Hydrogen: the energy source of the future

Sustainable transformation of energy and industrial processes

Weidmüller offers customer-specific solutions for the digitalisation and monitoring of your hydrogen plant, from electrolysers to fuel cells and hydrogen refuelling stations. Rely on precise stack monitoring, safe automation and certified connectivity to make your processes more efficient and secure.

With our products and extensive experience, we actively support the process industry in developing and building sustainable solutions for hydrogen production. We place a special focus on modularisation to ensure a fast and successful ramp-up of the hydrogen industry.

Hydrogen systems: electrolysers and fuel cells

Electrolysers and fuel cells are the centrepiece of every hydrogen system. Electrolysis is the key process in hydrogen production, whereby various technologies have been developed to meet the different requirements of use and energy demand. From alkaline electrolysers to proton exchange membranes (PEM), anion exchange membranes (AEM) through to solid oxide electrolysis cells (SOEC), each type of electrolysis offers specific advantages.

At Weidmüller, we have extensive experience with all of these hydrogen technologies and offer customised solutions in electrical connectivity and automation to support efficient and reliable hydrogen production and use worldwide. Our stack monitoring solutions, cell voltage measurement boxes and connectivity for electrolysis stacks enable you to guarantee optimal performance of your systems. Our precise measurement and monitoring systems provide real-time data to monitor cell voltages and thus achieve maximum efficiency.

Overview of all solutions for electrolysers and fuel cells

An electrolysis system consists of several interconnected modules, including transformers, rectifiers, circulation pumps, heat exchangers, stack coolers, dryers and compressors. Each of these is essential for the smooth and efficient operation of the entire process. In addition to seamless integration, the system must be fully automated and fulfil strict safety certifications such as ATEX and SIL2/SIL3. With expertise in electrical connectivity, automation, hardware and software, Weidmüller offers comprehensive solutions for all these systems to ensure safe and efficient operation.

Hydrogen refuelling stations and hydrogen storage

Hydrogen storage and refuelling stations require seamless integration of various systems, from trailer changes and compression to cooling, fuel pumps and other components. All of these components must interact flawlessly to ensure efficient and safe operation. Weidmüller's modular approach enables customers to develop fully customised connectivity and automation systems. With our flexible and scalable solutions, every aspect of the storage and refuelling process can be optimised to ensure smooth operation and easy adaptation to future requirements.

Weidmüller offers high-performance automation and connectivity solutions for the operation of modern hydrogen refuelling stations. Our products are specially designed for the requirements of hydrogen infrastructure and offer the highest reliability even under extreme conditions.
