Energy density, storage, and delivery are major stumbling blocks with hydrogen
Can you imagine trusting your typical backwards baseball cap wearing yoof, to fill his car up with hydrogen gas....
Hindenburg anyone
We've had LPG and CNG power systems for cars for decades.
They're a darn site safer than petroleum in an incident!
My last Saab had an LPG conversion. I felt perfectly safe with it
So long as the same safety measures are in place I have no problem with Hydrogen.
