The invention relates to a method for producing hydrogen, in which, in a non-electrolytic method, a carbonaceous feed material is converted into non-electrolytically produced hydrogen and one or more further non-electrolytically produced products, and furthermore excess steam is provided using the non-electrolytic process. According to the invention at least a part of the excess steam is used at least intermittently to provide feed steam, which is converted by means of steam electrolysis to electrolytic hydrogen and electrolytic oxygen. The present invention also relates to a corresponding plant.

A series of three chemical reactions, including a combination of endothermic and exothermic reactions, is used to generate, store, and supply on-demand heat from renewable energy sources for use in a variety of processes. Products from one reaction are used in the next reaction, and the series of three reactions is carried out once or more than once, optionally as a closed loop process.

Disclosed are apparatuses, systems, methods, and devices for generating hydrogen pyrolysis of hydrocarbons (methane, diesel, JP8, etc.) in a reactor. The reactor includes multiple channels in parallel. A hydrocarbon flows in a channel and decomposes into hydrogen and carbon. Hydrogen gas flows out and some of the carbon will deposit on the channel wall. Once carbon deposition reaches a predetermined level, the hydrocarbon flow stops, and air or oxygen is caused to flow into the channels to oxidize carbon into carbon monoxide or carbon dioxide and supply heat to neighboring channels. Simultaneously, the hydrocarbon will flow into neighboring channels causing decomposition into hydrogen and carbon in the neighboring channels. When the carbon coating in the neighboring channels reaches a predetermined level, the gas flow is switched again to air or oxygen. In this way, each channel alternates between decomposing the hydrocarbon and oxidizing the deposited carbon.
