Most hydrogen produced today is consumed very close to where it is produced. Also energy storage and fuel type use cases rank very low on Michael Liebreich's hydrogen ladder. That's a nice tool that ranks different uses of hydrogen by their economic feasibility and overhead. Chemically binding it to something else to store it works of course. Ammonia (NH3) is common for this; and in fact the biggest use case for hydrogen. People have speculated about using that as a fuel. It's much easier to store and transport. And of course these chemical transformations also have an energy cost.
