Abstract: A method for producing hydrogen using two types of electrolysis systems, the first having an active DC module and at least one first-type electrolyzer producing a first hydrogen output by using a first power from the active DC module, and the second electrolysis system having a passive DC module and at least one second-type electrolyzer producing a second hydrogen output by using a second power from the passive DC module. The method includes increasing the first hydrogen output and when it crosses a first predefined hydrogen output threshold, switching on the second electrolysis system and decreasing the first hydrogen output of the first electrolysis system to the first predefined hydrogen output threshold minus the second hydrogen output, so that an overall hydrogen output of the hydrogen production plant is a sum of the first hydrogen output and the second hydrogen output.

Abstract: A method for controlling operation of an electrolyzer plant includes using a first model to determine first operating points for a first period of time; using a second model to simulate operation of the electrolyzer plant for the first operating points for a second period of time that is shorter than and comprised in the first period of time, the second model being a model having higher prediction accuracy for the operation of the electrolyzer plant than the first model, and determining whether the simulated operation meets a predetermined requirement. Upon determining that the simulated operation does not meet the predetermined requirement, adjusting one or more parameters and/or one or more boundary conditions of the first model, and upon determining that the simulated operation meets the predetermined requirement, setting the first operating points as target operating points for the predetermined second period of time.

Abstract: A method for operating a plurality of electrolyzer-stacks includes determining a concentration of impurities, which is originated by a second reaction gas electrochemically produced at a second electrode type of each of the electrolyzer-stacks, within a first gas stream; generating a trigger signal if the concentration of the impurities of the second reaction gas within the merged first reaction gas exceeds a specific second reaction gas level; identifying at least one electrolyzer-stack out of the plurality of electrolyzer-stacks, which is low performing in respect to excessively feeding second reaction gas impurities into the first gas stream, by measuring a current density of at least one electrolyzer-stack of the plurality of electrolyzer-stacks, if the trigger signal is generated.
