Do you already know which booths you want to visit at the hydrogen trade fair in Hamburg? Planning a trade fair visit can be tedious. That is why our editorial team has pre-sorted things for you and presents the trends and innovations here in the magazine in compact form, and in more detail in our newsletter. From the electrochemical core of the cell through the often underestimated periphery to tangible fields of practical application: with the H2international (H2int.) Travel Guide, you will more quickly find the innovations that are important to you.
Practical tip on booth numbers
The hydrogen section of the fair is located in halls B5, B6 and B7. The booth numbers given by the organizer start with the hall number without the “B.” So the “B” in 7B30 refers to aisle B in hall B7, and there you will find the German Hydrogen Association (Deutscher Wasserstoffverband) as well
as H2int.

Tanaka: catalysts, membranes and recycling processes
Tanaka Precious Metal Technologies is participating in the Hydrogen Technology World Expo in Hamburg for the first time. The focus of its trade fair presentation is on precious metal technologies for hydrogen production, gas purification and precious metal recycling. The precious metals platinum (Pt), palladium (Pd), iridium (Ir), rhodium (Rh) and ruthenium (Ru) are indispensable for many hydrogen technologies and a significant cost factor. Using them sparingly and recycling them is therefore essential.
Tanaka’s expertise covers electrode catalysts for fuel cells and electrolyzers, various catalysts beyond cell stacks (for example for steam reforming, for shift reactions, for exhaust gas treatment), hydrogen-permeable membranes and plated electrodes, as well as the recovery and processing of precious metals from hydrogen technologies.

Marquardt and Murrelektronik: decentralized automation meets stack monitoring
The automation specialist Murrelektronik and the Marquardt Group, which comes from the automotive sector, are placing their new cooperation at the center. They are showing a joint approach to the automation and monitoring of modular hydrogen systems. The focus is on combining measurement and safety technology near the stack with decentralized distribution of energy, signals and data.
Marquardt is contributing components from its hydrogen and energy management portfolio for this: Cell Voltage Monitoring continuously monitors cell voltages and can thus make anomalies in the stack visible at an early stage. It is complemented by the Cell Voltage Pick-Up for contacting bipolar plates, a high-voltage sensor for current and voltage measurement, and an H2 leakage sensor. The latter detects hydrogen concentrations from 0 to 4 percent by volume and is, according to the manufacturer, designed, among other things, for electrolysis plants.
Murrelektronik relies on the decentralized automation platform Vario-X. Control, sensor and actuator functions are integrated closer to the process, which is intended to reduce central control cabinet structures and wiring effort. For manufacturers of modular electrolyzers and for operators of growing plant fleets, this is relevant above all with regard to installation, scalability, commissioning and service.
The cooperation follows a co-creation approach: according to their own statements, both companies are working on interfaces, hardware and software integration, as well as on transferring experience from the automotive and industrial automation sectors to hydrogen applications. At the joint booth, it is intended to show how measurement data from the stack and the plant can be integrated into an end-to-end, scalable automation architecture.

Fraunhofer LBF (GreenMat4Hy): reality check for pipelines and plasma pyrolysis
The Fraunhofer Institute for Structural Durability and System Reliability LBF in Darmstadt, part of the Fraunhofer Performance Center for Hydrogen in Hesse (GreenMat4Hy), is devoting itself to the retrofitting of existing gas networks.
Thin internal coatings are intended to reduce direct contact between hydrogen and steel, thus preventing the feared hydrogen embrittlement. Fraunhofer LBF is developing methods to evaluate the adhesion, durability and service life of these coatings under realistic loads, and to make better investment decisions. A section of pipeline can also be seen at the trade fair.
The Fraunhofer Research Institution for Materials Recycling and Resource Strategies IWKS in Hanau is showing the model of a reactor for microwave-based plasma pyrolysis. The input materials can be, for example, plastic waste, oils or biogas. What is important is that hydrocarbons are present. With the help of the highly reactive microwave plasma, the substances are broken down without complex pretreatment. The result is hydrogen, synthesis gas and high-quality carbon. According to Fraunhofer, CO2 is not produced in the process itself.
