A system includes a high temperature electrolyser, a first supply line of the electrolyser configured to supply the electrolyser with steam, a first discharge line of the electrolyser configured to discharge dihydrogen from the electrolyser, a second discharge line of the electrolyser configured to discharge dioxygen from the electrolyser, a first heat exchange module configured to ensure a heat exchange between the first supply line and the first dihydrogen discharge line, and a steam generator arranged on the first supply line, upstream from the first heat exchange module, and configured to produce steam from liquid water. The system also includes a module for depressing a section of the first supply line and having an expansion device and a compressor. The expansion device is arranged on the first supply line upstream from the steam generator, and the compressor is arranged on the first supply line downstream from the steam generator.
