摘要： The disclosure relates to a method for allocating electrical energy within an electrolysis plant for producing oxygen and hydrogen. The electrolysis plant comprises a system control device and at least two management apparatuses. Each management apparatus comprises at least one management control device and at least two electrolysis devices. The allocation method comprises method steps and method sequences by means of which the electrolysis process can be particularly advantageously controlled. Thus, a particularly flexible design of the electrolysis process can be implemented, while at the same time high efficiency and an extended service life of the individual components of the electrolysis plant are achieved. The flexible design of the electrolysis process is reflected especially in an expanded range of application of the electrolysis plant.

The apparatus includes an electrical resistor positioned in the storage space, a pair of electrodes positioned at ends of the electrical resistor for being connected to an electricity supply network and a plurality of storage granules positioned for at least partly filling the storage space. The storage granules define a thermal storage mass configured to receive thermal energy from the electrical resistor and to release the thermal energy to the fluid flowing from the inlet to the outlet. The electrical resistor is at least partly made in a substantially granular form and at least some granules of the electric resistor are made with a doped semiconductor and/or with a intermetallic compound.

摘要： A system includes a power supply for an electrochemical stack. The system may support operation in at least two modes: a first where power for the electrochemical stack originates from a renewable energy (e.g., an on-site) power source, and a second mode where power for the electrochemical stack is supplied at least in part from a power grid interconnection. A source power converter may adjust its operating voltage to select between prioritizing power from the on-site source and/or drawing power from the electrochemical stack at least in part from the power grid.

摘要： A control unit is configured to communicate with a terminal owned by a power company. When a hydrogen generation request is received from the terminal, the control unit determines whether hydrogen is to be generated based on a state of a hydrogen generation device, and transmits a determination result to the terminal. When a power sale request is received from the terminal, the control unit determines whether power is to be sold based on a state of the hydrogen generation device, and transmits a determination result to the terminal.
