Why does the hydrogen need to be pressurized? Do you have a link? If it does need to be why would this be bad? The article I pointed to makes it sound as if the hydrogen only needs to be kept cold.
More Quotes from the article:
"While hydrogen is the lightest element, it has some tricky characteristics. It only becomes liquid at dramatically low temperatures -- -423 degrees Fahrenheit (-253 degrees Celsius). To keep the fuel that cold, fuel tanks in the BMW cars are made of 70 layers of fiberglass and aluminum."
" BMW conducted numerous crash tests to see what would happen if the hydrogen tank was punctured or damaged. Their engineers report the liquid hydrogen dissipated harmlessly into the air."
