Quote by: Compugasm  Automobiles are the least effective method of hydrogen consumption. Why use electricity to create hydrogen, trucking it to stations, just so the car can convert hydrogen back into electricity? IMO, an electric car is the way to go. No gas stations needed. Hydrogen is best used in buildings. It needs large tanks and/or pipe distribution, like natural gas. |
Hydrogen has a lot of energy but it's very light. Batteries are heavy and don't hold a lot of energy. On top of that, batteries take time to recharge, while hydrogen just gets squirted in. I'm sure there's some loss when using elelectrical power to produce hydrogen, but there's also some loss in charging and discharging a battery. In short, it comes down to the details. Maybe batteries make more sense for smaller cars while hydrogen fuel cells are best for buses. Either way, we still have the same problem: a strong, cheap and clean power source.
