However, without subsidies, the cost of green hydrogen remains too high to be profitable and converting furnaces and boilers to hydrogen is expected to be a long and costly process.

"Snam intends to make its infrastructure, research and expertise available to contribute to the creation of a national hydrogen supply chain and to the achievement of domestic and European climate targets," Snam Chief Executive Marco Alvera said.

Sounds like they're not yet integrating green hydrogen here, so not necessarily bringing down the carbon footprint-- but still an important step because this testing could be laying the groundwork for that infrastructure to be expanded in the future if/when green hydrogen was available. One would also have to wonder if a direct potential user of green hydrogen might not be the perfect investor in renewable facilities that could generate the fuel during times where supply exceeds demand on the grid!
