Don't tell the greenies dude, they want to switch us all to hydrogen cars.
However you are incorrect. Pressurized hydrogen is certainly stored, its used as a welding gas and shipped in cylinders all over the place all the time. -Liquid- hydrogen is very difficult to handle compared to propane or gasoline. But compared to refining aluminum its easy. They have a huge tank of liquid hydrogen sitting on the shuttle launch site in Florida, its been there a looooong time.
And hey, when you burn it you get water. What do you get when you burn aluminum? Really abrasive dust.
