Abstract:
PROBLEM TO BE SOLVED: To provide a method of absorbing and/or storing gas. SOLUTION: Gas to be stored is brought into contact with an organometallic skeleton electrochemically manufactured under conditions suitable for absorption of the gas to carry out absorption of gas to the organometallic skeleton, and if appropriate, the conditions are subsequently changed so that release of the stored gas occurs.

Abstract:
The invention relates to a method for the parallel production of hydrogen and of one or more carbon-containing products. In the method, hydrocarbons are introduced into a reaction chamber (R) and are thermally decomposed into carbon and hydrogen in the presence of a carbon-rich granulated material (W). The invention is characterised in that at least a portion of the thermal energy necessary for the decomposition of the hydrocarbon is introduced into the reaction chamber (R) via a gaseous heat transfer medium.
