Abstract
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.

A dihydrogen storage and retrieval method comprising at least:
- a step of generating (G) hydrogen by dehydrogenating hydroxyl groups of dipropylene glycol (DG) into respective carbonyl groups, in order to generate a dehydrogenated substrate (SD) and gaseous dihydrogen (H2), and
- 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).
A dihydrogen storage and retrieval system (1), comprising at least:
- a module for generating hydrogen (2) designed to dehydrogenate hydroxyl groups of dipropylene glycol (DG) into respective carbonyl groups, in order to generate a dehydrogenated substrate (SD) and gaseous dihydrogen(H2), and
- a module for regenerating (3) at least a portion of the dipropylene glycol (DG) designed to hydrogenate said carbonyl groups into respective hydroxyl groups by means of gaseous dihydrogen (H2).
