There were some recent articles suggesting that there may be enough natural hydrogen seeping out of the ground to supply all of humanity’s energy needs. It seems a bit unlikely that leakage of hydrogen from fuel systems would matter much in comparison.

How about radon, is that fissible?

No, it gives off alpha particles and gamma rays. Hypothetically, you could build a device to harvest that energy (along the lines of an RTG), but the energy density and conversion efficiency would be laughable, given the 3.8 day half-life and gaseous state.

To be clear, I’m saying enough hydrogen to power humanity chemically, not by fusion.

Enough hydrogen to power humanity by fusion is readily available anywhere :)
