Comparison of systems
The choice between centralized and decentralized automation concepts for electrolyzers depends on various factors, for example:
- What are the requirements for the systems?
- What flexibility is required?
- How high must the reliability be?
- What is the maximum cost that may be incurred?
Depending on your requirements, both concepts offer advantages and disadvantages that you should weigh up carefully. For the best possible solution, the planning engineers should analyze the specific requirements of your system and consider the advantages and disadvantages of both concepts.
Concept 1: Centralized automation concepts for electrolyzers
Centralized automation concepts are based on a central control system controller or control unit. It is used to monitor and operate the entire system.
The main advantages are centralized data management and monitoring as well as the efficient use of resources. However, the susceptibility to failures is higher.
Concept 2: Decentralized automation concepts for electrolyzers
Decentralized automation concepts for electrolyzers distribute the control and monitoring to several decentralized units or modules.
Large systems, such as those found in the chemical or pharmaceutical industry, are usually controlled decentrally. For example, increased flexibility is important in the event of changes or extensions. The advantages of the decentralized automation concept clearly outweigh the disadvantages. At the same time, however, the integration of other systems is made more difficult.
