Compressed hydrogen tube trailer
Hydrogen tube trailers are semi-trailers that consist of 10 to 36 cluster high-pressure hydrogen tanks varying in length from 20 feet (6.10 m) for small tubes to 38 feet (11.58 m) on jumbo tube trailers. They are part of the hydrogen highway and usually precede a local hydrogen station.
Jumbo tube trailer
As of September 2013, The Linde Group has introduced a tube trailer operating at 500 bar (50.0 MPa; 7,250 psi) utilizing new, lighter storage materials to more than double the amount of compressed gaseous hydrogen to 1,100 kilograms (2,425 lb), or a normal 13,000 cubic metres (17,000 cu yd) of hydrogen gas. The new trailers can be filled and emptied in less than 60 minutes.
As on July 2016, Nishal Group has multiple cascade configurations in the form of cascade banks operating at 200 bar.
