摘要:
A method for controlling the distribution of electric power from a wind farm to a plurality of hydrogen producing electrolysers. The method includes estimating available DC power from the wind farm, which is controlled independently from the hydrogen producing electrolysers. A target current set point is determined for each electrolyser based on the estimated available DC power, the number of available electrolysers, and the voltage of each electrolyser. DC current supplied by at least one DC-DC power converter to each electrolyser is controlled to bring the DC current to the target current set point. The method is periodically repeated to compensate for changes in the DC power available from the wind farm.
摘要:
An electrolyser module comprising a plurality of structural plates each having a sidewall extending between opposite end faces with a half cell chamber opening and at least two degassing chamber openings extending through the structural plate between the opposite end faces. The structural plates are arranged in face to face juxtaposition between opposite end plates. Each half cell chamber opening at least partially houses electrolytic half cell components comprising at least an electrode, a bipolar plate in electrical communication with the electrode and a membrane. The structural plates and half cell components define an array of series connected electrolytic cells surmounted by at least first and second degassing chambers having an upper section above a lower section. The structural plates define, at least when in face to face juxtaposition, respective gas-liquid passages extending between a top part of the half cell chambers and a bottom part of the upper section of the first and second degassing chambers to provide fluid communication between an anode part of the electrolytic cells and the first degassing chamber and between a cathode part of said electrolytic cells and said second degassing chamber. The structural plates further define, at least when in face to face juxtaposition, respective degassed liquid passages extending between a bottom part of the lower section of the first and second degassing chambers and a bottom part of the half cell chambers for degassed liquid return from the first and second degassing chambers respectively to the anode and cathode parts of the electrolytic cells. The electrolyser module further comprises respective gas discharge and feed water passages extending therethrough and fluidly communicating with the degassing chambers for gas discharge from the degassing chambers and for feed water introduction into the degassing chambers.
