Argument: Hydrogen is not readily available on Earth
- Debate: Hydrogen vehicles - con argument.
"So far, hydrogen-powered cars are fuel for future thoughts". USA Today. 21 July 2008 - "Unfortunately there is no readily available source of molecular hydrogen (H2) to be found on our planet. There is lots of hydrogen, but it is found as part of larger molecules, most commonly water or hydrocarbons. To be able to use hydrogen in a fuel cell, those hydrogen atoms must be stripped from hydrocarbons and reformed into H2 or electrically disassociated from oxygen in water."
