Few energy transitions in modern history have been as rapid or as economically consequential as Europe’s move away from Russian pipeline gas following the full-scale invasion of Ukraine in February 2022. In just three years, the European Union — which had relied on Russia for approximately 40% of its gas imports — has fundamentally restructured its supply mix, built new LNG import infrastructure, forged new supplier relationships, and reduced overall gas consumption dramatically. As 2026 progresses, European gas security looks considerably more robust than many feared possible in early 2022. But the transition has come at significant economic cost, and structural vulnerabilities remain.
The Supply Transformation
Russian pipeline gas deliveries to the EU, which stood at around 150 billion cubic metres (bcm) per year before 2022, have fallen to near zero for most member states. The final major pipeline route — through Ukraine — saw its transit agreement expire at the end of 2024 and was not renewed, ending the last significant flow of Russian gas to central and eastern Europe via this route. Some smaller central European states, including Hungary and Slovakia, have continued to receive Russian gas via the TurkStream pipeline, but these volumes are modest relative to pre-war levels.
The supply gap has been filled through a combination of increased LNG imports, higher pipeline deliveries from Norway and Algeria, and demand reduction. EU LNG import capacity has expanded dramatically, with new floating storage and regasification units (FSRUs) deployed rapidly across Germany, Italy, the Netherlands, Greece, and elsewhere. Europe’s LNG import capacity has roughly doubled since 2021, providing access to global LNG markets at scale for the first time. The IEA has documented this transformation in detail in its Europe gas security reviews.
LNG Becomes Central
Liquefied natural gas — chilled to -162°C and shipped in specialised tankers — now accounts for approximately 35–40% of the EU’s total gas imports, up from around 20% before the Ukraine war. The United States has become the single largest source of LNG for Europe, with US export terminals running at or near capacity and a significant share of output directed to European buyers. Qatar, Australia, and Norway (which also ships pipeline gas) are other major suppliers.
The shift to LNG has made European gas prices more closely linked to global LNG market dynamics, including competition from Asia. During periods of high Asian demand — particularly following cold winters in Japan, South Korea, and China — European buyers face competition for cargoes and prices rise. This global market linkage represents a structural change from the pre-war era, when European prices were largely set by long-term contracts with Gazprom at relatively predictable levels.
Storage: Lessons Learned
One of the most important policy changes post-2022 has been the establishment of mandatory gas storage targets across the EU. Member states are now required to fill underground storage facilities to at least 90% capacity by November 1 each year, ahead of the winter heating season. European storage began the 2025-26 winter season at approximately 95% capacity — close to the maximum — providing a substantial buffer against supply disruptions or cold weather spikes. By contrast, in October 2021, European storage was well below average, contributing to the energy price crisis of that winter.
Storage filling has become an annual exercise in competitive procurement, with EU buyers purchasing LNG and pipeline gas aggressively through the summer months when demand is lower and prices typically fall. The European Commission has also facilitated joint purchasing initiatives, though voluntary rather than mandatory schemes have seen variable uptake among member states.
Demand Destruction: A Mixed Legacy
European gas consumption has fallen significantly from pre-war levels. The EU’s gas demand in 2025 was approximately 330 bcm, compared to over 400 bcm in 2021. Some of this reduction reflects genuine structural change: accelerated deployment of heat pumps, improved building insulation, fuel switching in industry, and the closure of some energy-intensive manufacturing. Some reflects demand destruction: industry — particularly energy-intensive sectors like chemicals, ceramics, glass, and fertilisers — has simply cut output or relocated production outside Europe in response to persistently higher energy costs.
The competitiveness implications have been severe for European heavy industry. European gas prices, even after falling from their 2022 highs, remain structurally higher than pre-war levels and substantially above prices in the United States or the Middle East. This has contributed to a challenging environment for European industrial competitiveness and has featured prominently in EU policy debates about industrial strategy and the risk of carbon leakage.
New Supplier Relationships
The EU has invested heavily in diversifying its supplier relationships. Norway’s pipeline deliveries — primarily through the North Sea interconnectors — have been running near maximum technical capacity, and Norway has become even more central to European gas security than before. Algeria has maintained its deliveries to Italy and Spain, and the Trans-Mediterranean and Medgaz pipelines continue to operate at high utilisation rates.
Azerbaijan, which supplies gas to Italy and southeastern Europe via the Trans-Adriatic Pipeline (TAP) and the broader Southern Gas Corridor, has attracted EU investment to expand capacity. Azerbaijan’s gas is seen as a strategic alternative to Russian supply for southeastern Europe, though capacity constraints limit how much this option can be scaled.

Looking Ahead
Europe enters the spring of 2026 in a broadly comfortable gas supply position. Storage inventories are in good shape, LNG import infrastructure is expanded and diversified, and demand remains structurally lower than pre-war levels. The immediate crisis of 2022 has been navigated. However, medium-term challenges remain. The new LNG import infrastructure represents long-term capital investment that creates its own lock-in risks if the EU moves aggressively to decarbonise its heating and industrial sectors as planned under the European Green Deal. Balancing gas security today with the green transition imperatives of tomorrow is the defining challenge for EU energy policy in the years ahead.
