Folks , there is a LOT of Hydrogen buried underground , so much in fact , that it can fuel our civilisation for thousands of years - no need for fossil fuels if this "clean" , non-polluting resource could be tapped .
***Also besides being a highly valuable natural resource , such Hydrogen deposits found deep underground validate the fact that the Earth's core , or inner Sun , is a Hydrogen generator (some of which converts to H2O or pristine Primary water reserves deep inside the Earth) , which as per Hollow and Expanding planet theory ultimately causes the hollow planet to expand inside outwards :-
