NPROXX has introduced its advanced type four carbon fibre pressure vessel. The product was certified on 4th February (2019) by the certification authority TÜV.

The pressure vessel operates at a working pressure of 500bar and has a usable H2 capacity of 6.5kh.

As a result of the certification, the NPROXX product is now fully authorised to be used for hydrogen transportation on roads according to the international regulation for transport of dangerous goods (ADR 6.2).

“This certification is a remarkable milestone for NPROXX,” said NPROXX Managing Director, Reinhard Hinterreither.

“This achievement confirms our technical approach is correct, the product is robust and market ready. It enables us to market our advanced carbon fibre pressure vessels and the provision of related services to markets across the globe,” Hinterreither continued.

The ADR 6.2 certification included burst tests, fall tests, burning and ballistic testing and a detailed documentation process.

The new product will come into operation for the first time within a hydrogen fuel station in Germany, where 81 pressure vessels will be interconnected within a 20-foot-container to function as a hydrogen storage system solution.
