A method and apparatus for producing hydrogen is disclosed wherein a hydrocarbon gas is fed into an electric reaction technology system to decompose the hydrocarbon gas to hydrogen gas and carbon solids. The electric reaction technology system comprises one or more heating zones, wherein each heating zone comprises one or more heating stations and each heating station comprises one or more heating screens followed by a final near-equilibrium attainment zone without additional heat input. After passing the hydrogen gas through the electric reaction technology system the hydrogen gas and any remaining carbon solids and hydrocarbon gas are cooled. The hydrogen gas and any remaining carbon solids and hydrocarbon gas flow through a scrubber, filter, drier or other phase separation system to remove substantially all of the carbon, leaving hydrogen product. The electric reaction technology system can also be used to pyrolyze hydrocarbons.
