Core offering

ErreDue designs and manufactures on-site industrial gas generators using alkaline electrolytic, PEM (Proton Exchange Membrane), and PSA (Pressure Swing Adsorption) technologies to produce hydrogen, nitrogen, and oxygen directly at customer sites. The portfolio spans lab-scale hydrogen generators, industrial-scale nitrogen and oxygen PSA systems, modular plug-and-play units, and large alkaline electrolyzers for green hydrogen and energy transition applications. The company also offers supporting gas purification equipment, electronic gas mixers, and turnkey rental-with-maintenance options in Italy.

Product overview

ErreDue is an Italian manufacturer of on-site gas generators producing hydrogen, nitrogen, oxygen, and zero air for industrial and laboratory applications. The product portfolio centers on alkaline electrolytic technology (Mercury series for hydrogen/oxygen), PEM technology (Sirio for hydrogen), and PSA technology (Venus for nitrogen, Mizar for oxygen, NitroBox for plug-and-play nitrogen). Supporting products include Saturn ultra-pure nitrogen generators, GN INOX stainless steel hygienic generators, and add-on modules such as gas purifiers and electronic mixers. The company also offers Special Applications including hydrogen refueling stations and power station systems. Key differentiators include ATEX-certified electrolytic cells, remote monitoring via Ethernet connectivity, modular and scalable designs, and both rental and sale options in Italy.

Partnerships

Four partnerships are on record, tiered core and minor.

• ENEA (Italy's National Energy Research Agency)coreStrategic or Co-development Partner · 15 April 2026ErreDue and ENEA have extended their joint research partnership by 36 months to November 2028, building on four years of collaboration on alkaline electrolysis, Power-to-Gas integration, and variable renewable-powered hydrogen production. The extended programme focuses on next-generation electrolyser components including membranes, electrodes, and catalysts, advanced plant modelling, and developing young researchers and PhD students in the hydrogen sector. The first phase produced upgraded alkaline electrolysis systems, advanced monitoring systems, and Power-to-Gas plant integration work for synthetic methane production.
• Borsa Italiana / Euronext Growth MilancoreOthers · 6 December 2022ErreDue listed its ordinary shares on Borsa Italiana's Euronext Growth Milan multilateral trading system on 6 December 2022. The listing was managed under the Euronext Growth Milan Issuers' Regulations.
• H2IT (Italian Association for Hydrogen and Fuel Cells)minorOthers · 28 April 2021ErreDue is a member of H2IT, the Italian association for hydrogen and fuel cells that promotes the advancement of knowledge and study of technologies and systems for hydrogen production and use. Membership positions ErreDue as an authority within the Italian hydrogen supply chain.
• Regas S.p.A.coreStrategic or Co-development Partner · 19 February 2021ErreDue and Regas signed a joint agreement to ensure the realisation of green hydrogen generation plants. Regas is described as one of the most qualified companies in the design and management of decompression plants, measurement stations, and specific equipment for the digitalization of gas networks. The hydrogen produced by these plants will be injected into national gas pipelines. This partnership combines Italy's largest electrolyser manufacturer with a leading gas network management company.

Direct peers

• Nel ASA: Norwegian-listed manufacturer of alkaline and PEM electrolyser systems for green hydrogen production. Direct competitor to ErreDue's Mercury and Sirio product lines and the most cited European small-cap comparable for hydrogen equipment valuation.
• ITM Power: UK-based pure-play PEM electrolyser manufacturer supplying on-site green hydrogen generators. Directly comparable to ErreDue's Sirio PEM product family in target use cases (industrial hydrogen, energy storage, refuelling).
• thyssenkrupp nucera: German-listed subsidiary of thyssenkrupp providing large-scale alkaline water electrolysis technology. Direct peer for ErreDue's Mercury alkaline electrolyser range, especially in industrial-scale hydrogen projects.
• Sunfire: German electrolyser company developing alkaline and SOEC hydrogen generators for industrial decarbonisation. Comparable as a European hydrogen technology challenger targeting similar industrial offtakers.
• John Cockerill: Belgian engineering firm offering alkaline electrolyser solutions and integrated hydrogen plants. Direct competitor in industrial-scale green hydrogen projects across Europe and emerging markets.
• McPhy Energy: French electrolyser specialist offering both alkaline and PEM on-site hydrogen generators. Closely mirrors ErreDue's multi-technology positioning and European mid-cap customer base.

Broad incumbents

• Plug Power: US-listed hydrogen ecosystem company building PEM electrolyser, fuel cell, and turnkey hydrogen refuelling offerings. Broad incumbent overlap with ErreDue in on-site hydrogen generation, although Plug is materially larger and US-tilted.
• Cummins (Accelera): Cummins' Accelera platform produces PEM electrolysers and fuel cells as part of a diversified industrial powertrain portfolio. Broad incumbent comparable offering on-site hydrogen generation alongside its core engine business.
• Linde: Global industrial gases major with a growing on-site and merchant hydrogen supply business. Broad incumbent that increasingly competes with ErreDue in on-site generation for refineries, chemical plants, and energy-transition customers.
• Air Liquide: Global industrial gases leader with an expanding hydrogen and on-site generation footprint. A key incumbent that could pressure ErreDue's larger industrial customers and pricing on multi-year hydrogen supply contracts.
