Commonly referred to as tube trailers, they are built to accommodate a stack of long steel or carbon fibre cylinders which hold gaseous hydrogen under compression, typically at from 180bar upwards. The cylinders are carried in a protective frame. Demand for these trailers is rising worldwide, with Fairfield Market Research estimating that the global market for them will be worth almost $500m(£411m)by2026. Key players in the sector include Spain's Calvera Hydrogen, which has developed a 45ft tandem-axle semi-trailer which carries carbon fibre cylinders full of hydrogen at 517bar (pictured, right). That means it has the highest working pressure of any tube trailer currently available, the Zaragoza-based company contends. |
