Abstract: A plant for providing purified hydrogen gas comprises a dehydrogenation unit for releasing a dehydrogenation mixture comprising hydrogen gas and at least one impurity from an at least partly laden hydrogen carrier medium, a separation/purification unit fluidically connected to the dehydrogenation unit, for removing the hydrogen gas from the dehydrogenation mixture, a purge gas feed fluidically connected to the separation/purification unit, for feeding purge gas into the separation/purification unit (6), a thermal conversion unit fluidically connected to the separation/purification unit, for thermally converting a tail gas mixture comprising the purge gas and at least one impurity, and a heat transfer unit for transferring heat generated in the thermal conversion unit to the dehydrogenation unit.
