摘要： Provided are a method by which hydrogen can be continuously and efficiently produced through a dehydrogenation reaction of a formic acid solution even at a low concentration and/or low grade, and a system therefor. This method involves a reaction step for, while supplying formic acid, catalytically degrading the formic acid into carbon dioxide and hydrogen to thereby continuously produce hydrogen. This method is characterized by involving an extraction step for extracting formic acid from the formic acid solution serving as the starting material with the use of carbon dioxide obtained in the reaction step, and then supplying the formic acid to the reaction step.

摘要： The invention relates to a method for storing and re-releasing dihydrogen (1) comprising at least:



a step of generating hydrogen (G) by dehydrogenating hydroxyl groups of dipropylene glycol into respective carbonyl groups, in order to produce a dehydrogenated substrate (SD) and gaseous dihydrogen (H2),
a step of regenerating (R) at least a portion of the dipropylene glycol (DG), by hydrogenating said carbonyl groups into respective hydroxyl groups by means of gaseous dihydrogen (H2).




The invention is particularly suitable for storing dihydrogen as an energy carrier.

摘要： Provided is a hydrogen supply system that supplies hydrogen. The hydrogen supply system includes: a dehydrogenation reaction unit that subjects a raw material including a hydride to a dehydrogenation reaction to obtain a hydrogen-containing gas; a hydrogen purification unit that removes a dehydrogenation product from the hydrogen-containing gas obtained in the dehydrogenation reaction unit to obtain a purified gas including high-purity hydrogen; and a degassing unit that removes an inorganic gas contained in the raw material on an upstream side of the dehydrogenation reaction unit in a flow of the raw material.

摘要： The system includes a reactor vessel having a reactor space bound by a reactor wall. The reactor vessel is arranged for holding a mixture of a catalyst and formic acid in the reactor space. The reactor vessel includes a mixture inflow opening for allowing the mixture to enter the reactor space and a mixture outflow opening for allowing said mixture to exit the reactor space, and a gas outflow opening for allowing hydrogen originating from the mixture to exit the reactor space. A method for hydrogen production includes: providing the formic acid and the catalyst into the reactor space; withdrawing the mixture from the reactor space; heating and/or cooling the mixture to a predetermined temperature range outside the reactor space; and introducing the heated and/or cooled mixture into the reactor space in a predetermined direction having a tangential component arranged for stirring said mixture in the reactor space.
