Helium is actually worse in many ways, it is expensive, and it is twice as heavy, so it requires more volume to carry the same weight.
Meaning it is more expensive, slower and more vulnerable to the winds.
Atmospheric air is 1.29 g/L. Helium is 0.18 g/L and Hydrogen 0.09 g/L.
So hydrogen can lift 0.09 g more per liter or 7% more than helium.
Not as bad as I thought, but still Helium is less efficient.
Let’s just… uhhh… go back to helium.
