So many things are wrong with this I dont know where to start! But just to pick one: It seems ( oh horror) that you cant store a weeks worth of wind output as hydrogenor in batteries without reguiring a vast amount of bulky storage capacity . But whoever said we would need to? Variable inputs can be dealt with like variable demand already is , by backups, frequency shifting, and soon interactive demand management , plus a bit of storage and imports via a supergrid.
