Don’t we have to burn both to produce energy/electricity?
In: 0
Petroleum already exists underground to be harvested. There is little free hydrogen, that is not mixed with gas deposits together with methane and other gases. Hydrogen has either “burned” to combine with other elements or been lost from in space. Hydrogen must be produced by splitting it off bigger molecules with the input of energy from another source. Some of this energy is later recovered as the gas is burned.
