Enquiring minds and all.

#2 Keep in mind that in the Hydrogen Economy, Hydrogen gas cylinders will replace gas tanks. In order to get the range up, the pressure and capacity will have to be much higher than that used in acetylene gas bottles.

#4 Keep in mind that in the Hydrogen Economy, Hydrogen gas cylinders will replace gas tanks. In order to get the range up, the pressure and capacity will have to be much higher than that used in acetylene gas bottles.

Fortunately, industry standards will probably allow us to avoid current design restrictions for regular compressed gas cylinders. The existing industrial tanks have an exit orifice the diameter of a pencil. This means that in a catastrophic failure anywhere up to a few thousands pounds of pressure can end up venting through such a narrow constriction.

Facilities managers I've worked with often have spoke in hushed and awed tones about how gas cylinders that toppled and had their regulator mounts cracked off abruptly turn into high-pressure jet engines that proceed to fly through such mere obstructions as people, curtain walls, vehicles and so forth, often never to be found ever again.

New designs for vehicular hydrogen fuel tanks will most likely incorporate special safety release ports andnecessarilyincredibly strong composite materials in their construction. Thin wall high-strength alloys with vacuum barrier insulation and carbon-fiber cladding spring to mind.

#5 That sounds expensive, Zenster.

#6 Zenster, the TV show Mythbusters recently gave a demonstration of what gas cylinders could do.
