Abstract (en)

[origin: GB2612985A] The present disclosure relates to an electrolysis system (200) for generating hydrogen, the system comprising an electrolyser (202) comprising an electrolyte water inlet, a first gas outlet (204) and a second gas outlet (206), an electrical generator (212) configured to generate electricity (212), that can be used in the electrolyser. The electrical generator (212) is connected to the first and/or second gas outlet (204, 206) of the electrolyser and configured to be powered, at least in part, by gas flow provided via the first and/or second gas outlet. The system also comprises an electrolyte pump (214) for supplying the electrolyser (202) with electrolyte water. The electrical generator (212) is a motor-generator comprising a first mode for generating electricity and a second mode for using electricity to drive the electrolyte pump (214). A method of recycling energy in an electrolysis system is detailed as well as an electrolysis system where the electrolyte pump (214) for supplying the electrolyser (202) with electrolyte water and where the electrolyser powers, at least in part, the electrolyte pump.
