Dear users, due to planned maintenance work you might not be able to see product search results, beginning from today (24/09/2024) 10:00 PM CET. We aim to have the full functionality restored by 2:00 AM CET.
Control and monitoring of electrolyzers
Increase the efficiency and cost-effectiveness of your electrolysis plants with our scalable, safe, and open control and monitoring solutions.
In order to noticeably reduce process costs, more than ever before, solutions are in demand that make the operation of electrolysis plants efficient and cost-effective. Acquiring and transmitting the field data required for digitalization is, however, a complex task and must not negatively impact operational safety. For instance, the power supply must be guaranteed during both operation and system downtime. Furthermore, it is important to control the electrolysis process, including the startup and shutting down of the entire system, to overcome fluctuations in the renewable energy generated by wind and solar power. In addition to this, the heat generated by the process and the circulating pumps needs to be dissipated, and the temperature of the water and electrolyte regulated. And finally, numerous process parameters – and in particular the purity of the hydrogen generated – have to be monitored via sensors.
Solution
Consistent digitalization of systems and processes
With our open PLCnext Technology ecosystem, you can control and monitor the entire electrolysis with the corresponding processes and systems. The solution also supports maintenance concepts based on diagnostic signals. PLCnext Technology acquires the sensor data synchronously and evaluates it in the appropriate format, allowing electrolyzers to be controlled with a complete set of current data. Planning and decision-making processes are shortened, thereby increasing the efficiency of the electrolyzers through intelligent data use. AI-supported evaluations can detect deviations from the system’s standard behavior. It is possible to link to external databases as well as model and scenario calculations via Matlab Simulink or PLCnext Technology.
Access to decentral electrolysis plants
We offer various options for secure remote access to your electrolysis plants. This means that you can perform maintenance and service jobs quickly and efficiently and significantly reduce costly and time-consuming on-site service calls. For data transmission, we offer our mGuard Secure Cloud solution. This turnkey remote maintenance solution connects service personnel and systems over the Internet securely and reliably. The mGuard Secure Cloud uses highly secure VPN tunnels and ensures the confidentiality, authenticity, and integrity of data transmitted between the devices.
Structure of an example control and monitoring solution
Our products and solutions enable hydrogen production to be controlled in the control center of the electrolyzer. In addition, they monitor tank levels, control the feed-in of the electrolytes, and control the fans, ventilation, and water pretreatment. Furthermore, we ensure electrical load management and safety-related applications, including emergency shutdown.
Security routers
With comprehensive security functions, the mGuard security routers protect your industrial network against unauthorized access by people or malware.
COMPLETE line – industry-specific solutions for the control cabinet
Set up control cabinets quickly and easily with the comprehensive and coordinated COMPLETE line product portfolio. The COMPLETE line products have a uniform design and uniform haptics, which makes them very easy to install.
I would be happy to advise you on the way to a carbon-neutral future with green hydrogen.
We have the right answers to all electrical engineering questions regarding the design and operation of electrolyzers. This applies to control and monitoring as well as to security issues, whether they affect cybersecurity or explosion protection.
Guaranteed safety
Electrolysis plants are covered by the KRITIS regulation for critical infrastructure. In addition, the increasing networking requires security, safety, and explosion protection to be examined side by side. We offer certified products and solutions as well as supporting services in order to minimize your safety and liability risks and to protect your system productivity.
Functional safety mechanisms must be regulated in such a way that failures or potential hazardous situations can be managed. This is best achieved by means of a tailored safety concept.
We provide services to cover the entire safety lifecycle. In addition, our wide range of safety applications is certified in accordance with IEC 61508 and IEC 61511. To keep up to date with the latest knowledge, we will be happy to support you with training courses for employees.
Due to the occurrence of flammable gases, the topic of explosion protection is crucially important in the hydrogen industry. We offer a comprehensive selection of products and solutions for implementing the requirements in potentially explosive areas with various zones. If necessary, we will also train your employees. Furthermore, we support you with the validation and documentation of intrinsic safety.
Digital transformation and the increasing complexity of cyberattacks require a holistic security strategy. In addition, the implementation of cybersecurity measures is a legal requirement. Good protection against cyberattacks can only be achieved if coordinated technical and organizational measures are intermeshed.
This is why we offer a comprehensive 360° security concept that includes secure services, solutions, and products. This simplifies the protection of your systems and offers all-round protection for your plant.
Feel free to contact us. Together, we will find an optimum solution for equipping your control cabinets with our more than 100,000 products from connection, communication, and automation technology.
