Hydrogen requires huge amounts of energy to split from water** and a lot of
energy to compress and to keep it cold and it doesn't get on very well with a
lot of metals over time. Also fuel cells need replacing just like batteries
after a number of years.
** Unless you get it from natural gas and in the process waste a lot
of the
energy you would have got from just burning methan but still release all the
carbon that was in it anyway so making it anything but green.

Wind. Put the necessary equipment at the base of every wind turbine,
there are enough out there. No energy waste at all.

Presumably you'd also need a new pipeline from every wind turbine to
somewhere which compressed and bottled the hydrogen for later use?
