This is a most excellent place for technology news and articles.
Just need to waste a ton of energy extracting it then liquifying it then hoping that transport doesn't face any issues (and I mean, considering our track record with petrol which doesn't corrode everything it touches I sure as hell wouldn't worry about it [/s if it wasn't clear]) and then fill up your personal car that could have simply been powered by electricity from the beginning...
Also, ever heard of energy density? Because hydrogen won't win prizes on that front!
