The main problem with hydrogen is storage, because it's really good at leaking through most materials when under pressure plus it can dissolve in metals, weakening them. Not to mention that container for hydrogen weighs like a hundred times more than hydrogen inside.

all good points.
I've heard that the low energy efficiency in producing it is a problem too
Yes, because we don't really "mine" hydrogen, it is always stuck to something else.
