Southern Hydrogen Corridor (often referred to as SoutH2 Corridor)

20 MW electrolyzer plant producing 3,100 tonnes H2/year from renewable electricity

One central concept in Southern hydrogen corridor initiatives is the repurposing of existing natural gas pipelines to carry hydrogen or hydrogen‑rich blends, reducing the need to build entirely new long‑distance infrastructure.[7][8] For Algeria, whose gas pipelines connect directly to Southern Europe, this approach could significantly lower initial capital costs for hydrogen exports and accelerate deployment timelines if technical and regulatory challenges are resolved.[4][7]
