CONTURSI TERME, ITALY - 11 FEBRUARY 2020: The gas pipes that inject a hydrogen blend are seen here in the Contursi Terme gas reduction station in Contursi Terme, Italy, on February 11th 2020.
In April 2019, Snam was the first company in Europe to introduce a blend of 5% hydrogen and natural gas in its transmission network. The trial involved supplying H2NG (hydrogen-natural gas blend) for a month to two industrial companies in the area, a pasta factory and a mineral water bottling company. The trial at Contursi was repeated in December 2019, doubling the hydrogen blend to 10%.
Applying a permanent 10% hydrogen blend to the total gas transported annually by Snam would mean that 7 billion cubic meters could be injected into the network each year, which is equivalent to the annual consumption of 3 million households. This would allow for a potential reduction of carbon dioxide emissions by 5 million tons.
Italy is optimally positioned to become a leading hub for green hydrogen from North Africa to
Europe. Italy could use its solar resources and its existing connection to North Africa (which has even better
solar resources) to set up a leading hydrogen hub.
Snam is one of the world’s leading energy infrastructure companies and first in Europe by gas transmission network size (32,625 km in Italy, over 41,000 with international subsidiaries) and storage capacity (16.9 billion cubic meters in Italy, more than 20 bcm with international subsidiaries).
In September 2018, together with other European companies, Snam signed a Hydrogen Initiative declaration to support hydrogen’s potential as a sustainable energy source. The signatory companies have undertaken to gradually integrate hydrogen into gas transmission networks and to encourage their use as a solution for energy storage, as well as to support the development of hydrogen produced by electrolysis, which allows more efficient use of energy intermittent renewables.
Snam has recently doubled the volume of the hydro
