You would have to lift the ozone generators. Ozone is unstable, especially in high concentrations so generating it and then lifting it is not plausible.

It’s used immediately as it’s generated for industrial applications, no storage.

Makes sense. It still seems that lifting the generators should be relatively straightforward, but it will be more complicated than lifting particles for stratospheric aerosol injection.

But they are relatively heavy relative to how much ozone they produce and need inputs of pure O2 (more weight to carry) and consume a lot of power (more weight). And it needs to be kept there for a long duration to actually generate much. Weight * time at stratospheric elevations is a big cost…

OK. As I said, these were quick and dirty calculations, so it may very well be that this won't be as cost-feasible as I had imagined.

For ‘particles’ you could design a jet engine that uses liquid Sulphur for fuel when at elevation. Or just a burner with the same. The SO2 gas eventually oxidizes to SO3, and that’s what forms the aerosols for the Sulphur injection approach.

Now eventually they come back down, and it’s quite possible that the SO2 would consume ozone…
