Nature of hydrogen gas
WebGreen hydrogen could be a powerful energy carrier with significant benefits during the energy transition because it can be used in existing fossil fuel infrastructure. By supplementing up to 20% of natural gas with hydrogen, existing natural gas equipment can be used without modification. This eases the transition to clean energy and starts … WebFrom a material point of view, Eq. 1 shows that methane pyrolysis produces two molecules of hydrogen and one molecule of carbon from one methane molecule. In steam reforming, Eq. 4, the conversion of water vapor releases twice the amount of hydrogen, but also one CO 2 molecule. Energetically, the reaction enthalpy for hydrogen production by …
