Norwegians have built the world's first large-scale windfarm which converts wind energy direct to hydrogen:

"Situated off the southwest coast of Norway and unsheltered from the elements in the North Sea, Utsira island has launched a pilot project involving the transformation of surplus electricity produced by wind into hydrogen. It can be stored for use on calm days or for when wind god Aeolus is huffing and puffing so hard that windmills can't be used."
