The H2 storage vessel Carbon4Tank is ready to be applied in heavy-duty trucks and other commercial vehicles.
For H2 tanks to be released on the road, they must be certified. In Europe, type approval on H2 tank systems is governed by the regulation UNECE R 134.
Voith Composites CEO Anna Pointner said: “This certification is an important milestone following an intensive development period. It recognizes the hard work and expertise of our team in producing composites at scale for the automotive industry. Our emphasis on high-quality data is critical when ensuring absolute safety and consistency in manufacturing, which this certification demands."
During the development of the Voith hydrogen storage vessel Carbon4Tank, innovative materials and processes were used and set up from the beginning to enable automotive qualities and high volumes in production. Within the approval tests, the tank had to meet stringent performance requirements to receive certification for on-road service, including testing for burst pressure, pressure cycle life, expected on-road performance, fire safety, component isolation and a combination of these tests.
With UNECE R 134 certification, the towpreg-wound H2 tanks from Voith Composites are now ready for serial production. Voith says that the first truck OEMs are already integrating the tanks into their trucks.
