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, -2) 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 defects (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/rubber 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.
