Algeria and Niger have restored diplomatic relations in February 2026 after a 10-month standoff, unlocking the path for construction to begin on the trans-Saharan gas pipeline, one of Africa’s most ambitious cross-border energy infrastructure projects. The pipeline will stretch 4,128 kilometres from Nigeria through Niger and Algeria to the Mediterranean coast, where gas can be exported to Europe. Construction authorisation is scheduled for late March 2026, following the conclusion of Ramadan, with Algeria’s national energy company Sonatrach designated as the lead construction entity. The total project investment is valued at approximately $13 billion across multiple construction phases.
Key points
- Algeria and Niger restored diplomatic relations in February 2026 after a 10-month break, unblocking the pipeline project
- The trans-Saharan gas pipeline will run 4,128 kilometres from Nigeria through Niger and Algeria to the Mediterranean
- Construction is authorised to begin in late March 2026 with Sonatrach as lead construction entity
- Total project investment is estimated at approximately $13 billion across multiple phases
- The pipeline will transport up to 30 billion cubic metres of natural gas annually when fully operational
- The project is designed to supply European energy markets, which are actively seeking alternatives to Russian gas
- Nigeria, Niger, and Algeria will all benefit from transit revenues and expanded gas export capacity
The geopolitical timing of this diplomatic reset is significant. Europe’s desire to diversify away from Russian gas has made African gas infrastructure a strategic priority for the EU, and the trans-Saharan pipeline represents one of the most viable long-term supply routes available. For Nigeria, the pipeline creates a northern gas export route to complement existing LNG facilities. For Niger, it brings transit revenues and development investment to one of the world’s least developed economies. For Algeria, it reinforces the country’s position as a critical energy bridge between sub-Saharan Africa and Europe.
Why it matters: If completed, the trans-Saharan pipeline would fundamentally reshape the energy relationship between Africa and Europe, establish a new continental gas corridor, and generate significant long-term revenues for all three partner countries. The diplomatic breakthrough that makes construction possible is as significant as the infrastructure itself.
