Snam, the energy infrastructure company, is experimenting with doubling the amount of hydrogen in the gas blend it delivers in southern Italy.
Initially it delivered a 5% hydrogen mix in Contursi Terme, Salerno, to a pasta factory and a mineral water bottling company.
The increase to 10% means that approximately 7 billion cubic metres of hydrogen will be sent through the system every year. This is the equivalent consumption of 3 million households, and will help reduce carbon emissions by 5 million tonnes.
A joint Snam-McKinsey study found that hydrogen could meet up to 23% of national energy demand in Italy by 2050 in a 95% decarbonisation scenario.
