In stationary scenarios some aspects really don't matter.
Mass, doesn't really matter unless we are over what single truck can deliver or can be installed at time. Meaning tens of tons.
Volume, some limits, but still I think few cubic meters is in reasonable space. Compare to oil and gas.
Cost per kwh and cycles is the important ones. They should result in less than grid costs.
Also I would consider safety to be important. Is there risk of fire? In event of fire does it keep burning? Does if off gas something toxic that stays also after? Etc.
