Hydrogen is the lightest gas with the smallest atom and with many other unique properties. In recent years it has been gaining favour as a “green gas” with an application as an alternative, zero-emission fuel in the automobile industry. It can also be an embrittling gas and thus has to be used taking great care with respect to the characteristics of the container material to prevent any hydrogen induced cracking.
Hence Faber has, over the years, followed well established principles (see EN ISO 9809-1 and EN ISO 11114-1, -4) such as using steels, whose tensile strength is limited to a maximum of 950 MPa for cylinders with working pressures of around 250 bar and a range of non-destructive tests to ensure that no deleterious imperfections (which if present could lead to a premature failure) are present. However, for fuel gas applications where working pressures around 1000 bar can prevail, Faber has developed its own high pressure hydrogen research. This development facility, based at one of their manufacturing locations in Cividale, Italy, ensures that only safe materials are ever used. The safety is ensured not only for Faber’s seamless (Type 1) hydrogen cylinders, but also for our Types 2,3 cylinders, which are steel lined and Type 4 (plastic lined) vessels .
Members of Faber's Technical Department are active participants in a number of European hydrogen initiatives. These have included Storhy and Hycomp projects. Our hydrogen cylinders are used throughout the world in a wide variety of applications by a host of different customers.
Being the only worldwide manufacturer of all four Types (1,2,3,4) of hydrogen cylinders, our customers use them for static storage, industrial applications (recreational balloons, margarine, fertilizer, soap etc.) refilling stations, fuel cell usage and of course transport just to mention a few. The other unique aspect of Faber’s cylinders, is the fact we manufacture not only the shells, but also fabricate in-house, the liners for all Types of composites.
Depending on the eventual use, Faber caters for a number of working pressures from the usual 200 bar for industrial users to 1100 bar when used for storage and a corresponding range of manufacturing standards/regulations. The latter include the widely used ISO 11119 series, EN 12245, EN 12257 etc. All our cylinders are fully manufactured in-house and also certified/tested in our newly equipped test laboratory, by third party inspection bodies who have been appointed by Competent Authorities (Government).
