Abstract (en)

[origin: WO2022184803A1] A system for providing purified hydrogen gas comprises a dehydrogenation unit (2) for releasing hydrogen gas (H2) and a dehydrogenation mixture containing at least one impurity from an at least partly loaded hydrogen carrier medium (LOHC+), a separation/purification unit (6) which is fluidically connected to the dehydrogenation unit (2) and serves for separation of the hydrogen gas from the dehydrogenation mixture, a flushing-gas supply (12) which is fluidically connected to the separation/purification unit (6) and serves for thermal utilization of a residue gas mixture containing the flushing gas and at least one impurity, and a heat transfer unit (10) for transferring heat that has been generated in the thermal utilization unit (9) to the dehydrogenation unit (2).
