NOVELTY - The hydrogen production system comprises an electric reaction technology system having electric resistance heaters including four heating zones, a selectable heat input into heating stations, an inlet into a first of the heating zones configured for input of a gas from which hydrogen gas is formed, a finishing station for cooling and removal of carbon solids, an outlet configured for output of the hydrogen gas, a heat exchanger disposed after the heating zones configured to utilize heat from electric reaction technology system to heat the incoming gas, and a carbon solid removal component.    USE - The system is useful for producing hydrogen, which is useful as a gaseous raw material for the chemical and petroleum industries.    ADVANTAGE - The system is capable of economically, efficiently and rapidly producing the hydrogen with high purity (95.5 mol.%) and with limited carbon dioxide emission in less consumption of energy thus mitigating global warming, and can be easily operated and maintained.    DETAILED DESCRIPTION - The hydrogen production system comprises an electric reaction technology system having electric resistance heaters including four heating zones, a selectable heat input into heating stations, an inlet into a first of the heating zones configured for input of a gas from which hydrogen gas is formed, a finishing station for cooling and removal of carbon solids, an outlet configured for output of the hydrogen gas, a heat exchanger disposed after the heating zones configured to utilize heat from the electric reaction technology system to heat the incoming gas, a carbon solid removal component after each heating zone configured to remove some or all of the carbon solids, a pre-heater (116) disposed after the inlet and before the first heating zone, a recycling mechanism to recycle a portion of the heated hydrogen gas and any remaining carbon solids and hydrocarbon gas exiting the heat exchanger into the hydrocarbon gas flow, a recycle compressor, a wind-generated electricity source, and a second inlet to introduce a second gas into the first gas stream prior to entering the first heating zone. Each heating zone comprises selectably-spaced heating stations in series, where each heating station comprises heating screens through which process gases flow and a final near-equilibrium attainment zone without additional heat input. The recycled hydrogen passes through the compressor prior to mixing with the input gas. The heating stations are configured to deliver a different heating duty to the system. The electric reaction technology system is disposed in a substantially vertical position with respect to the level ground. A spacing between heating stations increases in the gas flow direction. The heat delivered by each heating station is substantially constant within each zone. The heat duty delivered by each subsequent zone decreases. The heating station spacing varies continuously after the first zone to maintain substantially isothermal conditions by controlling reaction rates and volumes. A temperature varies between heating zones. INDEPENDENT CLAIMS are included for:    (1) a pyrolysis method for producing cracked gas products; and    (2) a pyrolysis system for producing cracked gas products.
