Arctic politics: Europe enters the game, Norway at its side

The Barents Sea, off the coast of Norway, is gaining weight in the EU’s energy strategy.

Over the past three years, natural gas has returned to the centre of continental geopolitics. The most intense phase of the Russia-Ukraine war and the global scramble for LNG made one thing clear: energy is not just a commodity. It is political leverage, economic power and geopolitical influence.

Brussels is now revisiting its Arctic policy, taking a harder look at the Barents. The area — part of the Arctic Ocean north of Norway and Russia — faces the Kola Peninsula, home to Russia’s Northern Fleet, including its nuclear submarines.

The environmental dimension is only part of the story. The stakes are strategic. 

According to the U.S. Geological Survey, the Arctic may hold around 30% of the world’s undiscovered natural gas and 13% of its undiscovered oil.

From pipelines to LNG

Gas remains a key component of Europe’s energy mix.

After Russia’s invasion of Ukraine, the EU accelerated supply diversification, replacing much of its pipeline gas with LNG, primarily from the United States and Qatar. 

Under the REPowerEU plan, the Commission aims to end all imports of Russian gas — both pipeline and liquefied — by November 2027.

The move avoided an energy collapse. But it increased exposure to global markets, spot prices and Asian competition.

In short, Europe is now more dependent on the sea and less on land infrastructure, with direct geopolitical consequences.

Norway steps forward 

Norway is today the EU’s largest gas supplier. An increasing share comes from the Barents, where fields such as Johan Castberg are strengthening Oslo’s role in Europe’s energy system.

Development timelines, however, are long. Five to ten years can pass between discovery and stable production. 

Decisions taken now will determine whether, by 2035, Europe can rely on higher Norwegian volumes — or remain structurally dependent on the global LNG market.

Fragile infrastructure 

Strategic value comes with technical risk.

Subsea infrastructure linking the Barents to European markets, including pipelines and facilities such as Snøhvit, operates in extreme conditions, at depths between 2,000 and 3,000 metres. 

Moving ice, strong currents and seabed instability increase mechanical stress and erosion risks.

Maintenance costs can run up to 50 percent higher than in areas such as the Mediterranean. In the event of an accident or sabotage, repairs could take months, with immediate effects on European gas prices.

Physical vulnerabilities are compounded by digital ones. Industrial control systems managing pipelines and facilities face hybrid threats in a region shaped by Russia-NATO tensions. 

Cyberattacks, ransomware and legacy protocol weaknesses pose concrete risks.

The EU has strengthened its regulatory framework through the NIS2 Directive. But cooperation with Norway remains decisive.

A fault line in the North

This year, Oslo is expected to supply around 120 billion cubic metres of gas to the EU, with a growing share from the Barents. Any significant disruption could push up the TTF benchmark and force greater reliance on US or Qatari LNG.

In the short term, the risk appears manageable thanks to investment in physical and digital protection, stronger European coordination and enhanced Arctic surveillance.

The real game, however, is medium-term. The Barents is not just an energy frontier. It is emerging as one of Europe’s new security fault lines.
