An Italian working group co-ordinated by Snam, RINA and Bormioli goals to cut back emissions within the glass business by utilising hydrogen.
The manufacture of glass objects, of which Italy is the second-largest producer in Europe with over 5 million tonnes per 12 months, is energy-intensive, produces vital emissions and is troublesome to energy with electrical energy.
To deal with this, the ‘Divina’ challenge (Decarbonisation of the Glass Industry: Hydrogen and New Equipment) goals to cut back emissions within the glass melting stage, which accounts for greater than 50% of whole vitality consumption all through the manufacturing course of.

The group, comprising Snam, RINA, Bormioli Luigi, Bormioli Rocco, STARA GLASS, UNI.GE., Stazione Sperimentale del Vetro, IFRF Italia, SGRPRO and RJC SOFT, believes that hydrogen can present a viable resolution by optimising its use by way of vitality and emissions and managing manufacturing and transport challenges.
Snam chief government Marco Alverà mentioned: “Hydrogen will play a key position in decarbonising energy-intensive sectors similar to glass manufacturing to be able to meet home and European local weather targets. This challenge enhances what we’re already doing within the metal, rail transport and ceramics sectors.”
The initiative will make it doable, within the quick to medium time period, to evaluate the outcomes of introducing an rising proportion of hydrogen blended with pure fuel into present melting furnaces working underneath common manufacturing situations.
Testing vital portions of hydrogen on operational furnaces will likely be a possibility to judge the compatibility of hydrogen combustion with glass materials in actual industrial manufacturing contexts following acceptable testing in laboratories.
Ugo Salerno, President and CEO of RINA, commented: “Following the primary check with a mixture of pure fuel and 30% hydrogen in metal processing that we carried out in May, our experience and laboratories are additionally getting used for the ‘Divina’ challenge, an necessary milestone in direction of the decarbonisation of one other of probably the most vital sectors within the Italian economic system.”
Today, the primary vitality supply utilized by glassworks is pure fuel and CO2 emissions quantity to round 1,500,000 tonnes per 12 months: general, round three.5% of the emissions of the whole manufacturing business. Nationwide use of a 30% hydrogen mix in glass melting processes would scale back emissions by 200,000 tonnes, equal to the emissions of round 100,000 vehicles.
The challenge can even outline and subsequently optimise the design guidelines for future furnaces, which may assure the most effective efficiency even with larger hydrogen percentages as much as 100%.
