1. A hydrogen production system comprising:
a vessel comprising an inlet to receive hydrocarbon;
a reforming catalyst to convert the hydrocarbon into a product gas comprising hydrogen and carbon dioxide, wherein the reforming catalyst is disposed on an inside surface of a wall of the vessel and disposed on multiple resistive heaters in the vessel and an inner wall of the vessel;
the multiple resistive heaters to heat the reforming catalyst and the hydrocarbon;
electrical heaters disposed on an outside surface of the wall of the vessel;
multiple tubular membranes that are hydrogen selective and disposed in the vessel to separate the hydrogen from the product gas into a respective bore of the multiple tubular membrane, the multiple tubular membranes positioned in the vessel in multiple pairs of tubular membranes, with each pair of tubular membranes sharing a longitudinal axis that is aligned with a central axis of the vessel, with each tubular membrane of a pair of tubular membranes comprising a capped end and positioned such that the capped ends of the tubular membranes of the pair of tubular membranes are adjacent; and
a conduit collection header receives the hydrogen from the bore of the tubular membrane.
