Hydrogen-ready twist: why Snam’s HyGreen pipeline matters for Europe’s energy shift

With its HyGreen hydrogen-ready pipeline concept, Italian gas grid operator Snam is pushing into low-carbon infrastructure. The design aims to move up to 100 percent hydrogen on key routes, targeting industrial clusters and storage sites across Europe.

Snam’s hydrogen-ready pipeline concept HyGreen is emerging as one of the Italian group’s flagship infrastructure products as Europe reshapes its gas networks for low-carbon fuels. The company positions HyGreen as a backbone for transporting blends and, over time, pure hydrogen to industrial users, power plants and potential export hubs in and beyond Italy.

What Snam’s HyGreen pipeline is designed to do

HyGreen is Snam’s label for high-pressure transmission pipelines engineered to be compatible with hydrogen blends from day one and capable, after targeted upgrades, of carrying up to 100 percent hydrogen over long distances. According to Snam’s technical descriptions, the concept covers both new-build lines with hydrogen-ready steel and valves, and selected repurposed natural gas corridors that can be converted to hydrogen service based on demand and safety criteria. This dual approach allows the operator to phase in hydrogen capacity without abandoning existing assets.

The network concept is closely tied to the European Hydrogen Backbone initiative, where Snam is one of the main Southern European promoters. The company has published maps that show prospective hydrogen corridors linking northern Italy with Germany and Austria, as well as routes that could connect North African production to Italian ports and onward to central Europe. These corridors are intended to integrate hydrogen storage sites in depleted gas fields and salt caverns, creating a system that can balance variable renewable generation and large industrial off-takers over seasons.

From a technical standpoint, HyGreen requires materials and operating practices that differ from conventional natural gas service because hydrogen molecules can accelerate steel fatigue and affect seals and compressor performance. Snam’s engineering work therefore focuses on steel grades, weld procedures and component specifications that mitigate embrittlement risks and, where necessary, limit operating pressure when the share of hydrogen increases. Over time, compressor stations and metering systems along HyGreen routes would also need to be adapted to measure, compress and odorize hydrogen or hydrogen blends within regulatory limits.

The commercial logic builds on anticipated growth in hydrogen demand from refineries, ammonia plants, steelmakers and heavy transport corridors that cannot easily electrify. Italy’s geography allows Snam to position HyGreen not only as a national decarbonization tool but as a cross-border service that could move hydrogen from solar-rich North Africa and southern Italy toward central European industrial centers. If realized at scale, such flows would give Snam a new regulated asset base in addition to its traditional natural gas network, supporting long-term revenue streams even as fossil gas demand gradually declines.

HyGreen’s role in Snam’s broader strategy is to anchor investment plans that the company can present to regulators and investors as part of its energy transition roadmap. The regulated nature of transmission tariffs means that, subject to approval by Italian and European authorities, qualifying hydrogen pipelines can earn a return on invested capital similar to that of conventional gas infrastructure. That financial structure is crucial for de-risking large upfront capital commitments in an emerging market where hydrogen volumes and carbon prices remain uncertain.

For now, HyGreen remains largely a design and planning framework rather than a fully built, standalone network. Individual projects that would fall under the HyGreen umbrella are at varying stages of maturity, from early routing studies to more advanced permitting and funding applications under European programs. As policy support for renewable hydrogen production, carbon pricing and industrial decarbonization tightens, these project pipelines will determine how quickly HyGreen moves from maps and regulatory filings to steel in the ground.

Within Snam’s portfolio, hydrogen-ready assets like HyGreen sit alongside biomethane connections, liquefied natural gas import terminals and long-distance gas pipelines that link Italy to Azerbaijan, North Africa and northern Europe. Taken together, this mix reflects the company’s attempt to straddle traditional gas security-of-supply priorities and the EU’s decarbonization objectives, with HyGreen positioned as a bridge toward a future in which molecules in the pipelines are progressively less carbon-intensive.
