Framework
3
H2NG mixture combustion emits less CO2 than natural gas one
H2 produced through electrolysis allows the energy storage\transport
coming from overproduction of renewable sources
Storage\transport energy from renewable sources
in Snam network Emission reduction
DecarbonisationContribution of hydrogen injection into gas network
Goal
Snam is experimenting impacts and advantages of the injection of H2 into its gas network, moving in ENERGY TRANSITION towards CARBON REDUCTION and final DECARBONISATION

Gas turbines of compressor stations
CNG distributors
End Users with production processes
sensitive to gas quality
Underground storage in porous
rocks
CONSTRAINTS:
Mixture features (Natural gas up to 10% H2)
• Quality characteristics set by the Ministerial Decree
18 May 2018 for the natural gas transport: respected;
• Materials HE (Hydrogen Embrittlement): checked;
• ATmosphères ed Explosives zones identification:
checked.
Public bodies Involved
National and Local Fire Departments
GoalInjection into a portion of the network of a mixture of H2NG up to 10 % of volume to check compatibility of current infrastructure to transport H2NG mixtures.

Plant
• Snam pressure reduction plant with pre-
heating gas boilers.
Snam plant & Infrastructure
• NO CNG refueling stations supplied
• NO compression stations and storages connected
• Absence of redelivery points interconnected
with City Gates and reduction plant located in an
urbanized area
• Limited gas withdrawal over 3-4 weeks (4 Cylinder
Trailers) – 5% H2
• Industrial end customers with non-critical
production processes (Pasta Factory & Mineral
Water Bottling Plant)
End Users
• Limited gas withdrawal by using 16 Cylinder
Packs – 10% H2
