Quantity and Pressure limitation

Quantity and Pressure limitation

This LAP¨refers to the quantity and pressure limitations. It underlines what are the requirements and limitations in terms of pressure and quantity of hydrogen for hydrogen transport. Finally, it shows if it is possible to increase the pressure/quantity, and if yes which authority is competent, what is the process to follow, how long does it takes and what are the costs associated if known.

Assessment This legal-admnistrative procedure is needed to ensure safe transport. It is argued, however, that the requirements are interpreted and implemented in a slightly different way in Norway and the EU than for example the US. , and that it should be possible to enter multilaterial agreements (M270) concerning the working pressure of composite cylinders for the carriage of compressed hydrogen. This could reduce the cost of transport and distribution, which is a major barrier to hydrogen deployment. ADR/RID is the umbrella legislation. The interpretation, implementation in practice is different in different parts of the world. Without a uniform interpretation, technology providers in some countries may be disadvantaged, and reluctance to increase the pressure/quantity where this might be done without compromising on safety may be seen to contribute to the high cost of distribution. Efforts to develop new standards are therefore important.
