occurs at so-called "Odesa" offshore fields, which have no connection to the Crimean Peninsula and represent direct theft of Ukrainian resources.

  • Full-scale extraction on the Black Sea and Sea of Azov shelves is capable of completely covering Ukraine's domestic needs, allowing a transition away from coal, reducing load on nuclear power, and exporting gas to Poland (where import needs grew from 10 billion m³ to 12 billion m³ in 2020).

  • rf seizure of infrastructure (2014) and geopolitical dimension:

  • Net profit loss of Gazprom (a 3.3-fold reduction in 2014) due to the start of the shale revolution and devaluation of the Shtokman field in the Barents Sea forced the Kremlin to deploy military aggression.

  • In 2014, russia's initial strikes were directed at Crimea (main part of the shelf), Sloviansk (shale gas), and Mariupol (control of the Sea of Azov) to block competition to russian monopolies.

  • Methane gas hydrates in the Black Sea:

  • Solid compounds of methane and water existing under high pressure and low temperatures. One cubic meter of hydrate releases 164 m³ of natural gas.
  • Ukraine possesses the largest deposits of methane gas hydrates in Europe, estimated at 60–70 trillion m³.
  • From the late 1980s, development of the topic was led by the Odesa Academy of Refrigeration. The innovative project "Methane from Gas Hydrates of the Black Sea" envisaged creating the first extraction complex with a capacity of 1,680 tons of liquid methane per day ($150 million investment with a 2-year payback; overall industry deployment was estimated at $480 billion).

  • Active participation in research was taken by the Sevastopol Institute of the Biology of the Southern Seas, and starting in 2010 joint German-Ukrainian exploration expeditions were conducted. The process was halted by russian occupation.

  • Black Sea hydrogen sulfide and hydrogen energy:

  • Deepwater layers of the Black Sea contain about 30 billion tons of hydrogen sulfide ($H_2S$), which is a renewable resource (4–9 million tons naturally generated annually).
  • Component yield potential: 28 billion tons of sulfur (raw material for sulfuric acid and oleum; global market 70 million tons worth $9–10 billion) and 2 billion tons of hydrogen.
  • Hydrogen has the highest specific heat of combustion and flame temperature (2800 °C), releasing only water vapor upon combustion. Promising applications include using hydrogen at stationary facilities (CHPPs) and in fuel cells for motor transport for direct electricity generation without thermal emissions.

Contradictions and Open Questions

  • Technological and ecological challenges of hydrate and hydrogen development:
  • Raising gas hydrates from the seabed requires maintaining pressure and temperature, as they decompose when heated. The rf lacks relevant technologies, and Gazprom is not interested in developing alternative extraction.
  • Mass release of water vapor from hydrogen combustion creates a powerful greenhouse effect (an order of magnitude stronger than $CO_2$), making fuel cells and closed-cycle CHPPs a priority.
