Help on Hydrogen

[Shinigami]

I have to find out about hydrogen as a fuel and list its advantages and disadvantages, I tried looking on the net but can't find anything, help? +rep.

This is all i can currently think of:

Advantages
-It's a clean fuel (when it reacts with oxygen, all that's produced is water)

Disadvantages
-Most of the hydrogen on earth is in water, and to remove it (using electrolysis) needs a lot of energy.
-A storage tank of hydrogen + 1 small spark = one heck of an explosion!
