Description

Electrolytic module cluster Background Recently, the number and scale of water electrolysis projects for the production of "green" hydrogen gas have been declared to increase dramatically. The current solutions for electrolysers focus on two solutions, one being a container-type solution in which the entire electrolyser is in one or a few containers. Another solution is to have medium and large electrolytic devices with power consumption from 1MW to several GW, planned from a single component, or built from prefabricated modules. Disclosure of Invention The requirements for medium and large electrolysis plants, in addition to high overall efficiency and high safety of the plant, as well as robust and long-term operation and low maintenance times, include dynamic operation modes, simple replacement of faulty components and simple integration of new components for expanding the plant capacity. In this case, costly components, such as electrolytic reactors, should be protected during operation. These requirements are more difficult to meet with current control schemes for large devices. For example, if all of the equipment components of the system are centrally controlled, a fault in one portion of the system may also cause downtime for other portions of the system that were otherwise operational. Furthermore, such central control requires a complex software architecture. According to an aspect of the invention, an electrolysis module cluster and a multi-electrolysis module cluster according to the features of the independent claims are presented. Advantageous configurations are the subject matter of the dependent claims and the following description. According to one aspect of the invention, an electrolysis module cluster having a first electrolysis module and a second electrolysis module is presented. Here, each electrolysis module has an electrolysis reactor system with a plurality of actuators and a plurality of sensors. Additionally, each electrolysis module has an output connection configured to provide the generated electrolysis gas, a water supply connection, and power electronics coupled to the electrolysis reactor system for providing electrical energy. Each electrolysis module also has control and regulation electronics that are signal-coupled to the plurality of actuators and sensors, respectively, and the power electronics. The control and regulation electronics are configured to operate the respective electrolytic reactor system in an autonomously regulated manner by means of the actuators and the power electronics, based on signals from a corresponding plurality of sensors of the electrolytic reactor system and on the electrolysis product quantity demand provided to the respective electrolytic module and on one of a plurality of operating modes provided to the respective electrolytic module. The control and regulation electronics of the first and second electrolysis modules, respectively, are configured and arranged to be signal-coupled to the control interface for providing the autonomous regulated operation of the respective electrolysis module with a corresponding operating mode and/or a corresponding electrolysis product quantity requirement, respectively. The electrolytic reactor system may have an electrolytic reactor, a plurality of actuators, and a plurality of sensors. The power electronics may be provided for coupling with a power supply network, in particular via a transformer. The individual electrolysis modules can be provided for operation in a plurality of particularly selectable operating modes. With the aid of the electrolysis module clusters, it is possible, for example, to construct medium-or large-sized electrolysis units in such a way that a plurality of electrolysis modules can be connected to form a cluster of individually autonomously regulated electrolysis modules, which each have hardware-and software-compatible and/or structurally identical interfaces and/or signal interfaces. The clusters can be based on compatible interfaces and/or signal interfaces as units that are regulated by means of control interfaces for being able to generate the provided electrolysis product quantity demand. The control interface can provide the electrolytic modules with different operating modes for operating the respective electrolytic modules, so that the operation of the clusters can be optimized in terms of operating parameters, such as service life and/or product quantity, and on the basis of the specifications of the individual electrolytic modules and/or the operating history of the individual electrolytic modules. The individual electrolysis modules may have a uniform production capacity, for example an electrical power consumption of 2.5MW, alternatively or additionally electrolysis modules of different production capacities may also be combined into the cluster by means of compatible and/or structurally identical interfaces. The production capacity of the individual electrolysis m
