I love how the laymen try to say that H2 propulsion is safe. You wait until the first bimmer goes critical mass on the NJ Parkway and you'll be one of the first ones screaming that Congress should never have let them do this.



When the car is parked for extended periods, the evaporating hydrogen builds pressure that must be safely released. A boil-off system mixes the hydrogen with air, runs it through a catalytic converter and releases water vapor through a rear-bumper vent.

Redundant safety systems abound. If the pressure inside the tank rises too high, a vent in the roof can release gaseous hydrogen directly. And if the car happened to roll over and block the roof opening, hydrogen would reroute through the underbody. A hydrogen detection system makes the car’s four door locks glow red to warn of leaking fuel in the trunk, fuel nozzle area or under the hood; windows automatically open if hydrogen should enter the cabin.

The biggest safety issue is storage. The main explosiveness problems relate to storing H2 as a liquid or pressurized gas. Guess we'll just have to wait for someone to develop a hydride that is light enough and economical enough for mainstream use. That shouldn't take more than 50-100 years...
