Burning hydrogen produces water vapor, a greenhouse gas. Have these people thought about the effect of millions of cars and trucks running on hydrogen and producing steam that is expelled into the atmosphere and will warm the planet?
If hydrogen is used to power vehicles, there will be a tank in which the hydrogen is kept under very high pressure. Has anyone thought about what will happen when the vehicle collides with a bridge or another vehicle? Will the pressurized hydrogen be suddenly released from the tank? How much of it will catch fire?
