When you get plastic you can use plastic drums to store fluids/gasses in them. You can automatically fill/unfill empty/filled drums in a canning machine and then store the full ones in a item storage barrel. That way you can store HUGE amounts of stuff relatively cheaply. I used this to build a sort of a huge tank for storing gasses like oxygen, hydrogen, SO2 etc… without using tons of metals for it.
