Two paths to automation in hydrogen production
The automation of electrolyzers offers two approaches: centralized or decentralized architecture. Both pursue the goal of producing safe hydrogen in an efficient manner. The difference lies in the design and control of the system.
Centralized automation
Central automation is controlled via a central control cabinet. All sensors, actuators, and valves are connected via cable connections and are operated and controlled by a central controller. Overview and easy servicing – a space-saving solution where space is at a premium.
Decentralized automation
In a decentralized concept, intelligent automation components are located directly in the processes. The control of the system is thus distributed over several modules or units. These can be valve terminals or I/O modules in different systems, for example. This saves space in the control cabinet, reduces the amount of cabling required, and facilitates the modular expansion of your system.
Centralized, decentralized, or even both?
That depends entirely on the framework conditions. For a compact electrolyzer, a central solution is usually the best option. For larger systems with distributed modules, the decentralized variant is often the better choice. Of course, you can also combine both concepts. Why not benefit from the strengths of two architectures and implement your individual ideas?
Are decentralized systems too complex?
Many people think that decentralized automation is difficult to handle. However, modern systems can now be configured easily and intuitively. This makes commissioning easier and ensures that your system runs stably and without unnecessary interruptions.
