What do you believe the frost point is of 20 ppm H2O in the presence of H2SO4? It won't be far from the point where you can liqefy the basic atmosphere and produce a mix of noble gases. From that point, the energy required to further liquefy the heavier atomic masses is comparable or smaller than the energy cost of cracking water to yield hydrogen.
I think you'll also find that hydrogen is not a "safe" lifting gas even on Venus. I suspect that CO2-H2 mixtures are at least flammable and perhaps explosive at the right mix. Also, if you're talking about carbon nanotube fibres and polymer pressure seals, both are flammable in H2. I'd rather use Helium unless someone can show me detailed safety calculations and prove the relative economics of H2 production vs He.
Note also that since helium is monatomic, you get twice the lifting volume from each atom compared to Hydrogen, which goes someway to offset the ratio difference in the atmosphere..

- There is a place in the solar system away from Earth (not artificial) where conditions are much more similar to our world than what we find on Mars....Where is it? (n/t)
