Algeria, pillar of Italian energy diversification with 20 billion cubic metres of gas in 2025
Italia strengthens its energy security by focusing on Algeria, which supplied more than a third of its national gas between pipeline and LNG in 2025.
Key points
In six years, gas imports from Algeria have grown by 67%, rising from 12 to over 20 billion cubic metres in 2025: 30% of the volumes arriving in Italia by pipeline, to which 2.1 billion LNG should also be added - over 45 loads, 20% of the total of those arriving last year in the peninsula - bringing the total to 36% of all gas injected into the network.
Not to mention that, in January alone, a further 1.8 billion cubic metres arrived at the Mazara del Vallo entry point in the Trapani region, confirming Algeria as the leading supplier of gas by pipeline.
It is no coincidence that yesterday, Prime Minister Giorgia Meloni, who flew to Algiers to meet President Abdelmadjid Tebboune, described the country as 'a partner of absolute strategic importance'.
Flows from the South
The steadily increasing flows through the Transmed, realised between 1977 and 1983 by Eni, actually led to a sort of reversal of the hourglass of supplies.
Previously, methane came from the North, Russia in primis, while with Moscow's invasion of Ukraine in 2022 and the onset of the energy crisis, the largest volumes came from the South: not only from Algeria, but also from Libya (which, in 2025, accounted for 2% of the supply pie) and, above all, from the Tap, the pipeline part of the Southern Gas Corridor that came into operation in 2020 and that transports to Europe the flows ensured by the Azeri Shah Deniz offshore field, located in the Caspian Sea.
