I'm only familiar with reservoirs being applied on a commercial scale for electrical power storage presently. I think there are relatively few new geographical locations that can support that technology. All of the others you mentioned need to be developed and demonstrated at commercial scale as I mentioned in my post. Of the options listed, it seems liquefied hydrogen might have the best potential at large scale. I think we will eventually get there, but if we had the solar and wind capability today, we would not have the storage and infrastructure in place to do away with fossil fuels for some time.
