World’s first test with 30% mixture of natural gas and hydrogen in steel forging |
The world’s first test of a 30% natural gas / hydrogen mixture in steel forging was successfully carried out thanks to a collaboration between Snam, RINA and the GIVA group.
The test took place in Italy at the Forgiatura A. Vienna factory and was used to power furnaces.
The trial involved the use of the hydrogen / gas mixture to heat the furnaces at the Forgiatura A. Vienna factory and was successfully carried out on site after a series of studies and laboratory tests lasting approximately a year.
The companies involved in the initiative were:
– Snam, one of the world’s leading energy infrastructure companies and project developer and promoter;
– RINA, a multinational engineering inspection, certification and consulting company, which managed the engineering analyzes and the laboratory phase; and
– GIVA Group, a world leader in the steel industry which made the Forgiatura A. Vienna plant available for field testing.
The mixture of methane and hydrogen was supplied by Sapio, an Italian company specializing in the production and marketing of industrial and medical gases.
Marco Alverà, CEO of Snam, commented: “In the medium and long term, hydrogen is in a position to become the solution for decarbonizing the steel industry as well as all the industrial sectors which are difficult to reduce and which have a fundamental role in our economy.
“This test is a preparatory step for the gradual introduction of zero-emission hydrogen, first mixed with natural gas and then in pure form, in certain steel production processes. Snam intends to make its infrastructure, research and expertise available to help create a national hydrogen supply chain and achieve national and European climate goals. “

Ugo Salerno, CEO of Rina, added: “This test is concrete proof that the hydrogen production chain in Italy can significantly contribute to the decarbonisation of complex and energy-intensive industries such as the steel industry. At Rina, we are proud to play an active role in the current energy transition, more particularly in such events where we can share our energy and industrial know-how.
Jacopo Longhi Vienna, from Giva Group, said: “Hydrogen can be an excellent ally for our Group. On the one hand, increasingly stringent measures on CO2 emissions, coupled with our desire to reduce the environmental impact of our production processes, push us to find a solution.
“On the other hand, the use of hydrogen could create a buoyant market for valves and actuators produced by the Group’s subsidiaries. This project marks only the beginning of a path in which we will be committed for the years to come.

Potential of the Hydrogen project
The use of the mixture of hydrogen and natural gas did not require any modification of the plant and had no impact on the equipment used (industrial burners) or on the characteristics of the heat-treated end product.
The potential of the project in terms of environmental sustainability and economic competitiveness is significant. It is estimated that the permanent use of a 30% green hydrogen mixture, powered by renewable energies, on the total gas consumed by the three steel forging plants of the GIVA Group for its industrial processes would lead to a reduction significant CO2 emissions of around 15,000 tonnes per year, ie 7,500 cars.
This would therefore result in CO2 emissions savings of approx. $ 977,000 per year (calculated on current certificate purchase) while ensuring the value and integrity of the steel forging manufacturing process and its long term environmental sustainability.
Steel is also the material through which pipelines are made; these pipes will play a fundamental role in the transport of hydrogen by supplying end customers.
The use of hydrogen in hard-to-reduce industrial applications such as the steel industry will play a key role in achieving national and European climate neutrality targets by 2050. Green hydrogen is the solution for the future ideal for CO2-manufacturing and processing of seamless steel.
Snam is committed to making its infrastructure hydrogen-ready for the transport of increasing quantities of hydrogen and to promoting its use in high-potential industrial sectors, including the steel industry.
