lel that too
but I'm not joking, it's actually down there
>There is yet another nugget hidden in the remnants of our three example boreholes. As they drilled the deeper parts of the boreholes, they noticed curious bubbling in the drill mud used as it was pushed up. At the Kola site they noted that it was so strong that it behaved like it was boiling.
>At both the Kola site and at the Hole of Germany they duly tested the bubbly stuff and found that it was hydrogen that was bubbling up. At the site for the Bertha Rogers Hole, they just noted that the bubbly stuff burned, but was not useful methane, it is though quite likely to have been hydrogen since it did indeed burn.
>At no site there was any excitement about the hydrogen, no particular follow-up research was done, and to this day we do not know what processes at such great depth produces hydrogen. After all, it was not the holy oil that was discovered, so why would they be interested?
>Several decades later it is easy to scream out of frustration at the wasted opportunity for research into one of todays most promising energy sources.
>Saving the planet is filled with these small little oversights.

I've done some research and apparently hydrogen is produced when common rust is converted into magnetite in presence of silicates, the so-called seprentinization reaction, which occurs at 200-300°C
this hydrogen is in turn how natural gas is formed, when it reacts with coal and longer chain compounds buried underground, it gradually converts them towards methane
but if you actually dig down to 200-300°C layers, and if there are right minerals down there (but this was true in all three cases where it was attempted to drill that far down, one of them in Germany too), you will get pure hydrogen
