Should nations prioritize international partnerships to secure future renewable energy supplies?
Officials from Algeria, Tunisia, Italy, Germany, and Austria convened to advance the SoutH2 Corridor, a project designed to transport four million tons of hydrogen annually. The proposal relies on retrofitting existing pipeline infrastructure for a phased construction start in the early 2030s.
Why it matters
The initiative aims to create a major trans-Mediterranean energy route, enabling Algeria to diversify its exports while providing European markets with large-scale hydrogen supplies. The project's dependence on repurposing gas pipelines is a critical strategy to lower total capital expenditure.
The proposed 3,300-kilometer corridor is designed to leverage existing assets, with 65% of the route utilizing retrofitted gas infrastructure. Technical feasibility is currently supported by a €24 million European Union grant provided to Snam.
The players
Sonatrach
The Algerian state-owned oil and gas company that manages extensive hydrocarbon infrastructure and is currently testing hydrogen production.
Snam
An Italian energy infrastructure operator specializing in natural gas transport and storage that is leading technical feasibility studies for the corridor.
VNG
A German natural gas wholesaler and infrastructure operator that is collaborating on hydrogen technology testing in North Africa.
The details
The project involves transporting hydrogen from production sites in Arzew through Tunisia and across the Mediterranean to Italian terminals, eventually reaching Austria and Germany. The core mechanism involves repurposing legacy natural gas pipelines to accommodate hydrogen, which requires modifications to withstand hydrogen-induced embrittlement—a process where high-pressure hydrogen makes metals brittle and prone to cracking. Sonatrach and VNG are currently testing green hydrogen production technologies in Algeria to validate the supply side of the corridor.
Timeline
January 2026: The involved parties signed a declaration of intent in Rome.
2025: The European Union allocated €24 million for technical studies.
Late September 2026: A German business delegation assessed infrastructure in Algeria and Tunisia.
October 1, 2026: Delegates met in Algeria to advance the project.
Early 2030s: A phased construction launch is planned.
The Tech Race
The SoutH2 Corridor follows the strategic development patterns established by the European Union's Hydrogen Backbone initiative. This project marks a significant scaling attempt to link North African renewable output with central European industrial demand via repurposed pipeline architecture.
The project aims to lower the long-term cost of green hydrogen for European industrial consumers by utilizing existing pipeline assets instead of building entirely new networks. The timeline for initial operations is currently set for the early 2030s.
The takeaway
The project hinges on the successful technical retrofitting of existing gas pipelines to handle hydrogen transport. Stakeholders should monitor the outcomes of the current production testing in Arzew and the subsequent finalization of the corridor’s financial structure.
