Most Hydrogen is made from Methane gas etheir naturally occuring or
from cracking crude. When you make Hydrogen from Methane you get
Hyddrogen and Ammonia which is used in fertilizer production. They
have been searching for years to fund a cheap way to split Hydrogen
and Oxygem atoms apart in water for unlimited fuel source but right
now it take more energy to make it han is recoverd when using water.

Most Hydrogen is made from Methane gas etheir naturally occuring or
from cracking crude. When you make Hydrogen from Methane you get
Hyddrogen and Ammonia which is used in fertilizer production. They
have been searching for years to fund a cheap way to split Hydrogen
and Oxygem atoms apart in water for unlimited fuel source but right
now it take more energy to make it han is recoverd when using water.

In the universe yes as stars and vast clouds of interstellar gas are
made mostly of hydrogen but on the earth, free hydrogen in its native
state is rare. Given the tempatures needed for it to because a liquid
it is easy to see why. Hydrgen is a building block though is all
fossil fuels but it is not in the form of free atoms.
