There never were hydrogen powered airships. Hydrogen provided lift, not propulsion. Propulsion came from combustion engines using diesel or gasoline.
yes, for sure. hydrogen cars are created today.
Hydrogen,Energy,Air and solar powered
New fueling stations that can handle hydrogen would have to be built.
To use less oil

trees they make oxygen
There are no hydrogen powered cars being sold to the general public. Storage and fueling locations, and the potential hazard of the fuel, are the biggest hurdles.
Generally, a Hydrogen powered car runs by using hydrogen and oxygen to create electricity in a fuel cell, which is then used to power an electric traction motor that runs the car. Direct ignition-engines are more difficult and dangerous to 'run'.
"Coradia iLint", the world's first hydrogen-powered train, developed by the French company Alstom, is expected to begin service in Germany in December 2017.Powered by hydrogen fuel cells driving electric motors, the train will emit no carbon dioxide pollution. Its only emissions are steam and water.
