Abstract: An electrolysis installation for decomposing water into hydrogen and oxygen comprises: an electrolysis stack; a water recirculation system supplying water to the stack and comprising a circuit and a recirculation pump, first and second separators for separating from water hydrogen and oxygen respectively produced in the stack; a hydraulic supply means supplying the recirculation circuit with deionised water to compensate for water consumed by production of gaseous hydrogen and oxygen, and an extinguishing means for inertising the first and second separators when the installation is shut down, wherein the extinguishing means comprises first and second relief valves provided on the first and second separators, respectively, wherein the valves relieve pressure in the two separators simultaneously while keeping the water level inside the two separators substantially constant, and the extinguishing means controls the supply means to completely fill the two separators with water once the two separators are relieved

Abstract: Installation for the production and storage of renewable energy (1) provided for supplying an electricity-consuming unit (2) with electricity, the installation comprising solar panels (3) and a hydrogen production unit (4, 7, 8, 9, 10), which comprises an electrolyser (4) provided to produce hydrogen and oxygen when powered by the solar panels (3), a tank (8), and a compressor (10) for injecting the hydrogen provided by the electrolyser into the tank. The installation is characterised in that the solar panels (3) are provided to supply the electricity which they produce as a priority to the electricity-consuming unit (2) until the connected load of the unit is reached. Furthermore, the installation (1) comprises a branch connection unit (6) connected to the output of the solar panels and provided to direct a part of the electricity produced to the electrolyser (4) when the power produced by the solar panels exceeds the connected load.

Abstract: The invention relates to an electrolysis installation for decomposing water into hydrogen and oxygen, comprising: an electrolysis stack (5); a water recirculation system supplying water to the stack, the recirculation system comprising a circuit (11, 13) and a recirculation pump (15), a first and a second separator (7, 9) for separating from the water the hydrogen and the oxygen respectively produced in the stack (5); a hydraulic supply means which supply the recirculation circuit (11, 13) with deionised water so as to compensate for the water consumed by the production of gaseous hydrogen and oxygen, and an extinguishing means for inertising the first and second separators (7, 9) when the installation is shut down, characterised by extinguishing means which comprise a first and a second relief valve (36, 23) provided on the first and second separators (7, 9) respectively, the valves being provided to relieve the pressure in the two separators simultaneously while keeping the water level inside the two separa
