De Nora, an Italian multinational company specializing in electrochemistry and a leader in sustainable technologies and the emerging green H₂ industry, is partnering with Maffei Sarda Silicati to build a green H₂ production plant located in the Sardinian municipality of Ossi (Sassari).

The project, financed through PNRR funds and promoted by the local company Maffei Sarda Silicati - operating in the field of extraction, processing, and marketing of raw materials mainly intended for the ceramic and hollow glass markets- is coordinated by Make Energy as technical advisor and sees De Nora involved for the supply of its Dragonfly® small electrolyzer, with a production capacity of 1 MW.

The production site, located on a decommissioned industrial area in the municipality of Ossi, will be redeveloped by Maffei Sarda SilicatI itself and will generate about 50 tpy of H₂, which the Sardinian company will use to power its industrial plant, partly replacing the fossil fuel currently used, with significant decarbonization benefits. In addition, the green H₂ plant will be powered by a new 1.5 MW photovoltaic plant located in the same area, thus ensuring a 100% sustainable industrial process.

Significantly, the role of the municipal administration, which is in charge of issuing the compulsory authorizations for the construction of the plant, was immediately welcomed by the Mayor of Ossi - Pasquale Libinu.

In addition to meeting Maffei Sarda Silicati's energy needs, the green H₂ thus generated may have various applications, such as in sustainable mobility, industry, power generation, and heating, positively contributing to the decarbonization of the Sardinia Region.

Paolo Dellachà, CEO of De Nora, commented, “We are proud to have been selected as a partner in this project that will significantly boost Sardinia's green transition. Through its sustainable and innovative solutions, such as the Dragonfly® electrolyzer, De Nora is once again a facilitator of green production processes, positively impacting territories and communities. Our electrolyzer, developed in-house and patented, is confirmed to be a leading product, particularly suitable for local industrial needs, as a modular plug-and-play solution.”

Federico Fiorelli, President of Maffei Sarda Silicati, added, “Maffei Sarda Silicati SpA is pleased to announce the agreement reached with the company De Nora; agreement implemented for the construction and installation of a 1-MW electrolyzer by June 2026 that will be used for the production of green H₂. The H₂ will be fed into the drying process of the sands mined by the company, with a significant reduction in CO₂ emissions. This is yet another step that Maffei Sarda Silicati SpA is taking to achieve zero emissions within all its activities and increasingly in line with its policy of respect for the environment.”

Pasquale Libinu, Mayor of Ossi said, “The topic of renewable energy sources has become increasingly relevant; the innovative project presented by Maffei and the PNRR funding achieved is also a good result because they are located on a site that was exploited from a mining point of view, then restored and now again affected by this intervention. The future, which requires more and more energy, is not in coal or other fossil sources but in the use of clean energies, which must be realized not only because they are incentivized but because they are necessary for the environment."
