Do you have any example where primary (non-rechargable) cells are used in the grid? I think all storage we are talking about for OSM is either connected to a nationwide or local grid and serves as a buffer. I can't come up with an application where they would power a grid with primary cells.

That's one of the things that I found most complicated.They are kind of an energy storage at least they are considered as such by most. But only in combination with a power generator burning the fuels again, they actually become one that serve the electricity gird. I guess you could tag them as storage, if they are an enclosed facility producing, storing and burning powert-2-gas. Probably doesn't make sense for individual electrolysers.
So the question is how we would tag the electorlyser part within such a facility.

I agree with you. storage=battery could be sufficient. I chose storage:type because it was closer to the way we tag generators and plants.
I'd like to hear other peoples opinions on that as well.
