There are refillable cylinders.
But you need to fill them from a larger tank. However, that is also refillable.
Once you factor in the outlay for however many cartridges you think you'll need, and your larger tank, and the cost of recharging your tank...
I have no idea if it becomes cost effective or how much shooting you'd need to be doing for there to actually be savings.
