1. A method comprising:
exposing, within a pyrolysis chamber, a hydrocarbon feed stream comprising a hydrocarbon and hydrogen to heat in an absence of oxygen to convert the hydrocarbon feed stream into a solids stream and a gas stream, the solids stream comprising carbon, the gas stream comprising hydrogen;
separating the gas stream into an exhaust gas stream and a first hydrogen stream comprising at least a portion of the hydrogen from the gas stream;
separating the carbon from the solids stream to produce a carbon stream;
performing electrolysis on a water stream comprising water to produce an oxygen stream and a second hydrogen stream, the oxygen stream comprising oxygen, the second hydrogen stream comprising hydrogen;
combining at least a portion of the oxygen of the oxygen stream and at least a portion of the carbon of the carbon stream to generate power and a carbon dioxide stream comprising carbon dioxide, wherein a first portion of the generated power is used to perform electrolysis on the water stream; and
providing a second portion of the generated power to a heater of the pyrolysis chamber to generate the heat within the pyrolysis chamber.
