Zusammenfassung:	Methods and systems for hydrogen self-sufficient production of hydrocarbons from a renewable feedstock are provided. An exemplary method includes providing a renewable feedstock; contacting the renewable feedstock and hydrogen from a hydrogen stream with one or more catalysts to generate an effluent comprising n-paraffins and by-product hydrocarbons having 9 or fewer carbon atoms; separating the by-product hydrocarbons from the effluent to generate a hydrocarbon by-product stream; and feeding the hydrocarbon by-product stream to a hydrogen plant to generate the hydrogen stream. In this exemplary embodiment, the by-product hydrocarbons constitute the entire feed and fuel of the hydrogen plant, and wherein no hydrogen is added from an external source.
