Linde develops new 500-bar H2 storage technology for more efficient transport in trucks
25 September 2013
The Linde Group has developed a new storage technology that will enable a much more efficient transport of larger amounts of hydrogen. The new solution works at a higher pressure of 500 bar (7,250 psi) and uses new, lighter storage materials to more than double the amount of compressed gaseous hydrogen (CGH2) that can be transported in a single truck load.
Successful field tests with the first reference customer have confirmed the clear benefits of the 500-bar technology over conventional 200-bar systems, Linde said.
Our 500-bar technology is another important milestone for hydrogen mobility. It cuts the cost of transporting hydrogen to fueling stations and reduces the amount of space required on site to store the gas.—Dr. Andreas Opfermann, Head of Clean Energy and Innovation Management at Linde
Linde has opened a 500-bar fueling station at its gases centre in Leuna, in the German state of Saxony-Anhalt. Linde developed the new 500-bar trailers in collaboration with compressed gas storage specialist Wystrach GmbH. Each trailer features 100 lightweight composite storage elements developed in collaboration with xperion Energy & Environment GmbH.
Trailers today can store around 6,000 cubic meters of hydrogen at 200 bar. With Linde’s new technology, a single trailer can transport more than 1,100 kilograms, or 13,000 normal cubic meters, of hydrogen gas. In addition, the trailers can now be filled and emptied in less than 60 minutes.
This technology gives bulk customers a cost-effective alternative to existing cryogenic transport solutions for liquid hydrogen (LH2).
From now on, Linde also plans to incorporate the new technology into its hydrogen fueling station concepts.
This project is supported by the Federal Ministry of Transport, Building and Urban Development. NOW GmbH National Organisation Hydrogen and Fuel Cell Technology is in charge of the program coordination.
