Answer 1

Cause its easy to refine from water and relatively abundant practically anywhere on earth and throughout the universe. People that invoke hydrogen as the future fuel however neglect the extra steps toward cleanly and efficiently using it. While you can burn it, its a horribly inefficient way of utilizing it and the efficient way, fuel cells, are expensive and fiddly technologies.
