Future-proof hydrogen containers
Compressed hydrogen enables higher payloads as well as large-scale storage and transportation. Hexagon Purus' Type 4 composite storage solutions already meet the demanding requirements expected of hydrogen containers in the coming years.7 Dec 2023
The storage of hydrogen requires special containers to contain this extremely volatile element. There are currently four different types of pressure vessels on the market, numbered from type 1 to type 4. All four types are used to store gaseous hydrogen, with the pressure range typically being between 200 and 700 bar. The most modern pressure accumulator currently in series production is type 4. The liner is made of plastic (typically polyamide or polyethylene) and, as with its "predecessor" type 3, the jacket is usually made of carbon fiber. This design gives the type 4 pressure vessel a weight advantage over the other three designs.
One of the world's leading suppliers of high-pressure composite containers and systems for the storage and transportation of compressed hydrogen is Hexagon Purus, a Hexagon Composites Group company headquartered in Norway. Over the past decades, Hexagon Purus has adapted its proven Type 4 composite pressure cylinder technology for a wide range of mobility and storage applications in the hydrogen industry. Today, the company's portfolio includes hydrogen cylinders in pressure ratings of 250, 300, 500, 700 and 950 bar. This means that the Norwegians are well equipped for the expected boom in the hydrogen segment.
The type 4 solutions from Hexagon Purus undergo stringent testing procedures with regard to all conceivable eventualities and are therefore intended to guarantee the highest safety and quality standards. It is not without reason that the production facilities are certified to ISO 9001:2008 and IATF 16949:2016.
