• Energy ministers of Algeria, Tunisia, Italy, Austria and Germany signed the Algiers Ministerial Declaration on October 1, backing the Southern Hydrogen Corridor.
  • The planned ~3,000 km pipeline would carry 4 million tonnes of renewable hydrogen per year — about 10% of the EU’s projected 2040 clean-hydrogen demand.
  • A dedicated technical secretariat supported by UNIDO will now coordinate the project, but prices, offtake contracts and water supply remain open questions.

The South Hydrogen Corridor took its biggest political step yet on October 1, when the energy ministers of Algeria, Tunisia, Italy, Austria and Germany met in Algiers and signed a ministerial declaration committing their governments to the project. The declaration frames the planned pipeline — roughly 3,000 kilometers carrying renewable hydrogen from North Africa to Europe — as a driver of Euro-Mediterranean green-energy integration.

According to The Business Standard’s reporting on the meeting, the second ministerial gathering on the corridor — known as SoutH2 — brought together Algeria’s Mourad Adjal, Italy’s Gilberto Pichetto Fratin, Austria’s Wolfgang Hattmannsdorfer, Germany’s Frank Wenzel and Tunisia’s Slah Zouari. The declaration establishes a dedicated technical secretariat supported by UNIDO, the UN’s industrial development agency, to coordinate the project’s next phase. Renewables Now independently confirmed the signing as part of the week’s hydrogen news.

What the South Hydrogen Corridor would carry

The headline numbers are striking. The corridor is designed to transport 4 million tonnes of renewable hydrogen per year from Algeria, via Tunisia, to Italy, Austria and Germany — representing roughly 10% of the European Union’s projected clean-hydrogen demand in 2040. A single import route supplying a tenth of a continent’s future hydrogen appetite would make SoutH2 one of the most consequential energy infrastructure projects of the decade, on par with the gas pipelines that have shaped European energy geography for generations.

The logic mirrors the old gas trade in reverse: North Africa has world-class solar resources and abundant land for the electrolysis needed to produce green hydrogen; Europe has the industrial demand and the willingness to pay a premium for clean molecules. Algeria, a historic gas exporter to Europe, sees hydrogen as a way to future-proof that relationship as the continent decarbonizes.

The commercial questions nobody has answered yet

Declarations, however, are not deals. The hard questions around SoutH2 remain wide open. First is price: green hydrogen produced in Algeria, converted, transported 3,000 kilometers and delivered to a German steel plant has to compete with alternatives — including hydrogen produced closer to home, electrification, and, frankly, continued fossil fuel use. Without long-term offtake contracts at bankable prices, pipelines don’t get built.

Second is renewable capacity. Producing 4 million tonnes of green hydrogen per year requires an enormous buildout of solar and wind in Algeria and Tunisia, plus the electrolyzers themselves — investment on a scale that dwarfs anything North Africa has attempted. Third is water: electrolysis needs vast quantities of purified water in a region where water scarcity is already a pressing concern, which likely means pairing the project with large-scale desalination.

These are not reasons to dismiss the corridor — they are the reasons the new UNIDO-backed secretariat exists. Moving from ministerial declarations to final investment decisions means grinding through exactly these issues: who builds what, who buys the hydrogen, at what price, and who finances the gap.

Why hydrogen diplomacy matters now for the Southern Hydrogen Corridor

Step back and the Algiers declaration fits a larger pattern: hydrogen is becoming an instrument of energy statecraft. The EU, determined not to swap dependence on Russian gas for dependence on any single new supplier, is courting multiple hydrogen partners — from the Middle East to Australia to North Africa. The planned SoutH2 pipeline from Algeria to Germany would be the flagship of that strategy — and if built, green hydrogen imports through the corridor could cover roughly a tenth of Europe’s projected 2040 demand. For Algeria and Tunisia, the corridor offers a path to remain energy exporters in a decarbonizing world, with the industrial development and jobs that come with it.

That geopolitical framing is part of why the project keeps advancing despite the commercial uncertainties. Energy security arguments unlock government support, derisking tools, and diplomatic attention that purely private projects struggle to attract. The Southern Hydrogen Corridor SoutH2 pipeline from Algeria to Germany is as much about the future map of energy alliances as it is about molecules.

A project years in the making

The Algiers meeting was the second ministerial gathering on the corridor, which tells its own story: SoutH2 has been working its way through European and North African energy diplomacy for several years, gradually accumulating political sponsors. Each of the five signatories has a distinct stake. Algeria wants to convert its gas-export infrastructure and expertise into a hydrogen future. Tunisia, the transit country, stands to earn transit revenues and develop its own renewable capacity. Italy positions itself as the entry point for Mediterranean energy into Europe. Austria and Germany — Europe’s industrial heartland — need the molecules to decarbonize steel, chemicals and heavy transport that cannot easily run on electricity alone.

That alignment of interests is the project’s greatest asset. Corridors fail when one party’s commitment wavers; here, all five governments have now put their names to a shared institutional framework. The secretariat gives the project a permanent address — a place where the unglamorous work of harmonizing standards, permitting, and financing can actually happen between ministerial photo opportunities.

What’s next

Watch the secretariat’s work program and, more importantly, the first offtake announcements. The corridor’s credibility will be measured not in declarations but in signed purchase agreements from European industrial buyers — steelmakers, chemical companies, refineries — willing to commit to Algerian hydrogen at a defined price. Until those appear, SoutH2 remains what it is today: the most politically advanced green-hydrogen import project in the world, still waiting for its commercial foundation.

The other number to watch is green hydrogen imports to Europe and 2040 demand projections themselves. If EU hydrogen demand grows slower than hoped — as some recent revisions suggest — even a fully built corridor could face a thinner market than planned. The Algiers declaration is a bet that the demand will be there. The next few years will test it.
