摘要： A system and method of power management for a power generation system is disclosed. A method of power management for a hydrogen generation system including one or more electrochemical stacks, the one or more electrochemical stacks receiving power from an electrical grid including at least one power source, includes: receiving a frequency or voltage reference value for the hydrogen generation system; continually monitoring a frequency or voltage of the electrical grid; and varying a load of the hydrogen generation system in response to the frequency or voltage of the electrical grid differing from the frequency or voltage reference value to restore the frequency or voltage of the electrical grid to the frequency or voltage reference value.

摘要： Systems and techniques are described herein for producing hydrogen. For instance, a method for producing hydrogen is provided. The method may include obtaining a current cost of power; obtaining historical power-cost data indicative of historical costs of power; determining a predicted cost of power based on the historical power-cost data; obtaining a request for hydrogen; determining a current value of hydrogen based on the request for hydrogen; obtaining historical hydrogen-value data indicative of historical values of hydrogen; determining a predicted value of hydrogen based on the historical hydrogen-value data; determining a rate for an electrolyzer to produce hydrogen based on the current cost of power, the predicted cost of power, the current value of hydrogen, and the predicted value of hydrogen; and controlling operations of the electrolyzer such that the electrolyzer produces hydrogen at substantially the determined rate

摘要： Systems and techniques are described herein for controlling hydrogen production. For instance, a method for controlling hydrogen production is provided. The method may include determining an amount of power for a hydrogen-production installation to consume based on one or both of an amount of power produced by a power producer or an amount of power consumed by a power consumer; and controlling hydrogen production at one or more electrolyzers of the hydrogen-production installation such that the one or more electrolyzers consume substantially the determined amount of power.

摘要： Provided herein are systems and methods for generating hydrogen and ammonia. The hydrogen is generated in an anion exchange membrane-based electrochemical stack. The hydrogen generated in the stack may be used to generate ammonia or may be used for other applications requiring hydrogen. The feedstock for the anion exchange membrane-based electrochemical stack may be saline water, such as seawater. A desalination module or a chlor-alkali stack may be used to treat the saline water prior to electrolysis in the anion exchange membrane-based electrochemical stack.

摘要： The systems and methods described herein provide for a mission critical control of a hydrogen generation system to ensure a downstream receiver receives a critical amount of hydrogen from the system and/or a hydrogen storage tank. In one implementation, a status of a hydrogen storage tank may be compared to a mission critical threshold value and hydrogen may be supplied to the tank to ensure the hydrogen does not fall below the threshold value. Further, the hydrogen generator may utilize reliable sources of energy, such as grid power, to refill a storage tank in response to the tank being below a threshold value. At other times, however, the hydrogen generator may utilize renewable sources of energy to provide a more eco-friendly hydrogen producing system.

摘要： The present disclosure relates to circuits for connecting components of a hydrogen plant to a power grid to power the components in an efficient manner. In one implementation, power-side alternate current (AC) to direct current (DC) converters may be connected to a source power grid without the need for an isolation transformer by providing separate buses between the power-side AC-DC converters and load-side DC-DC converters instead of a shared DC bus between the converters. Other implementations for connecting components of a hydrogen plant to a power grid may include an adjustable transformer, such as a tappable transformer or an autotransformer, to connect any number of auxiliary loads of the plant to the power grid. The adjustable transformer may provide for various types of auxiliary load devices to connect to the power provided by the transformer at the same time, including both three-phase devices and one-phase devices.

摘要： The systems and methods described herein provide for control of hydrogen generation based on one or more characteristics of an input power signals, including a voltage of the input power signal and/or a frequency of the input power signal. The hydrogen generation system may be controlled in response to a reactive power consumption of the hydrogen generation system and/or a reactive power component of a power grid providing energy to the hydrogen generation system. In one embodiment, the hydrogen generation system may be controlled to generate reactive power in circumstances in which a voltage an input power signal is less than or more than a voltage range. In another embodiment, the hydrogen generation system may control hydrogen production based on a frequency of the input power signal.

摘要： Systems and techniques are described herein. For instance, a method for producing hydrogen is described. The method includes determining an amount of reactive power for an electrolyzer of a hydrogen-production installation connected to a power grid to generate, or to consume; and controlling operations of the electrolyzer such that electrolyzer generates, or consumes, substantially the determined amount of reactive power. Additionally, a system for producing hydrogen is described. The system includes a connection to a power grid configured to receive electrical power from the power grid; one or more electrolyzers configured to receive the electrical power and to produce hydrogen; and a controller configured to: determine an amount of reactive power for the one or more electrolyzers to generate, or to consume; and control respective operations of the one or more electrolyzers such that the one or more electrolyzers collectively generate, or consume, substantially the determined amount of reactive power.
