Trans-Saharan Gas Pipeline

First proposed in the 1980s and formalised by a 2009 tripartite agreement between Nigeria, Niger and Algeria, the Trans-Saharan line would move Nigerian gas roughly 4,100 km north to Algeria's Mediterranean coast and on into Europe — bypassing the sea route entirely.

It has stalled repeatedly on financing, security across the Sahel, and the competing westward Nigeria–Morocco proposal. Europe's search for non-Russian gas after 2022 revived political interest, but no final investment decision has been reached, and APRN classes it as shelved pending a credible funding structure.

For African engineers, it remains the continent's most consequential unbuilt corridor — a test of whether cross-border gas infrastructure can clear the political and capital barriers the region keeps running into.
