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.

What are the pressure requirements and limitations accepted for hydrogen transport by road?
	The standard pressure for gas cylinders is currently 200 bar.
What are the quantity requirements and limitations accepted for hydrogen transport by road?
	Quantities up to 333 kg/l hydrogen per single transportation unit can be transported with minimum requirements according to the ADR.
Is it a barrier?	Yes
Type of Barrier	Structural barrier
Assessment Severity	2
Assessment	The LAP is needed to determine the pressure and the thereto related quantity. One can say that industry will apply standardized cylinders (and other storage possibilities) which itself try to fulfil the requirements regarding investment/cost optimum taking the transportation restrictions – given by the ADR – into account .(in other words, they try to find a ratio of diameter to length which ensures the lowest possible amount of material plus fabrication of the material – taking handling and transportation restrictions – if any – into account. Taking the 500 bar technology of Linde as a basis, one can see that higher payloads are envisaged and supportive to the economic optimisation. If case one intends to use non standardised cylinders the investments for the equipment will increase, the possible max. transportation quantity might decrease (road transport) and at the same time handling will be impeded, subsequently handling and transportation costs will increase. So the development of a technology which enables higher payloads will be a success if becomes the “new” standard

	There is no limitation in terms of pressure, (mostly transported at around 200-300 bars) In terms of quantity, the limitation is connected to the maximum weight the truck can transport.
