I'm wondering why Wind/Solar + Hydrogen isn't discussed more. Green hydrogen can be produced during daylight hours and used in fuel cells in situ or elsewhere when renewable output is low or zero. Same as batteries, but it seems to me it would be cheaper to build longer-term storage, it's more portable, and could co-exist with blue hydrogen in an overall energy distribution network.
I get that there are efficiency losses to go from electricity to hydrogen and back again, but I would think that other benefits might balance. Curious if anyone has in depth knowledge about this.
