I think the energy facilities being hit are mostly refineries - not storage, and anyways any bulk storage is just temporary for bulk transport for export or to the front, etc, so having it in 25gal cans wouldn't be very helpful!
Countries still have strategic reserves, but usually of crude, not refined product --> decentralized reserves would help with supply cuts by any cause. The benefit would be too individual vs export/frontlines, so won't happen.
