Snam is developing Green Hydrogen Valleys, a multi-gigawatt infrastructure program in Southern Europe that links solar and wind projects to new hydrogen pipelines. The initiative focuses on integrated regional clusters where renewable power, electrolysis plants, storage, and dedicated pipelines are built as one coordinated system. Snam aims to repurpose parts of its 38,000 km gas network for hydrogen transport, targeting hard to abate sectors like steel, cement, and chemicals. The projects rely on proximity to large renewable generation sites, multi-megawatt electrolyzers, and connections to deep water ports for potential export. Snam does not manufacture electrolyzers but partners with specialist suppliers. The regulatory treatment of these assets will determine whether they generate stable returns similar to regulated gas infrastructure or more market exposed cash flows. For investors, the key question is whether hydrogen pipelines will receive the same tariff treatment as natural gas networks. Technology risks remain real: electrolyzer lifetimes, pipeline embrittlement, and compressor reliability are all being tested in real time. Snam starts with smaller pilot corridors and plans to scale up as regulatory frameworks and industrial demand mature. The Hydrogen Valleys concept is a concrete bet that hydrogen will play a significant role in decarbonizing heavy industry and long distance energy transport in Europe.
