Hydrogen is planned to be used in large scale in Sweden to remove coal dependency in the heavy steel industry. https://sv.wikipedia.org/wiki/Hybrit (sorry Swedish article only, I am somewhat surprised)

I have also heard statements that transporting Hydrogen through pipelines is more scaleable (because of less land required) and causes less energy loss than electric cables. Much needed in a long country with energy balancing problems like Sweden.
