Hydrogen seems sensible - you can make it on site (yes, you need a big

What, liquid hydrogen? How many litres is that for 500 miles?

Dont even go there. Hydrogen is enormously bulky and bloody dangerous.
Colorless, odorless, leaks out of any pipe that isn't perfect - teh
explosin at fukushinma was from far less than a car tank of hydrogen..

Unlike, say, methane or LPG ?
