摘要： Systems and techniques for monitoring, assessing, and/or controlling hydrogen production are described. For instance, a system for monitoring, assessing, and/or controlling hydrogen production may include: a plurality of electrolyzers; and a controller configured to: obtain raw data indicative of respective operations of respective electrolyzers of the plurality of electrolyzers over a period of time; obtain command data indicative of one or more commands provided to the plurality of electrolyzers over the period of time; obtain event data indicative of one or more events related to the plurality electrolyzers that occurred during the period of time; generate state data based on the raw data, the command data, and the event data, the state data comprising a respective state of each electrolyzer of the plurality of electrolyzers for each of a number of discrete time periods of the period of time; and perform one or more operations responsive to the state data.

摘要： A modular system for hydrogen generation includes a plurality of cores electrically connected in series to a power supply, wherein each core includes an electrolyzer and a bypass circuit configured to electrically isolate the core from the power supply. The modular system also includes a hub including a water source and a controller, wherein the water source is in fluid communication with the electrolyzer of each of the plurality of cores, and the controller includes a switch activatable, in response to a triggering condition, to electrically isolate one or more of the plurality of cores from the power supply via a respective bypass circuit.

摘要： A method includes providing raw water into a first filter assembly to remove solids from the raw water to form a filtrate, providing the filtrate from the first filter assembly into a second filter assembly to electrochemically remove ionics from the filtrate to form purified water, and providing the purified water to an electrolyzer to generate hydrogen by electrolyzing the purified water.
