First LH2 cryogenic tank system for commercial vehicles
Two Austrian Technology Leaders Together Bring their Expertise in the Field of Sustainable Mobility onto the Market: On the basis of know-how from aerospace TEST-FUCHS develops special valves for the first LH2 cryotank system for commercial vehicles made by SAG.
The SAG (Salzburger Aluminium Group) charged TEST-FUCHS GmbH with the development of a 3/2 way valve for its innovative liquid hydrogen (LH2) cryotank system for commercial vehicles. As the first manufacturer the company from Salzburg launches an LH2-tank solution which will be produced in series from 2027. In addition, TEST-FUCHS develops another cryogenic valve for temperatures reaching -253 degrees to fulfill the special requirements of SAG concerning minimized electrical power consumption, leak-proofness as well as market price.
In the framework of the project H2-3-4 TEST-FUCHS transfers the know-how gathered in the last decades in terms of hydrogen applications for special aerospace valves to the commercial vehicles field (in motion) as well as to the constantly increasing number of hydrogen projects in the aviation industry (on air). In 2005 the first cryogenic valves for hydrogen applications in the automotive sector were already developed by TEST-FUCHS. As to cryogenic applications, TEST-FUCHS has been firmly established in the aerospace industry since 1988.
Volker Fuchs, CEO and owner of the TEST-FUCHS group: „I am very happy that we could convince SAG with our hydrogen valves for commercial vehicle applications – all the more so because we have the honor to take these steps with an Austrian innovation leader in the field of commercial vehicles. The confidence in TEST-FUCHS will serve us as a motivation to advance our project H2-3-4 in a focused way and to contribute with our know-how in the area of cryogenic hydrogen applications together with innovative market participants.”
Johannes Winklhofer, development leader at SAG, on the topic of the cooperation: „In order to liquefy hydrogen, it must be cooled down to minus 250 degrees Celsius. In addition to many other technical challenges, this requires a special valve system resistant to the particularly low temperatures. In TEST-FUCHS we have found an experienced partner for this development and. We benefit from its experience in aerospace technology and the highest safety and efficiency standards resulting from it.“
